Departments 1 Dean’s Message Denise Applewhite John Jameson ’04 Frank Wojciechowski 32 www.princeton.edu/ Engineering/eqnews DEAN’S MESSAGE Leveraging the strengths of many to solve global societal problems My association with Princeton Engineering extends more than three decades, yet I am still impressed with what I have learned about this school and the overall University in the last six months. The end of November marked my first half year as dean, and I am both happy and humbled to report what I have found, including the depth and extent of the support that the engineering school enjoys from the Princeton administration, our colleagues across the campus and our incredible group of alumni. The picture that has emerged is one of an exceptionally vital institution with a distinguished tradition of excellence in research and teaching. Moving forward, the most important questions for the engineering school are: How can we best organize our teaching and research to address the major challenges facing society? How can we improve human health around the world? How can we clean up the environment? What are the most promising sustainable sources of energy? How do we detect and prevent threats to our security? These very complex questions require technological solutions, but not just technological solutions. The best answers will involve a synthesis of fundamental science, creative engineering and expertise from other fields including economics, public policy and the humanities. Longterm solutions also require that we prepare our students to be leaders who integrate a foundation in technical domains with a broad understanding of society and history. In many ways, the engineering school at Princeton is built around such connections. In this magazine, you will read about work by engineers who, in close collaboration with colleagues across the University and around the world, are developing sustainable energy sources. Robert Socolow, for example, is a professor of mechanical and aerospace engineering who has become a leading voice on how to reduce greenhouse gas emissions over the next 50 years. Rob is a member of the Princeton Environmental Institute, which connects scientists, engineers and policy experts. Engineers also work closely with the Woodrow Wilson School of Public and International Affairs, which includes world renowned climate expert Michael Oppenheimer; with the Princeton Plasma Physics Lab, the nation’s first lab for developing nuclear fusion energy; and with the U.S. Geophysical Fluid Dynamics Lab, one of the world’s leading sources of climate models. Another major new cross-disciplinary effort is the Mid-Infrared Technologies for Health and the Environment (MIRTHE) center, which was awarded initial funding of $15 million from the National Science Foundation. Led by electrical engineer Claire Gmachl, this project brings together six universities and a growing list of corporate partners to take new sensor technology from the lab to the marketplace. We expect the results to bring major improvements to medical diagnostics, environmental monitoring and homeland security. These resources give us the opportunity and responsibility to pursue big problems while creating a rich educational environment. Our Center for Innovation in Engineering Education, now under the leadership of outstanding teacher and researcher Sharad Malik, is ensuring that we educate students—engineers and non-engineers—to be leaders who carry forward the spirit of inquiry, innovation and service that is so abundant at Princeton. As I look forward to the rest of my first year as dean and many years ahead, I am excited by the opportunities before us. I encourage readers of this magazine—our colleagues in academia, industry and government, prospective students and Princeton alumni—to learn more about us and to help us in this enterprise of leveraging Princeton’s strengths to solve problems and create opportunities around the world.

Photo by Shin Jae Won of the Daily Princetonian eqn Winter 2006–07 It is difficult to name a major media outlet that did not feature, in the frenzied run-up to the November elections, Princeton computer scientist Edward Felten’s now-famous electronic voting machine hack. Among those that did: Time, the NewsHour with Jim Lehrer, the Los Angeles Times, the Philadelphia Inquirer, the Wall Street Journal, Technology Review, ABC’s World News Tonight, Agence France-Presse, Fuji-TV and NPR’s Weekend Edition Saturday with Scott Simon, Science Friday, and the Diane Rehm Show (twice). The media juggernaut launched almost immediately after Felten and colleagues published a paper and video, describing the hack, on the website of Princeton’s new Center for Information Technology Policy, which addresses crucial issues at the intersection of society and computer technology. Felten and graduate students Ariel Feldman and Alex Halderman ’03 spent their summer analyzing a Diebold AccuVote-TS electronic voting machine that they obtained through a private party and then creating demonstration vote-stealing software to infect it. “We found that the machine is vulnerable to a number of extremely serious attacks that undermine the accuracy and credibility of the vote counts it produces,” wrote Felten and his co-authors in their paper. The software, which can be installed within a minute, can fraudulently change vote counts without being detected and then act as a virus, spreading silently from machine to machine during the normal process of preparing machines and aggregating vote totals. The researchers also showed that the lock protecting the machine could be easily picked or, alternatively, opened with a mass-produced key commonly used on jukeboxes, filing cabinets and hotel minibars. They demonstrated various hacking scenarios in a 10-minute video. The week after their postings, Felten, Feldman and Halderman appeared nationally on Fox News and CNN and gave live demonstrations showing how the software could sabotage a mock presidential election between George Washington and Benedict Arnold (though Washington received more votes, Arnold won both times). When several people uploaded the researchers’ video to YouTube, the popular video-posting website, the Diebold hack was soon rated one of the site’s most popular videos. Although the CNN and Fox News live demonstrations went flawlessly, the researchers were besieged by some last-minute glitches. Felten and Feldman were up until 2 a.m. the night before, squashing a last minute bug in their vote stealing software. Before going to bed they handed it off to Halderman who ran the program repeatedly for hours to make sure there would be no problems with the on-air demonstrations. Felten said the team created the software, which they keep carefully guarded lest it fall into malevolent hands, in the spirit of helping to guide public officials in better securing elections. Diebold responded that Felten and his students had an old version of the voting machine software and thus their findings were irrelevant. Felten countered that the software he studied was used in actual elections and that Diebold claimed at the time it was secure. His group has offered to test a current version to see whether the problems have been fixed. When Randall Stross—a writer for The New York Times who described the trio’s work as a “devastating critique”—contacted Diebold and asked if the company would supply Felten with a current version of the machine to test, it declined to do so. Felten said his offer remains open to Diebold or any other manufacturer of electronic voting machines. “We would be happy to study any of these paperless systems,” he said. Felten, Feldman and Halderman have been examining the tightly contested race in Florida for the House seat being vacated by legislator Katherine Harris. In that race, 13 percent of electronic ballots did not register a vote for the House race even though they included votes for candidates in lesser races, such as that for the local hospital board delegate (normally the discrepancy is about 1 percent). At press time, few election fraud allegations had surfaced. But that was not particularly reassuring for Felten. “Even if we don’t see any glitches, that doesn’t mean there aren’t any problems,” said Felten. “Many problems would be invisible and impossible to detect.” He noted, for example, that a recount in the close Virginia Senate race would not really have made a difference because Virginia requires no paper record to accompany electronic voting. “You can’t really do a recount if you don’t have a paper record.” Felten said he hoped lessons from this election would increase Congressional support for closer scrutiny of electronic voting. In the last session, Rep. Rush Holt, D-N.J., authored a bill that would mandate a verified paper trail, random post-election audits and more openness from voting machine vendors. In September, Felten testified before the House Administration committee on the need for such reforms. More than half the House mem- bers cosponsored the bill, but it languished in committee. “The elections are over,” said Halderman, “But democracy continues. There is time to do a lot of good for the 2008 election.” Now that the media siege has abated, Felten will be establishing the coming agenda for his new center, which is a joint initiative of the engineering school and Princeton’s Woodrow Wilson School of Public and International Affairs. It is funded in part by a grant from Microsoft. “This is just one example of the kind of work the center will do,” said Felten. ­—Teresa Riodan MIRTHE center draws ‘roadmap’ for future of mid-infrared technologies Noninvasive medical devices that detect disease by analyzing a single human breath are likely to be the blockbuster applications that launch mid-infrared laser technology, according to participants in a recent “roadmapping” exercise at Princeton. More than 60 representatives from 35 companies, government laboratories and nonprofit corporations participated in an all-day workshop July 11 to share their visions for Mid-Infrared Technologies for Health and the Environment (MIRTHE), an engineering research center based at Princeton and funded through a major grant from the National Science Foundation. The day was designed to provide an opportunity for industry professionals to identify goals for MIRTHE’s direction, said Claire Gmachl, the center’s director and an associate professor of electrical engineering. “The process encapsulated the center’s commitment to engage industry,” said Joseph Michels, MIRTHE managing director and director for research initiatives at the Princeton Institute for the Science and Technology of Materials. “It’s very different from your standard collaborative research project. Instead of making a discovery and looking for companies to develop it, we are asking companies what technologies they need or would potentially be interested in before our research even starts.” The focus of the MIRTHE center is the development of sensors that rely on a new type of laser to detect minute amounts of chemicals found in air, the environment and human breath. In 2005, Gmachl was awarded a MacArthur “genius grant” for her work on these devices, called quantum cascade lasers, which are the first compact, easy-to-use source of light in the mid-infrared portion of the spectrum. Mid-infrared light reveals many chemicals, including ammonia and carbon dioxide, that are invisible to other wavelengths. The roadmapping exercise was but one part of an ongoing conversation, Gmachl said, as today’s sensors and their applications are constantly evolving. Industry participation with the center already has yielded “surprising” insights, she said, including an unexpected level of interest in sensors designed for liquid environments. These devices could detect pollutants in streams and rivers or examine gases in the blood. Participants also said that a prime area for exploration would be sensors that monitor combustion and other industrial scale processes. Corporate partners said it is essential to increase the number of reliable laser sources and stressed the desirability of sensors that can function in varied conditions. This would permit the use of the devices in real-world environments, such as power plant smokestacks where sensors could analyze emissions and air quality. Since it started in May, the MIRTHE center has attracted more than ten industry and non-profit members, including multinational electronics giant Siemens and California-based molecular detection and imaging firm Daylight Solutions. The investment firms Consensus Business Group and GHO Ventures also signed on, as did the Pacific Northwest National Laboratory, the leading federal lab for environmental monitoring and counter-terrorism research. “As a MIRTHE member, Siemens sees an excellent opportunity to collaborate with university faculty and students to produce breakthrough innovations,” said Paul Camuti, president and chief executive of Siemens Corporate Research. “We see applications for MIRTHE technologies in the healthcare, security and environmental markets, both here in the U.S. and around the world. In addition, MIRTHE makes it easy to partner with different institutions and companies to (From left) MIRTHE deputy directors Anthony Johnson of University of MarylandBaltimore County and Matthew Fraser of Rice University stand in the lab of center director Claire Gmachl with managing director Joe Michels, both of Princeton.

Photo courtesy of James Smith educate future researchers about our needs. The roadmapping exercise provided the right forum to learn about MIRTHE and for Siemens Corporate Research to provide input to the future direction of the center’s initiatives.” Because MIRTHE researchers are at the forefront of the field, they are able to educate their corporate colleagues about sensor technologies as they emerge, said Joseph Montemarano, the director for industrial liaison in the Princeton Institute for the Science and Technology of Materials. An ongoing dialogue will enable industry professionals to make well-informed decisions when faced with investment opportunities, he said. In addition to the initial work with corporate partners, collaborative research has begun among scientists and engineers from MIRTHE’s six partner universities—Princeton, Texas A&M University, Rice University, Johns Hopkins University, the City College of New York and the University of Maryland-Baltimore County. James Smith, Princeton professor of civil and environmental engineering, is currently working with two measurement platforms housed at Princeton that rely on MIRTHE technologies. The first, a Laser Imaging Detection and Ranging system that measures atmospheric aerosols, is a partnership with scientists and engineers at City College. The second, called an eddy covariance station, will measure the turbulent fluxes of carbon dioxide, water vapor and nitrogen compounds between the land surface and atmosphere. Smith, who is collaborating with scientists and engineers at Rice, UMBC and Princeton, has installed the 20-foot-tall station near the Broadmead detention pond in Princeton. Smith and his collaborators believe the instruments they develop will provide previously unattainable information about the carbon, nitrogen and water exchange between the land surface and the atmosphere. These key data could advance the quest to understand and mitigate global environmental change, he said. (See story, page 15.) “It opens up all kinds of doors for research,” he said. MIRTHE also has begun a number of educational activities, including the creation of the “MIRTHE Academy,” a core group of graduate and undergraduate students involved in research projects and exchange programs between the member universities. Future MIRTHE educational outreach initiatives will target students in kindergarten through twelfth grade, teachers and members of the general public. A major goal of these efforts, Gmachl said, will be to provide people with a “bigger vision” of mid-infrared technology and its inherent possibilities. —Hilary Parker Princeton’s patent value ranked third among universities IEEE Spectrum ranked Princeton third among universities in its assessment of “the world’s most valuable patent portfolios.” The ranking was published in the magazine’s November issue. “This reflects the strength of patents in the engineering school and the greater University,” said John Ritter, director of the Office of Technology Licensing and Intellectual Property at Princeton. According to Ritter, nearly three-quarters of patents granted to Princeton are for research in the engineering school. The Massachusetts Institute of Technology ranked first and the University of California system ranked second. Stanford University, the University of Michigan and the California Institute of Technology rounded out the top six slots. The ranking took into account four indicators: eqn Winter 2006–07 •Pipeline growth: the university’s trend in patenting, measured by dividing the number of patents obtained in 2005 by the annual average for the years 2000 through 2004. •Pipeline impact: how frequently the university’s patents are cited in other patents. • Pipeline generality: the variety of technologies that might spring from a patent. • Pipeline originality: the number of original inventions compared to the number of inventions that were incremental improvements on existing technology. The article also ranked companies in terms of patent power. The full article can be found online at www.spectrum.ieee.org/nov06/4699. In the spring, Princeton’s Center for Innovation in Engineering Education will sponsor its second Innovation Forum, which will feature cutting edge research across Princeton with robust potential commercial applications. See www.princeton.edu/engineering/ciee for updates about the engineering forum. —TR eQ N E W S Beyond encryption, new stealth technique hides messages Princeton engineers have invented a method of stealth communication that disguises not only the information contained in a message, but the existence of the message itself. Today’s encryption technologies rely on computer programs to scramble information, but the fact that a message is being sent is still detectable to outside parties. Evgenii Narimanov, assistant professor of electrical engineering, and graduate student Bernard Wu have taken security to a new level, hiding the transmission in the “static”—or minute random light pulses—found along the fiber-optic cables in all public networks. “One would use this stealth not instead of, but in addition to encryption,” Narimanov said, thereby providing the greatest security possible. Narimanov and Wu presented their proposed method at the annual meeting of the Optical Society of America on Oct. 9. The most exciting thing about this form of stealth, Narimanov said, is that it would use existing technology and networks. His system relies on a technique called CDMA (code-division multiple access), which spreads radio transmissions across the spectrum and is widely used in increasing the capacity of cell phone networks. Narimanov, whose research arises from his background in theoretical physics, is working with electrical engineering professor Paul Prucnal to test the concept experimentally. The CDMA encoder would be used to transform the message into a lengthy series of small signals that are imperceptible against the ever-present background noise in public information networks. Upon receipt of the transmission, the appropriate party could use a similar method to recondense the message, provided the recipient was aware of how it had originally been manipulated. Though the method is not yet in use, this “cheap and fast” technique could lessen the need for organizations to build and maintain more secure and more expensive networks, he said. “This can be done at many levels—from long-haul all-optical networks to the really small ones, such as a fiber network on a ship or on an airplane,” Narimanov said.—HP Electrical engineering faculty members Evgenii Narimanov (left) and Paul Prucnal are collaborating to conduct practical tests of a stealth communication technique developed by Narimanov and graduate student Bernard Wu. Photo by Steven Schultz ‘Gigascale’ project pushes Moore’s Law to its limits and beyond Four Princeton researchers are working on a major project to ensure that computing capability continues to increase long after individual transistors reach their physical limits. As transistors approach the nanometer scale, many challenges must be met to match the rate of advancement described by Moore’s Law, said Sharad Malik, the associate director of the Gigascale Systems Research Center, a project involving 41 researchers at 17 institutions. Based on an observation by Intel founder Gordon Moore, the law describes the increase in computing capacity made possible by decreasing the size and thus roughly doubling the number of transistors on computer chips every two years, an escalation that’s gone unabated for 40 years. Malik and his Princeton colleagues, computer scientist David August and electrical engineers Margaret Martonosi and Li-Shiuan Peh, are contributing to the center’s efforts to design new ways to meet the growth described by Moore’s Law even after transistors can no longer be made smaller or faster. The center recently received renewed funding from the Microelectronics Advanced Research Corporation, an industrial consortium, and the Defense Advanced Research Projects Agency. One of the challenges is to use hundreds, or even thousands, of processors effectively on a single chip, Malik said. This division of labor among separate processors allows greater computing power without resorting to the conventional method of increasing the speed of individual processors, which consumes exorbitant amounts of power. Although preliminary applications of this technique are commercially available in chips with two to four processors, Malik said it remains difficult to divide computer problems among many parallel processors. August, Martonosi and Peh are working to solve the challenges presented by these devices while also tapping their potential. “Having billions of transistors at the nanometer scale also poses a significant reliability challenge,” Malik said. His research involves mitigating these problems through the design of systems that work even if all of their components do not. As physical limits are approached, it is possible that new devices may replace traditional transistors, Malik said. A key part of the center’s research aims to ensure that computing capabilities continue to grow even as a migration to these devices takes place. eqn Winter 2006–07 eQ N E W S A Princeton faculty member since 1991 and the director of Princeton’s Center for Innovation in Engineering Education, Malik lauded the Gigascale Systems Research Center as “a tremendous resource” for Princeton students. They participate in collaborative projects with leading academics and researchers from industry leaders, including IBM and Intel. “The students are part of this cutting-edge dialogue on the changing face of the entire industry over the next 10 to 15 years,” he said. —HP Malik becomes director of Center for Innovation in Engineering Education Above: Sharad Malik. Left: Bob Monsour. Photos by Denise Applewhite. Sharad Malik, George Van Ness Lothrop Professor in Engineering, has been named director of Princeton’s Center for Innovation in Engineering Education. The freshly minted center begins its second academic year with an ambitious agenda that includes two lecture series, an internship initiative and innovative curriculum offerings for undergraduates and graduate students. H. Vincent Poor, dean of engineering and founding director of the center, said he has high expectations for the center under Malik’s stewardship. “Sharad is a stellar talent in his field of research, in the classroom, and as a leader,” said Poor. “He embodies the very qualities that CIEE aspires to nurture in students.” Malik said that CIEE’s primary role is to serve as an incubator for new ideas in engineering education. The center is pioneering new interdisciplinary approaches to teaching engineering as well as new approaches to the teaching of core technological concepts to non-technical majors. “One of our goals is to help equip students—whether they are engineers or nonengineers—with the skills they will need to be technologically astute leaders of the future,” said Malik. “We need to cultivate and grow the pathways between the engineering school and the greater University. All students on campus should have access to the rich opportunities that the engineering school offers and engineering students should be working shoulder-to-shoulder with their colleagues elsewhere on campus as they tackle real-world problems.” Malik’s research expertise is the computeraided design of electronic systems. (See ‘Gigascale’ story, page 5.) Malik has been honored three times with the Undergraduate Engineering Council’s Excellence in Teaching Award. Among CIEE’s curriculum initiatives are: •A course in community-focused design taught by Edward Coyle *82, Kenan Visiting Professor for Distinguished Teaching and eqn Winter 2006–07 co-founder (with Princeton alumna Leah Jamieson *77, dean of engineering at Purdue University) of Engineering Projects in Community Service. (See story, page 7.) •A course titled “Faster and Higher: Hypersonics and Space Exploration,” taught by Roger Burk, a visiting professor from United States Military Academy. •A course in patent law for engineers, taught by Margaret Radin, a visiting professor from Stanford Law School who this year is a fellow with the Woodrow Wilson School’s Program in Law and Public Affairs. • A course in innovation process management taught by Karl Zaininger *64, chairman and CEO of Global Technology Management Partnerships and visiting professor of mechanical and aerospace engineering. • An interdisciplinary course called EMP (Engineering, Math, Physics), led by Class of 1950 Professor of Chemical Engineering Pablo Debenedetti, designed both to give freshmen early exposure to engineering and integrate the teaching of math and physics in an engineering context. • Writing seminars for engineering graduate students, taught by Judith Swan, the Princeton Writing Program’s assistant director for scientific and technical writing. The center also seeks to highlight popular existing courses, such as the “High-Tech Entrepreneurship” class taught by Ed Zschau ’61, visiting lecturer with the rank of professor, and “Entrepreneurial Engineering,” taught by Dan Nosenchuck, associate professor of mechanical and aerospace engineering. Another major initiative of the center is to increase the opportunities for students to engage in internships and gain hands-on experience. Longtime entrepreneur Bob Monsour has been appointed as the center’s associate director and is leading the internship effort. (For details about Monsour, his new work at Princeton Engineering and his experience as a founder of an early computer industry phenomenon, see an online article at engineering. princeton.edu/news/monsour.) eQ The center is sponsoring two lecture series this academic year. On Oct. 19, Norman Augustine, former chairman and chief executive officer of Lockheed Martin Corp., delivered the inaugural talk in a new lecture series titled “Leadership in a Technological World.” And in partnership with the Jumpstart New Jersey Angel Network, the center hosts a lecture series on technology entrepreneurship. The first event in that series this year was an Oct. 25 N E W S panel discussion of entrepreneurial experiences and opportunities created by the emergence of India as a technology power. (See stories, page 8-9.) Malik emphasizes that the center’s mandate is to be experimental. “Some initiatives will succeed and some will fail but we will always be trying new things,” he said.—TR New course combines engineering and community service An innovative teacher and researcher, Edward Coyle *82 connected the dots when he saw engineering students in need of real-world design experience and local non-profit organizations struggling to use technology to better serve the community. The result of Coyle’s insight is Engineering Projects in Community Service (EPICS), a program he and Leah Jamieson *77 cofounded at Purdue University in 1995 to pair teams of students with local educational and service organizations. Now a Kenan Trust Visiting Professor for Distinguished Teaching, Coyle brings the program to Princeton this year, making the University one of nearly 20 throughout the world to offer the educational experience. “The goal is to have every student doing something that’s relevant to their discipline,” Coyle said, including engineers and non-engineers. EPICS is sponsored jointly by Princeton’s Center for Innovation in Engineering Education and the Community Based Learning Initiative and has so far attracted early applications from students in many departments, from engineering to the Woodrow Wilson School of Public and International Affairs. Though they register for the course in the spring, Princeton students in EPICS already have begun working with their partner organizations and will continue to do so throughout the academic year. An option exists to enroll in the course for two additional years, thereby satisfying three course requirements. Two projects, each with eight team members and a faculty advisor, are now in the planning stages at Princeton. The first will partner students with the Stony Brook-Millstone Watershed Association to transform the organization’s 30-year-old Buttinger Nature Center into a model “green” building. “The project is about environmental sustainability and energy,” said the team’s faculty adviser Catherine Peters, an associate dean of academic affairs in the School of Engineering and Applied Science and a professor of civil and environmental engineering. “This is one of the most important technological problems facing future generations of engineers.” The second project pairs a team jointly with Isles, a Trenton-based community organization, and Princeton Young Achievers, an after-school program for Princeton elementary students from low-income families. Under the guidance of mechanical and aerospace engineering professor Michael Littman, the team will renovate an eighteenth-century clock in a factory building owned by Isles while creating a hands-on engineering experience for the Princeton Young Achievers. “I think it’s a wonderful program,” said Bob Ellis ’79, a mechanical engineer at the Princeton Plasma Physics Laboratory and a Princeton Young Achievers board member. “It’s the sort of thing you’re not really accustomed to seeing out of engineering schools.” Catherine Peters, professor of civil and environmental engineering, introduces students to a “green building” project at the New Jersey Stony Brook-Millstone Watershed Association. The student team will pursue the project this spring as part of a new course. Photo by Frank Wojciechowski eqn Winter 2006–07 eQ N E W S In addition to the benefits for the Princeton Young Achievers, many of whom have never before had tangible experience with mechanical objects and processes, Ellis said the experience will help Princeton students when they enter “the real world” after graduation. This has been verified for Coyle many times in the past decade. A Motorola recruiter once told him that EPICS participants have a three- to four-year advantage over other recent college graduates, and Coyle has found that increasing numbers of companies actively seek students with EPICS experience. The seeds of EPICS were sown when Coyle was an undergraduate at the University of Delaware. Three years of experience on an electronic printing project with electrical engineering professor Peter Warter ’54 *62, a former vice-president of the Xerox Corporation, taught him the power of hands-on projects. At Purdue, Coyle teamed up with colleagues Jamieson, the current dean of Purdue Engineering, and Hank Dietz, now a professor at the University of Kentucky, to create EPICS. Here at Princeton, alumni connections have been instrumental in getting the program off the ground. In addition to Ellis, many of the key players in the new partnerships are University graduates, including Isles’ founder, president and chief executive officer Martin Johnson ’81, Isles’ research associate Joseph Robinson II ’05 and Jim Waltman ’86, the Watershed’s executive director. Now that EPICS has arrived at Princeton, Coyle said his goal is to ensure the program continues to grow long after he returns to Purdue in the fall. With plans to expand the current projects already in the works, perhaps with the addition of a new wing to the nature center, and a long list of potential partner organizations, he is confident of EPICS’ future success at the University. The potential also exists for the commercialization of technologies developed through EPICS partnerships, he said. In March, Princeton will host the 2007 National Idea to Product Competition for socially-focused entrepreneurship projects. Princeton’s EPICS teams will have a chance to gain feedback and guidance from industry professionals at the event as they compete against other entrants for cash prizes.—HP Leadership in action: Augustine shares insights from pioneering career Photo courtesy of Lockheed Martin eqn Winter 2006–07 Great leaders help create other great leaders, Norman Augustine ’57 *59 told a Princeton audience Oct. 19 as he did just that, sharing his insights on leadership to inaugurate the engineering school’s “Leadership in a Technological World” lecture series. Augustine, the former chairman and chief executive officer of Lockheed Martin Corp. with leadership experience in industry, academia, government and the non-profit world, earned his bachelor’s and master’s degrees in aeronautical engineering from Princeton. Calling him a leader who embodies Princeton’s informal motto, “in the nation’s service and the service of all nations,” Dean of Engineering H. Vincent Poor *77 said Augustine was the perfect choice to kick off the new series, which is sponsored by the Center for Innovation in Engineering Education. “The main goal of the center is to educate leaders, both engineers and non-engineers, who can lead what is becoming increasingly a technological world,” Poor said. Using positive and negative examples to illustrate 12 necessary “ingredients” for true leadership, Augustine touched on everything from the Boston Celtics basketball team to a fateful decision that led to the 1986 Challenger space shuttle disaster. Attributes including integrity, vision, courage and selflessness come together in diverse combinations in leaders who have a positive impact on the world, he said. “You don’t necessarily know [great leadership] when you see it in advance, but you’ll sure recognize it when you see it in action,” he said, humorously pointing to a 1978 photograph of Microsoft Corp.’s founders, which included a boyish-looking Bill Gates. Humor may have peppered his talk, but Augustine was serious as he discussed the challenges, particularly ethical ones, faced by leaders in today’s world. Honesty is always the best policy, he said, even when it has shortterm negative repercussions. He told of a time at Lockheed when he received an anonymous envelope containing a competing company’s upcoming bid for a major contract. He informed the competitor and refused to alter his own bid, which ultimately lost. People always face difficult decisions with incomplete information and conflicting advice, he said. Whether they become great leaders depends on how they rely on their own skills, and the talents of others, to rise to the occasion. “Often, the difference between victory and defeat is very small,” Augustine said. —HP eQ N E W S Faculty News Go East, say entrepreneurs at panel on India American entrepreneurs and venture capitalists should cast their eyes toward India, Princeton graduates Randolph Altschuler ’93 and Sumir Chadha ’93 said in a panel discussion Oct. 25. Altschuler, co-founder of the outsourcing company Office Tiger, and Chadha, senior managing director of Sequoia Capital India, painted a picture of the Indian economic landscape that was optimistic, but tempered with the realism of hard experience. “It’s almost like every sector is booming,” Chadha said, though he warned of pitfalls hidden in the “huge amount of economic optimism” that has taken India by storm. The event, “Creating New Ventures in India: Experiences, Opportunities and Challenges,” was part of a Technology Entrepreneurship Series co-sponsored by Princeton’s Center for Innovation in Engineering Education and the Jumpstart New Jersey Angel Network. It was moderated by engineering professor Ed Zschau ’61, who teaches the University’s popular hightech entrepreneurship course. Former roommates at Princeton, and later classmates at Harvard Business School, Altschuler and Chadha shared similar thoughts on business in India, despite having taken different approaches to the market. Altschuler, who majored in German literature, co-founded Office Tiger in 2000 with classmates Joseph Sigelman and Ravi Srinivasan. Chadha, a computer science major, plunged into the country that same year as a venture capitalist. The forward-thinkers were among the first to realize the possibilities in outsourcing to India, but their successes did not always come easily. “The infrastructure in India is still pretty poor,” Altschuler said. “But you can build your own infrastructure much easier [now than six years ago].” Both Office Tiger and Sequoia are battling high turnover rates among employees, and dealing with the Indian government is a challenge, the panelists said. Furthermore, labor and real estate costs have skyrocketed in Bangalore, Delhi and Bombay, leading many companies to set up shop in smaller, less-developed cities. These challenges notwithstanding, Altschuler and Chadha said that taking advantage of the business opportunities in India­­—from coffee shops to accounting services to software design—will help, rather than hurt, individual companies and the U.S. economy as a whole. “I actually think it is going to make us much stronger,” Chadha said. “It creates new markets and new opportunities as the Indian markets develop.” Improved telecommunications also are extending business opportunities to many other parts of the globe, including rural parts of the United States, said Altschuler. The entrepreneurship series will continue early next year, date to be announced, with an Innovation Forum where Princeton scientists and engineers will present research with commercial potential to an audience of students, entrepreneurs and investors. —HP Sumir Chadha ’93 shares insights on entrepreneurship and venture capitalism in India with interested audience members following an Oct. 25 panel discussion at Princeton.

Billington explains the mechanics of a suspension bridge with the help of a model built out of K’nex toys and simple supplies from a hardware store. The bridge is part of a laboratory created by Michael Littman, professor of mechanical and aerospace engineering and Billington’s collaborator for the “Engineering in the Modern World” course. It allows students to do quantitative experiments with three-dimensional models of structures studied in class. by Teresa Riordan Photo by Denise Applewhite David P. Billington ’50 is well known for connecting engineering to other disciplines within the University—to the humanities, art, science and politics. His courses in “Structures and the Urban Environment” and “Engineering in the Modern World” combine the study of engineering with an exploration of the aesthetic and social values intrinsic to it, an association of ideas that have made them some of the most popular courses among engineering and non-engineering students for decades. Billington, the Gordon Y.S. Wu Professor of Engineering, has taught perhaps 5,000 Princeton undergraduates since joining the faculty in 1960. “It would have never occurred to me to make these kinds of connections if I had not been at Princeton,” said Billington. “I don’t think it would have been possible at other universities to have such long and fruitful conversations with other disciplines. But I was able to do it here because of the University’s relatively small size and because the engineering school is so integral to the University itself.” Billington’s latest project is a book that provides an accessible account of eight breakthrough innovations that transformed American life from 1876 to 1939. He and his son, historian David P. Billington Jr., collaborated to write “Power, Speed and Form: Engineers and the Making of the 20th Century,” published this month by Princeton University 10 eqn Winter 2006–07 Press. The authors provide short narrative accounts of each breakthrough to explain the engineering behind the innovation and to describe how its innovators thought. On Oct. 27, he and his son were keynote speakers in San Diego at the annual conference of the National Academy of Engineering’s Center for the Advancement of Scholarship on Engineering Education. Billington has earned numerous honors for his scholarship and his teaching, including three Engineering Council awards. When Billington received the President’s Distinguished Teaching Award in 2001, one former student praised him as “the best instructor, the most inspirational adviser, and the professor with the most lasting impact on my interests and thinking.” In 2003, he received the National Science Foundation Director’s Award for Distinguished Teaching Scholars. In a recent conversation, Billington spoke about the beauty of engineering, his approaches to teaching and how Princeton has changed in the past 50 years. Why did you and your son write the book? The book grows out of my class “Engineering in the Modern World,” which I teach with Michael Littman [professor of mechanical and aerospace engineering]. It is often the largest course offered by the engineering school, and it draws engineering and liberal arts students alike. All of my scholarship grows out of this introductory course and two similar ones, and it feeds into those courses. I think of every lecture as a peer-reviewed publication. The idea of the book, which is a follow-up volume to my 1996 book “The Innovators,” is to focus on individual people and to differentiate between true innovators and mere inventors. The difference is that an inventor takes out a patent on a specific invention. There are hundreds of thousands of inventors but many fewer innovators. An innovator in private industry brings an invention to market so that it has a place in the market economy, while an innovator in public works designs a new type of structure that has widespread impact. There are two types of innovations. One type is an improvement on something that already exists. Then there are radical innovations, which truly change the culture. The telephone and the radio were radical innovations. The cell phone is less so because it is basically an improvement on existing innovations in wireless and the telephone. I don’t denigrate the more gradual kind of invention; it’s just that the other kind is more interesting to teach in an introduction to modern engineering. Do these innovators share certain characteristics? I’m naturally suspicious of general theories of innovation. Each one of these individuals is unique. But I would say they share a strength of character and an ability to think independently. For big thoughts, thinking alone is usually the most productive approach. But such engineers can only be successful in a technologically strong culture and usually with a group of talented people as assistants. You have been an innovator yourself in the field of engineering education. I’m trying to break out of the tradition of the standard way of introducing engineering. Technological literacy should be part of the liberal arts. Our life is an artificial world, and everything in our life is bounded by the built environment. I want my students to be equipped to see and interpret in an educated way the engineered environment that surrounds them. On the other hand, I would like engineers themselves to be more imbued with the history of their profession. If you ask most engineers, “Who are the greatest engineers of the 20th century?” you will often get a blank look. The engineering field is forward-looking and with good reason. But the future is always an outgrowth of the past. You can’t grow from nothing. What innovations do you cover in the book? Alexander Graham Bell’s telephone, Thomas Edison’s light and power network, oil refining breakthroughs, the automobile, the airplane, the radio, large-scale steel bridges and concrete structures, and the streamlining of automobiles and airplanes in the 1930s. One of my favorite innovations is William Burton’s idea for obtaining gasoline from crude oil. Standard Oil began using the method in 1913, about the time that Henry Ford perfected his mass-production system for making automobiles. Burton’s process vastly increased the amount of gasoline that could be produced from a barrel of crude oil and therefore had a tremendous but frequently overlooked role in the ascendancy of the automobile and in the more efficient use of natural resources. Who are your favorite innovators? In personal terms, I would say that Orville and Wilbur Wright were such stellar people that they come across very well. If we were just writing hagiography, it would not be nearly so interesting. These were real people. They were flawed and stubborn but possessed brilliant insight as engineers. Samuel Morse and Henry Ford could be nasty. You don’t have to revere them to respect their innovations. You have said that innovators are very different from scientists. How? Unlike a scientist whose goal is discovery, the goal of engineers is to design new objects or systems. [Samuel] Langley, the head of the Smithsonian, approached the problem of flight as a scientist, and he was unsuccessful. The Wright brothers focused on full-scale testing and relatively simple mathematical formulas to design their pioneering airplane. All the innovations we explore used relatively simple numerical ideas. Our book is unique in that we gently weave these mathematical concepts into the narrative accounts of each breakthrough. You have revamped your spring structures course. Why? Because the course already deals with the urban environment, we want to expand the material covered to include such things as the Big Dig in Boston and New Orleans in the aftermath of Hurricane Katrina. To make room for all this new material, we have radically simplified the emphasis on calculations, so the course should appeal to all students. Kenneth Condit, who [when I was an undergraduate] was the pioneering dean of the School of Engineering, had invented an academic program called Basic Engineering. It was for generalists rather than specialists. I took a wide range of engineering classes and had more electives than the liberal arts students did. My “Engineering in the Modern World” course is really a boiled down version of that whole program. When did you come back to Princeton to teach? After I graduated I won a Fulbright fellowship and went to study in Belgium, where I was exposed to a lot of innovative work in pre-stressed concrete. This made me valuable when I got back two years later to the United States, which was behind in this field. I worked in New York designing structures for a consulting engineering firm. In 1958 I was invited to teach a night course at Princeton, and two years later I joined the faculty. Although you are not formally trained in history, you and your brother, Librarian of Congress James H. Billington ’50, are both historians. Was history highly prized in your family growing up? My father really should have been a history professor. But when he was 14 his father died, and he had to support the family; he ultimately became an insurance broker. Jim fulfilled his ambition. In another era our mother would have been an engineer; her father was an engineer, and she was very good in math and science. Instead she became a home economist and was the cooking editor of the Curtis Publishing Co. and helped to found Jack & Jill magazine. We grew up middle-middle-class outside of Philadelphia in Merion, Pa. Our parents lost all their money in the Depression. We had a truly wonderful upbringing in that it was not privileged. We hardly went anywhere in the summer. We were a close little family. It was very happy but not consciously intellectual. Jim and I loved comic books; we had a huge collection that we would loan out to our friends. And now your son David Billington Jr. is a historian too, working as an independent scholar. What was it like to work together on this book? David has described our work together as a collaboration in which each has learned from the other. I think that is absolutely correct. I grappled with this book for 10 years and then turned it over to him. David’s contributions changed the focus of the book to emphasize some important new themes. In some ways, this is perhaps more his book than mine, which is particularly impressive given that at the same time he was completing a significant book on modern British history that was also published this year. Now that this book is finished, what lies ahead for you? One principal challenge now for me is to ensure that the teaching of engineering becomes a significant part of the liberal arts curriculum at Princeton and that all engineering students gain an understanding of the grand tradition of modern engineering. A vital way to meet this challenge will be to educate, through my graduate program, a new kind of teacherscholar. These students will learn how to do first-rate structural engineering scholarship during the course of their doctoral work; they will also teach in introductory courses and their research will in turn enrich these courses. Then, as exemplars of this teacher-scholar model, the students will carry this tradition forward as they take positions in other colleges and universities.

He has created a community of colleagues who support and inspire each other’s research, including Massey’s own. “His mentorship is more than just oneon-one,” said Otis B. Jennings, a member of Princeton’s class of 1994 who is now an assistant professor at Duke University’s Fuqua School of Business. “It’s sort of a meta-mentorship,” said Jennings, who was advised on his senior thesis by Massey. “He creates the environment where people can make connections for mutual benefit. As a mentor you may help someone get a Ph.D.—but in the end you have a new colleague. And Bill is building a family of colleagues.” On Nov. 3, Massey, the Edwin S. Wilsey Professor of Operations Research and Financial Engineering and a 1977 Princeton alumnus, received the Blackwell-Tapia Prize at the Institute for Mathematics and its Applications in Minneapolis. The prize is in recognition of his outstanding record of achievement in mathematical research and his mentoring of minorities and women in the field of mathematics. In a tribute to Massey’s distinguished career as a pioneer in the field of applied mathematics called queueing theory, the institute has organized a two-day conference on topics related to Massey’s research. In addition to Jennings, minority and women Princeton alumni Massey has mentored include Andrea Bertozzi, a 1987 undergraduate and 1991 graduate alumna who is currently a full professor in mathematics and director of applied mathematics at the University of California-Los Angeles; Arlie Petters, who Right: Massey (foreground) gathered with some of the people he has mentored over the years, including (from left) Robert Hampshire, a current graduate student in operations research and financial engineering who will join the faculty at Carnegie Mellon this spring; Arlie Petters, a graduate student from 1988 to 1991 who is now a professor of mathematics and physics at Duke University; and Otis Jennings, a 1994 undergraduate alumnus who is now an assistant professor in the Fuqua School of Business at Duke University. Below right: Otis Jennings ’94 Photos by Steve Exum “His mentorship is more than just one-on-one. He creates the environment where people can make connections for mutual benefit.” – Otis Jennings ’94 attended Princeton as a graduate student from 1988 to 1991 and is now a full professor of mathematics and physics at Duke University; and Robert Hampshire, a current Princeton engineering graduate student who will begin a teaching position at Carnegie Mellon University in the spring. Massey, the first African-American Princeton undergraduate to have become a full professor at the University, also founded and continues to provide leadership for the annual Conference for African American Researchers in the Mathematical Sciences, now in its 12th year. Playing with numbers Massey grew up in St. Louis, the son of a high school counselor and a home economics teacher. He loved numbers as a small child, and his mother playfully encouraged his talent by cutting up calendars for him and creating games. His mathematical abilities became fully manifest in a predominantly black public school for gifted students, and later in high school. When it was time for college, his parents brought him east to visit Harvard, MIT and Princeton. “It certainly helped having parents who were educators,” said Massey. “They were encouraging of me wanting to do mathematics. At the time, I didn’t know that other black people even worked in math.” Massey remembers his own mentors as an undergraduate at Princeton with great fondness: mathematicians W. Stephen Wilson, Ralph Fox and Bernard Dwork; and physicists Cyrus Hoffman and Aaron Lemonick. “I was lucky in who taught me,” said Massey, who remembers that Wilson advised him to do something non-intuitive when he arrived at Princeton. “I saw myself as a math major and had placed out of freshman math,” Massey recalls. “Wilson told me to go ahead and take a freshman honors-level calculus class but sophomore-level physics. This turned out to be the best advice I could have gotten because I had been for the most part self-taught in math. [By taking the calculus class] I learned that my understanding of math was really cookbook mathematics; I was familiar with various formulae and how to manipulate them but not with the more sophisticated understanding of how to prove theorems.” Massey said that an early course with Lemonick imbued him with a love for physics. “I was thinking I didn’t want to be that involved in physics but he actually got me excited about it. So rather than thinking of it as fulfilling a requirement, I took physics throughout my four years.” Graduating magna cum laude and Phi Beta Kappa with a degree in mathematics, Massey continued on to graduate school in mathematics at Stanford University, earning his Ph.D. in 1981. While at Stanford, he became friends with Erhan Çinlar, who was then at Northwestern University and is now Princeton’s Norman J. Sollenberger Professor in Engineering. Çinlar, who will be delivering the plenary address at the conference in honor of Massey, tried to hire Massey right out of graduate school but Massey demurred. He instead went to Bell Labs, then in its heyday as one of the nation’s premier research institutions, and stayed for 20 years. Creating a legacy Massey credits his time at Bell Labs with fostering innovative research but also creating an environment that allowed minorities to flourish. He had first worked there his summer after he graduated from Princeton, and felt inspired by the sizable cadre of black scientists. “Bell Labs of the 1970s, ’80s and ’90s was to black scientists what Harlem of the 1920s was to black writers, artists and musicians,” said Massey. “It was a true renaissance.” Massey was in the mathematical sciences research center but rubbed elbows with researchers in electrical engineering and physics and many other fields. On a given day he might have bumped into Jim West, co-inventor of the modern day microphone, and then the next minute have run into the physicist Shirley Jackson, now president of Rensselaer Polytechnic Institute. “There was no shortage of black individuals who were high-achieving in their respective fields,” said Massey. “But they were also dedicated collectively to creating a legacy for the next generation.” Massey said that his mentoring philosophy grows out of the Bell Labs approach — and out of the notion that small steps cumulatively will lead eventually to momentous change. Bell Labs hired its first African American scientist, W. Lincoln Hawkins, in 1942 but it would be 20 more years before it hired another African American researcher. By the time Massey first worked there, Bell Labs had a critical mass of black scientists. “We see what happened at Bell Labs with Lincoln Hawkins,” said Massey. “Imagine what could have happened at Princeton or any other research institution for that matter” if someone of Hawkins’ stature had been hired back in the 1940s. Massey, his protégés say, may well become to Princeton what Hawkins was to Bell Labs: a fulcrum that tips the institution into becoming a mecca for African American scientists. “The more soldiers you have, the more soldiers you can train,” observed Jennings. (Continued on page 14) eqn Winter 2006–07 13 “Bill always coupled his mentoring with a lot of mathematical discourse. It created an ideal setting for addressing a variety of ideas and techniques. I enjoyed those grad school days largely due to his mentoring style.” (Continued from page 13) Massey and his protégés Bertozzi, Jennings, Petters and Hampshire all received graduate school funding from Bell Labs fellowships. Massey served as a mentor in the Bell Labs fellowship programs for minorities and women—the same programs in which he participated as an undergraduate. He conducted joint research with students funded by these programs over the summer, publishing seven papers with students as co-authors. In addition, he included his students as speakers at telecommunications conferences. Queueing up Çinlar, who came to Princeton in 1985 and served as the founding chair of the Department of Operations Research and Financial Engineering, continued his efforts to tempt Massey back into academia for two decades. Finally, in 2001, Massey relented and came to Princeton as a full professor. “One thing I learned from my experience with Bill Massey is that you have to keep after valuable people,” said Çinlar. “You have to pursue them over quite a long period of time and get used to being spurned.” At Bell Labs, Massey had begun to make his mark in queueing theory by analyzing it from a dynamic rather than a static point of view. At Princeton, he has continued that research and has taught courses in queueing theory and Monte Carlo simulations. Queuing theory is a key mathematical tool used to solve many problems of providing communications services, from the old-fashioned telephone service to Internet phenomena like Napster and YouTube. The success of a business model for a wireless telephone provider, for example, might hinge on how efficient that provider is at applying queueing theory. “Even simple queuing theory involves a lot of complex mathematics and statistics, and understanding the type of queuing systems that arise in modern communication systems requires new mathematics and new analysis,” said Douglas Arnold, director of the Institute 14 eqn Winter 2006–07 – Arlie Petters *91 for Mathematics and its Applications and an organizer of this year’s Blackwell-Tapia Conference at which Massey received his award. “This is where Bill Massey has made outstanding contributions.” A much cited paper of Massey’s showed how to create a mathematical description of wireless networks in which calls are being placed and received from moving vehicles. In 2005, The Journal of Blacks in Higher Education named Massey the second most frequently cited black mathematician in the world. Massey also has a patent on an optimal server staffing algorithm for call centers that is based on his research in queueing. Three days after receiving the BlackwellTapia Prize, Massey (along with Robert Vanderbei) were inducted as a fellow of the Institute for Operations Research and the Management Sciences—an honor accorded to fewer than 1 percent of the institute’s membership and made in recognition of significant research contributions. Coming full circle In addition to carrying on his research from Bell Labs, Massey has built upon the mentoring efforts he began there. He has served as a board member for the National Association of Mathematicians, a mathematics organization for underrepresented minorities, and has hosted its annual presentations by doctoral recipients that provide students with an opportunity to showcase their research at a major international conference. “Bill always coupled his mentoring with a lot of mathematical discourse,” said Petters, who moved on to MIT after three years of graduate work at Princeton and earned his Ph.D. there. “It created an ideal setting for addressing a variety of ideas and techniques. I enjoyed those grad school days largely due to his mentoring style.” Massey also has been an active participant in the Blackwell-Tapia Conference, held every other year in honor of David Blackwell and Richard Tapia, two mathematical scientists who inspired many African American, Latino/ Latina and Native American mathematicians. In receiving the third biennial Blackwell-Tapia Prize at this year’s conference, he follows in the footsteps of Petters, who was the first recipient of the prize in 2002. During the 1980s and 1990s, Massey was also a driving force in the Association of Black Princeton Alumni. “The reason ABPA is one of the best organized and largest affinity groups among Princeton alumni is due in part to his legacy,” said Jennings. Massey served as moderator of a panel discussion about careers in academia at Princeton’s recent “Coming Back and Looking Forward” conference for black alumni. One former Princeton student who attended the Princeton conference described Massey’s mentoring as a kind of “tyrannical affection.” “If Bill takes a liking to you, you are in for a rigorous friendship,” he said. Jennings acknowledged that Massey can be tough on the people he mentors. “Bill holds himself to a very high standard and if you are going to do business with him you had better hold to that standard as well. Bill likes to brag that I had never worked hard until I met him. He is a refreshing combination of brilliance, perseverance and concern for others.” But, Jennings emphasized, Massey is in the business of creating peers, not acolytes. “As I mature as a researcher my appreciation of Bill continues to grow,” said Jennings. “I have always been able to confide my research dreams and aspirations to him. But our relationship has experienced an evolution. Now I have an independent perspective that I hope he benefits from as much as I benefit from his insight. We have come full circle.” Engineers, scientists and policy experts join forces to solve energy and climate problems 7 Wedges are needed to build the stablization triangle 14 dic avoids one billion tons of carbon emissions per year by 2054 re tp n rre Cu 1 Wedge 7 ath p ted Stabilization Triangle Flat path Practically every activity of every human being every day contributes to perhaps the most dramatic experiment ever conducted—what happens to life on Earth if the atmospheric concentration of carbon dioxide gas triples? Any action that consumes fossil fuels or changes land use plays a role in the current human pattern of transferring billions of tons of carbon from plants and the ground into the atmosphere each year. At the current rate, the percentage of atmospheric carbon dioxide gas will triple during this century from pre-industrial levels. The general effect of this change appears to be that the planet gets warmer because carbon dioxide traps the sun’s heat. The specific consequences still are being determined but appear to include loss of polar ice, coastal land areas, coral reefs and biodiversity, changes in ocean circulation and weather patterns, and increases in disease propagation. The complexity of understanding, monitoring and, ultimately, controlling this experiment is staggering. Each aspect requires close interaction among scientists, policy-makers, engineers and business leaders. Building on these connections forms the basis of Princeton Engineering’s strategy for helping to manage the carbon experiment. “We are taking a big-picture approach to this problem,” said H. Vincent Poor *77, dean of engineering. “We are working ever more closely with our colleagues in the natural sciences and public policy to develop a coordinated approach and go after the big questions, including the fundamental technologies that need to be in place to move forward.” This approach already is making a difference. In 2004, Stephen Pacala, professor of ecology and evolutionary biology, and Robert Socolow, professor of mechanical and aerospace engineering, teamed up to publish a landmark paper in the journal Science outlining what could be done to hold global carbon emissions steady for the next 50 years, thus keeping the atmospheric concentration of carbon dioxide on track, with further effort, to stay just below double pre-industrial levels. Their paper, which divides possible solutions into easy-to-understand “wedges,” quickly became a standard way of describing the problem and is referred to at practically all climate conferences. (Continued on page 16) 2004 2054 14 Billions of Tons of Carbon Emitted per Year Toward tripling d nt re ur te dic th pa e pr C 7 Historical emissions 1954 Avoid doubling 2004 2054 The “wedges” paper by Pacala and Socolow describes two possible futures: the current path of growing carbon emissions and an alternative path on which emissions stay flat for 50 years. The difference between these paths is small in the first years, but grows to 7 billion tons of carbon a year by the 2050s. The paper looks at how to avoid those added carbon emissions and breaks the challenge into seven 1-billion-ton “wedges.” The authors provided extensive analysis of 15 existing technologies, any seven of which could be selected à la carte and scaled up to create the necessary wedges. eqn Winter 2006–07 15 (Continued from page 15) “The wedges concept has become the iPod of climate policy,” said David Hawkins, director of the Climate Center at the National Resources Defense Council. “By designing an attractive and recognizable package, Pacala and Socolow have provided the climate community with a versatile and accessible tool that helps clarify the murky subject of reducing greenhouse gas pollution. Like the iPod, the wedges image is a versatile container that different users can fill with their favorite ideas on how to fight global warming.” Pacala and Socolow are co-directors of the Princeton Environmental Institute’s Carbon Mitigation Initiative, a 10-year venture funded in 2000 by BP and Ford. The initiative, which exemplifies Princeton’s multidisciplinary approach, seeks to understand and develop solutions for the carbon problem. In the following pages, EQuad News presents three examples of research projects within Princeton Engineering, each of which could contribute a wedge or more of climate solutions. Much of this research receives funding through the Carbon Mitigation Initiative as well as from the National Science Foundation, the Department of Energy and other sources. A fourth project presented here improves the prospects of nuclear fusion, a safe and clean energy source that may become crucial in the second half of the century. In addition to contributing to these technological solutions, Princeton engineers are advancing the techniques and devices needed to improve fundamental climate science. Civil and environmental engineer Professor Eric Wood, for example, is developing hydrological models that feed into scientists’ overall understanding of how water, land and air interact. In the same department, Professor James Smith is part of Princeton’s newly established MIRTHE center for mid-infrared sensors and is developing technology that could better monitor greenhouse gasses in the atmosphere. This rich collection of expertise positions Princeton to be the leading institution in the world for dealing with the overall climate problem, said Pacala, who directs the Princeton Environmental Institute. Strong programs in engineering, science and public policy combine with the presence at Princeton of two important national labs: the Princeton Plasma Physics Lab, which is the nation’s first research center for nuclear fusion, and the Capturing carbon Studies test safety of sequestration Burning oil and coal, which are rich in carbon, releases the greenhouse gas carbon dioxide. Until alternative fuels become mainstream, one viable option to cut carbon emissions is to capture the gas and inject it into sediments deep underground, according to Princeton’s Michael Celia *79, chair of civil and environmental engineering. However, the technology will only succeed if the gas stays safely stored for hundreds, even thousands of years. Celia and colleagues in his department are trying to make sure that it does. Old oil and gas fields would be convenient sites to inject and store captured carbon dioxide, but the old wells also create potential routes for the gas to escape. “A typical injected CO2 plume may encounter tens to hundreds of these existing wells,” Celia said. Working with the Alberta (Canada) Geological Survey, Celia is developing large-scale 3D 16 eqn Winter 2006–07 models to simulate how the gas might move, interact with the wells and potentially leak. Professor Jean Prevost is also simulating the behavior of injected CO2, predicting how carbonic acid formed by the CO2 will degrade the cement used to plug old wells. Professor George Scherer is conducting laboratory experiments to answer the same question, while associate professor Catherine Peters is studying the structure and mineral composition of rock samples from Alberta to understand how they react with carbonic acid. So far, their conclusions are mixed: in many cases the acid cannot eat through rock or cement to reach the surface, but in situations where the cement already has defects, the acid can enhance the damage and lead to CO2 leakage. These results could influence the development of regulations and permitting criteria for large-scale injection operations, Celia said. —Prachi Patel-Predd Geophysical Fluid Dynamics Lab, which is one of the most important climate modeling centers in the world. The payoff for reducing carbon emissions goes beyond slowing climate change. Pacala and Socolow noted that a technology designed to solve that one problem often will eliminate other forms of pollution, including smog and acid rain, and increase U.S. energy independence, thereby improving national security and easing global tensions. “It’s an example where you solve multiple societal problems by inventing a technological solution to solve one,” Pacala said.—Steven Schultz Below: Carbon dioxide injected underground forms strong carbonic acid, which could eat away some minerals, possibly allowing the gas to escape. Researchers led by Prof. Catherine Peters have devised an imaging technique and color processing scheme to quantify how vulnerable typical sandstones are to acid attack. The gray color represents quartz, which is not reactive; the mildly reactive green-labeled minerals tend to surround the open pores, obscuring access to the reactive red minerals. Reducing emissions Deeper understanding of combustion improves efficiency Eighty five percent of the world’s energy supply comes from burning fossil fuels, and this will most likely be the case for a few decades, according to assistant professor Yiguang Ju. In Princeton’s mechanical and aerospace engineering department, Ju and Professors Frederick Dryer and Chung K. Law are making the best of that reality by studying the combustion of conventional and alternative fuels to harness their energy with maximum efficiency. Their understanding could lead to the best possible burning methods, improved engines and the safe use of hydrogen as a fuel. These researchers, for example, are studying the burning and emission properties of dimethyl ether and syngas, synthetic fuels that can be derived from coal or biomass. Syngas could drive power plant turbines, generating less particulate pollution and mercury than coal. “If you make syngas from biomass and then sequester the CO2, you could negate overall CO2 emissions,” Ju said. But controlling the ignition and combustion of syngas can be difficult, a problem that Ju is tackling in research funded by the U.S. Department of Energy and the American Chemical Society. Above right corner: Right: To understand how hydrogen burns in the highpressure environment of internal combustion engines, Law and his student Grunde Jomaas took high-speed movies of the expanding flame after the mixture had been ignited by a spark. Increasing the chamber pressure caused profuse wrinkles to develop over the flame surface; the increased surface area leads to a greatly increased burning rate. Spiral waves were also observed. In an upcoming Combustion Science and Technology paper, researchers led by Prof. Fred Dryer show that, contrary to previous assumptions, hydrogen can spontaneously ignite if a storage vessel ruptures and the geometry of the space outside the rupture is right. Fanning flames with water Fuel cell research makes most of moisture Fuel cell batteries might power clean cars of the future, but for now they are found in niche applications such as spacecraft, where cost is no object. “We are trying to figure out how you could build fuel cells that operate more simply and are cheaper to produce so that they would be acceptable in a consumer market,” said Princeton professor of chemical engineering Jay Benziger. Fuel cells can be thought of as chemical reactors in which hydrogen and oxygen combine, generating electricity and water. Benziger works with polymer electrolyte membrane (PEM) fuel cells, which are said to hold the most promise for transport applications. To operate, PEM cells need water, which Power (W.com ) 0.5 Dimethyl ether, a diesel and cooking fuel substitute, emits low amounts of nitrogen oxide and no soot, he said. In another project, he is collaborating with researchers at China’s Tsinghua University to examine the impact on nitrogen oxide emissions when ethanol is added to gasoline. Ju’s work could slash the emissions from dimethyl ether and ethanol, benefiting their use in China and other developing countries.—PPP is provided by an auxiliary humidification system. In a landmark finding, Benziger has determined the optimum amount of water in the membrane that sustains the cell’s chemical reactions. By understanding this and other key mechanisms of a fuel cell reactor, his research group has improved the system’s design. They have made a new reactor that eliminates the hardware and cost of humidification equipment. Instead, it uses the water produced by the fuel cell reaction itself. They are now developing new, less expensive polymer materials for the membranes. “There are still major obstacles to dramatically reduce cost and increase reliability that must be solved before fuel cells can compete with modern combustion engines,” Benziger said.—PPP 0.45 0.4 0.35 0.3 0.25 0.2 Left: Conventional design– auxilliary humidification 0.15 0.1 0.05 Improved design– automatic humidification An improved fuel cell design from the lab of Prof. Jay Benziger allows simpler construction and operation a higher current densities than conventional designs.

A new ultrafast laser offers hope As an ultrashort laser pulse travels through a collection of hot ionized particles known as plasma, another longer and less intensive laser pulse amplifies it as much as 1,000 times to an intensity of 200 petawatts per square centimeter. It also compresses the pulse to a duration of a few dozen femtoseconds (quadrillionths of a second). Nuclear fusion promises clean, unlimited energy, of the sort created by the sun. But making a practical reactor is difficult and expensive. In one approach, called inertial fusion, scientists bombard a tiny pellet of deuterium-tritium fuel with intense laser pulses to kick off the fusion reaction. The problem, said Princeton mechanical engineering professor Szymon Suckewer, is that this technique requires large lasers that come with equally large price tags—billions of dollars. One leading idea to make fusion more efficient is a two-laser system that ignites the fuel pellet in steps. Suckewer is developing an extremely powerful, compact laser that could greatly reduce the cost of the first step. His laser exploits the properties of plasmas—hot ionized particles—to transfer energy from one laser into another, producing pulses that deliver an enormous amount of power (on the order of petawatts, or 1015 watts) in ultrashort bursts measured in femtoseconds. In addition to reducing the cost of fusion, the new laser could lead to a practical x-ray laser, a long-sought tool for microscopy and for manufacturing ultra-small devices, including computer chips.­—PPP Collaboration with start-up company improves efficiency of solar power Professor of Electrical Engineering Sanjeev Kulkarni (center) and Assistant Professor of Mechanical and Aerospace Engineering Clancy Rowley ’95 (far left) are collaborating on a solar energy project with Princeton Power Systems founders (from left) Erik Limpaecher ’01, Mark Holveck ’01 and Darren Hammell ’01.

Princeton Power Systems, a company started in 2001 by three freshly minted Princeton engineering graduates, received a grant from the New Jersey Commission on Science and Technology to conduct joint research with the School of Engineering. The company’s technol- Meng ’05 combines interests to confront environmental problems in China By Hilary Parker Whether in Princeton, Beijing, New York or Nairobi, there’s a certain continuity to the work of Kyle Meng ’05. After winning the University’s coveted Martin Dale ’53 Fellowship, which annually provides $25,000 to support a senior’s yearlong post-graduation project, Meng spent nine months in China exploring the Chinese perceptions of their environment. The project had its roots in the research Meng did for his senior thesis in civil and environmental engineering, “Identifying Opportunities for Carbon Capture and Storage Demonstration Projects in China.” As he gathered data at the Tsinghua-BP Clean Energy Research and Education Centre in Beijing the summer after his junior year, he became aware of significant cultural and political roadblocks to China’s burgeoning environmental movement. His Dale project, “Unearthing the Dragon: Understanding How the Chinese Perceive Their Environment,” merged his knowledge of environmental issues with his certificate in environmental studies and interest in public policy. Based at the Tsinghua University School of Public Policy in Beijing, Meng took an interdisciplinary approach to his self-declared mission. Through surveys of 900 Chinese un- dergraduates, interviews with environmental activists and weeks of library research, he immersed himself in the history and culture of the country where he lived until he was 6 years old. “I was really just so impressed by the environmentalists in China,” he said. “As a foreigner, I was able to tap into this community and I met some remarkable individuals.” He told some of their stories in freelance articles written for publications including The Environmental Forum, the Environmental Law Institute’s policy journal. One article described a poor farmer in the Hebei province who profited from single-handedly reforesting a 600-acre swath of land. Meng’s goal, he said, was to “tell the whole story,” going beyond statistics and figures to spread an important message. “In China, it is possible to meld economic and environmental benefits,” he said emphatically. “[The Hebei farmer’s] story has become a model to a lot of villagers in his area.” While current events are important, Meng said that true knowledge of Chinese attitudes toward the environment requires an understanding of the interplay between traditional philosophies and the modern communist ideology. He recently submitted a paper on the subject to China Quarterly. “It was certainly a very important learning process for me,” Meng said of his time in China, noting that the “no strings attached” nature of the fellowship allowed him the chance to modify his project over time to meet his goals. Now a High Meadows Fellow, supported by Princeton’s Pace Center, Meng recently began work with the New York-based Environmental Defense on the group’s Climate and Air Program, specializing on China. He constantly relies on the quantitative and multidisciplinary problem-solving skills he honed at Princeton in his new position, he said. From Nov. 6 to Nov.17, Meng turned once again to the subject of his thesis research as part of the Environmental Defense delegation to the United Nations Climate Change Conference in Nairobi, Kenya, where he addressed issues relating to China. With an eye toward graduate school, Meng said his future focus will be on China and the environment, but he doesn’t yet know from what perspective. “At the moment, I’m not sure which discipline I want to specialize in,” he said. “But these are complicated environmental problems, ones that will require an interdisciplinary approach. My task in these two years is to find the discipline that will allow me to most effectively tackle these problems.” ogy transfers electricity from the solar panel to the public electric grid more efficiently than other systems, allowing peak performance during less-than-optimal sun conditions. “Most people think of solar panels as being passive,” said Darren Hammell, who is chief executive officer of Princeton Power, which he cofounded with Erik Limpaecher and Mark Holveck, all members of the class of 2001. “But we can actively control them to optimize their efficiency in response to changing environmental conditions.” Hammell noted that most studies of solar power have been done in sun-saturated states like California and Arizona. “New Jersey is in many ways ideal for solar power because of a good state rebate program and high energy prices,” he said. “But no one has really studied how solar power can be optimized in New Jersey.” For one thing, of course, New Jersey has a lot of clouds. This means that in order to maximize the power harvested from the panels, the inverter needs to tweak both the voltage (the capacity to produce electricity) and the current (the flow of the electricity) so that both run optimally in an on-the-fly response to changing sun intensity.

Not just any box, but rather a solar-powered oven she designed her freshman year with classmate Lauren Wang, under the guidance of Wole Soboyejo, professor of mechanical and aerospace engineering. Powered by the sun’s energy and constructed with locally available materials, the ovens can be built and used in Third World nations, thereby allowing development while preserving the environment and local economies. In many communities, the ovens could slow deforestation that results from harvesting wood for cooking fires. “Coming to Princeton, I was expecting to be involved in projects that used engineering and did outreach,” Sud said, adding that the University’s emphasis on serving all nations was a key factor in her decision to attend. She fulfilled her expectations through her involvement with the Global Development Network, an extension of the U.S.-Africa Materials Institute directed by Soboyejo and sponsored by the National Science Foundation. “Ishani exemplifies the whole notion of Princeton engineering in service of the world,” Soboyejo said. “In just two years, she has worked within the Global Development Network family to change the lives of school children in Kenya and Tanzania, while pioneering new ways of solving basic problems of energy and water in the developing world.” Many factors led to Sud’s passion for science and community activism. The daughter of an environmental engineer and a geneticist, she was moved by the extreme poverty she encountered on childhood trips to her parents’ native India. “As a kid, when you see other kids that are suffering, your heart goes out to them,” she said. “You want to do something to make a difference.” She was similarly affected by the suffering she encountered in her hometown of Durham, N.C. As a participant in the Durham County Teen Court program to decide juvenile misdemeanor cases, Sud found herself faceto-face with peers who had shoplifted diapers for their newborn babies or stolen food they simply couldn’t get at home. 20 eqn Winter 2006–07 Ishani Sud (above), a junior chemical engineering major, spent part of last summer in Kenya and Tanzania teaching children and helping local people build solar ovens that she helped design under the guidance of Prof. Wole Soboyejo. She enjoyed enthusiastic receptions among children, including a group (right) who made pinwheels as part of a part of a lesson Sud helped teach on energy. The solar ovens (below), which reach at least 300 degrees in less than half an hour, could help prevent deforestation by reducing the need for firewood. Photos courtesy of Ishani Sud. Her scientific mind was honed in Durham, as well, at the North Carolina School of Science and Mathematics, a public boarding magnet school in Durham she attended for her junior and senior years of high school. Sud found an outlet for her expertise and empathy in Mpala, Kenya, where she spent six weeks the summer following her freshman year with classmate Julianne Davis. There, the two engineers worked with elementary and middle school students to build solar ovens with readily available materials, while teaching them about science, conservation and renewable energy. (Continued on p. 22) The landscape of central Kenya reveals some of the features of interest to Princeton researchers studying water dynamics, land management and wildlife. The deep channel above is a “headcut” caused by flash floods in which water rushes through and then evaporates quickly.

Clay McEldowney ‘69, Pinky McEldowney, Eric Hui, Anh-thu Ngo, Sebastien Douville, Gregory Redman, Andrew Lapetina and Sean McGowan. A flash flood swept away a dam built by the Princeton chapter of Engineers Without Borders this summer in its first attempt to irrigate fields around the village of Kumudo, Ethiopia. But it did nothing to dampen the volunteers’ commitment to their task. Mentored by civil engineer H. Clay McEldowney ’69, the nine students abandoned their effort to divert a river’s course and redirected their own efforts instead, devising a plan to install a siphon-pump system to provide muchneeded water to the arid land. The trip to Ethiopia was the second major project for Engineers Without Borders-Princeton. In the group’s first year, 2005, students built sanitary bathrooms in Huamanzaña, Peru. This year in Africa, after some quick rethinking, the engineers bought local supplies and laid nearly half a mile of PVC piping to carry water from a cistern near the river’s headwaters to a tank they built adjacent to the villagers’ crops. “The way EWB works is that it connects chapters with communities,” said Andrew Lapetina ’07, the chapter’s president. As community involvement is essential for the success of any project, Lapetina said he and his fellow students demonstrated siphonpump systems to gatherings of community members, many of whom volunteered their time and energy to the labor-intensive project. The entire system is now in place and should become operational when the Princeton chapter returns to Kumudo over winter break with the tools and priming pump needed to start the siphon action. The chapter has a similar ongoing relationship with the community in Peru. Everyone involved benefits from these ongoing partnerships, Lapetina said. Not only does the quality of life improve in the partner communities, but Princeton students broaden their minds and realms of experience. “Getting real-world engineering experience of this type at my age is a very unique thing,” Lapetina said. “And, living and getting in touch with the daily trials of people who live on less than two dollars a day, learning to live really simply, is something that’s really valuable.” —HP Initiative aims to improve water and land use in Africa Work combines engineering, ecology and public policy Princeton engineers are playing a leading role in a new initiative to improve the socioeconomic wellbeing of Kenyans by studying the interplay between water dynamics, land management and wildlife on the savanna. In August, Michael Celia, chair of civil and environmental engineering, and Daniel Rubenstein, chair of ecology and evolutionary biology, visited Mpala, Kenya, with graduate students to begin fieldwork. They and Ignacio Rodriguez-Iturbe, James S. McDonnell Distinguished University Professor of Civil and Environmental Engineering, will return to Kenya in early 2007 for a second round of fieldwork. “The long-term goal is to understand the central role that water plays in these semi-arid regions, as well as the pressures imposed on vegetation by both livestock and wildlife. If possible, we would like to avoid widespread degradation of the landscape,” Celia said. The Water, Savannas, and Society in SubSaharan Africa Initiative – directed by Celia, Rodriguez-Iturbe, Rubenstein and Professor of Political Science Jennifer Widner – is funded by the Princeton Institute for International and Regional Studies, with additional support from the Princeton Environmental Institute. The participants in the initiative are studying an area that is approximately 10 kilometers by 10 kilometers in central Kenya and which is a crossroads of important migratory pathways for elephants and zebras. The area is controlled by a half dozen different Masai tribes. (Continued on p. 22) Photos for this story by Trenton Franz eqn Winter 2006–07 21 PRINCETON ENGINEERING IN AFRICA ‘The dynamo’ (continued from page 20) They also hosted community days to teach residents how to cook local recipes, including the traditional African starch dish ugali, in the solar ovens. During her sophomore year, Sud worked with the Global Development Network to establish collaborations with universities in Third World countries, where resident faculty and students are better equipped to work with local people and are more in tune with their needs. This allows the Princeton students to deploy the programs they’ve developed, such as the solar oven, without requiring them to travel to every community. This past summer was a whirlwind for Sud, who met with researchers at universities in Brazil and Tanzania to share ideas on sustain- able projects, spent time in Kenya continuing the solar oven project and launched a similar program at the Aang Serian school for indigenous people in Monduli, Tanzania. During her travels she was joined by fellow Princetonians Viola Huang, Brandon Rogers, Patricia Li, Daniel Cohen and Julianne Davis and research staff member Michael Vocaturo. “This was a nice experience because it gave me a chance to learn about the community, give back, manage a project and learn about the actual science and research that goes into it,” Sud said. This year, “the dynamo,” as Soboyejo describes Sud, is organizing a group of students to research and design ceramic water filters built with basic materials, such as clay and plant matter. The students plan to test and analyze their designs before winter break and hope to spread the technology in outreach projects this summer. With seemingly limitless energy, Sud has done all of this while completing the requirements for her B.S.E. in chemical engineering, along with four certificate programs: materials science and engineering, the Woodrow Wilson School of Public and International Affairs, engineering biology and neuroscience. Faced with a challenging academic schedule—she’s taken at least five courses every semester at Princeton—she said her interest in the subjects and the camaraderie she finds in study groups help her handle the heavy load. “And, I tend to plan my time really carefully,” she added after a brief pause. She even makes room in her calendar to remain active with the Society of Women Engineers, serve as a residential college adviser in Butler College and this semester assist the investment and technology development firm D.E. Shaw with on-campus recruiting. “I enjoy these activities so I don’t think of them as work,” she said. Though Sud said she can envision many possible futures for herself, from pharmaceutical chemical engineering to public policy work, they share a common thread. “I want to be able to make a real difference in whatever community I’m working with or serving,” she said. Initiative aims to improve water and land use in Africa (continued from page 21) According to Celia, the region should yield important data because it is a patchwork of different kinds of lands, ranging from land that is strongly overgrazed and degraded, to land that is well-managed and productive. When they return to Africa in the spring, the participating engineers will collect data from watersheds—essentially small valleys—and study the effect of strong storms whose resulting rainfall causes large gashes in the soil known as headcuts. They also will study the interaction between different grass and tree species, to better understand vegetation dynamics. Other participants in the initiative are Trenton Franz and Alex Lester, graduate students in civil and environmental engineering; Elizabeth King, a postdoctoral researcher in ecology; Eva Kaye, a graduate student in political science, Kelly Caylor, an assistant professor in 22 eqn Winter 2006–07 ecohydrology at the University of Indiana; Jan Nordbotten, a visiting associate professor in civil and environmental engineering, and John Githaiga from the University of Nairobi. Both Githaiga and King will spend the spring semester at Princeton, conducting research and teaching. Rodriguez-Iturbe will lead a graduate seminar, to be co-taught by Githaiga and King, that will cover broad issues associated with water in Africa. “The seminar will cover politics and policy, hydrology, ecology—as many dimensions of the problem as possible,” said Celia. —TR The researchers conducted detailed analyses of plant species and soil types at several representative plots in central Kenya. This graph, prepared by graduate student Trenton Franz, shows, centimeter by centimeter, what soil types were present and what species, if any, grew in those soils. The data will help in creating computer models of the terrain, which can act as tool to help guide conservation efforts.

Fei-Fei Li, a member of the Princeton class of 1999, will join the computer science department as an assistant professor in January 2007. After earning her B.A. in physics with certificates in engineering physics and applied and computational mathematics at Princeton, Li obtained her Ph.D. in electrical engineering from California Institute of Technology in 2005. Since then, Li has served as an assistant professor at the University of Illinois UrbanaChampaign. In this capacity, she has explored her specialty field of computer vision with her students, using of state-of-the-art algorithms to address topics such as object recognition. In addition to her engineering work, Li has conducted research on health and medicine in Tibet in conjunction with two organizations, the One H.E.A.R.T. Foundation of Orem, Utah and the Tibetan Medicine Hospital of Lhasa, Tibet. Celeste Nelson, whose research interest are in bioengineering, will join the chemical engineering department as an assistant professor in January 2007. She comes to Princeton following a postdoctoral fellowship in the Cancer Biology Department of the Lawrence Berkeley National Laboratory in Berkeley, Calif. During her three years at the lab, Nelson focused on the regulation of mammary gland development. Since 2004, her research has been supported by the U.S. Department of Defense Breast Cancer Research Program. Prior to earning her Ph.D. in biomedical engineering from Johns Hopkins University in 2003, Nelson received two B.S. degrees from the Massachusetts Institute of Technology, in biology and chemical engineering. In addition to her numerous papers that have appeared in peer-reviewed journals, Nelson has since 2001 jointly submitted four provisional patent applications. The most recent, submitted in 2005 based on work done at the national lab, identifies a malignancy marker and mediator. Birgit Rudloff joined the Department of Operations Research and Financial Engineering as an assistant professor in September after finishing her Ph.D. in financial mathematics at Martin-Luther-University Halle-Wittenberg in Halle, Germany. While completing her dissertation, Rudloff spent nearly a year at the Instituto Nacional de Matematica Pura e Aplicada in Rio de Janeiro, Brazil. During that time, she was in 2005 awarded the Student Award at the Second Brazilian Conference on Statistical Modelling in Insurance and Finance. Rudloff worked as a postdoctoral project assistant in financial mathematics at the Vienna University of Technology and also worked with Bode Management Consultants of Hamburg, Germany, and DWS Investments, Germany’s largest fund management company located in Frankfurt. Rudloff began her career at Princeton this fall teaching “Special Topics in Statistics and Operations Research: Risk Measure Theory,” a graduate-level financial engineering course. eqn Winter 2006–07 27 ALUMNI NEWS Mentorship and freedom were defining experiences for new engineering deans Jamieson *77, Munson *79 and Poor *77 assumed top posts this year Photo courtesy of Purdue University by Steven Schultz Photo courtesy of University of Michigan Leah Jameson *77 Photo by John Jameson David Munson *79 H. Vincent Poor *77 28 eqn Winter 2006–07 They lived the graduate student life at Princeton, working long hours in offices just a few doors from each other, immersed in research but also absorbing a culture of mentorship and a broader sense of the world around them. Nearly 30 years later, Leah Jamieson and H. Vincent Poor, who graduated in 1977, and David Munson, who received his Ph.D. in 1979, have all risen to the top of their profession. Last summer, each became dean of a leading engineering school: Jamieson at Purdue University, Munson at the University of Michigan and Poor at Princeton. Jamieson, Munson and Poor all earned Ph.D.s from Princeton’s then-combined Department of Electrical Engineering and Computer Science. Poor and Munson were in the same research group, Information Sciences and Systems, with Poor advised by now­ emeritus professor John Thomas and Munson advised by Bede Liu, who is still a full-time faculty member. Jamieson’s advisor was Ken Steiglitz, now professor of computer science. While Munson compared the intensity of his graduate experience to being “shot from a gun,” all three said their time at Princeton helped them develop a working style that looks beyond the details of their research to see opportunities for teaching, inno vation and solving problems for the greater good. EQuad News recently arranged a conference call with the three newly minted deans; the following is an edited transcript of the conversation. A longer version is available at www.princeton.edu/engineering/news/3deans. How has graduate education changed since your time at Princeton? Dave Munson: For me, it’s hard to judge because Princeton was a different place from other places even back then. The Princeton experience was incredibly intense, and I felt like when I came out of the Princeton Ph.D. program I was shot from a gun. I don’t know that other programs at other schools, at least most other programs at other schools, were quite like that. Leah Jamieson: I would agree with that. One change I’ve noticed­—certainly one of the things that I see at a large scale in undergrad programs and now also in Ph.D. programs—is a more explicit component asking ‘How is this degree preparing you for a career in the real world?’ compared to an experience focused entirely on theory and research. At Purdue, we now are starting to talk with our Ph.D. students about professional practice instilled beyond research skills and that’s fairly new. Does that mean turning dials and nuts and bolts? What does that encompass? LJ: No, it’s not nuts and bolts. It’s emphasizing that whatever you end up doing you’re going to be practicing it in a context, maybe academia or maybe industry, but there are issues related to professionalism and ethics and communication that are going to be important no matter what you do. I don’t think that was ever explicit when I was a student. Vince Poor: Definitely the Ph.D. program at Princeton has gotten to be much more closely related to industry and application than it was when I was a student, at least in my own particular area of expertise. I remember that when I was a student there was very little discussion of industrial applications. It was a much more theoretical environment. The change is due partly to what Leah’s saying, that we realize students are going to be out there in the real world and they’re not all going to be academics. But it’s also partly just the winds of change in the field, that we’re all much more interested in the greater outside community and in how we impact that community than we were, I think, 30 years ago. What do you see as the biggest issues facing academic engineering programs? DM: At the undergrad level here at Michigan, we’re working hard on major interdisciplinary student projects and finding a way to formalize that as part of the curriculum. Leah has certainly done a lot in that area, but we have our own slant on it. We’re also working very hard on international programs, giving students a semester overseas, and working very hard on entrepreneurial programs and making it possible for students to start companies and for that to be integrated into part of the educational process. At the graduate level, we’re putting on big pushes in research on topics that have tremendous societal importance. We have a big new energy research center and a big new environmental sustainability research center. I’d say overall we’re trying to get more of our faculty involved in working on problems of global significance and not just on narrow specialties. LJ: I think Dave’s exactly right. For undergraduates, multidisciplinary learning is very important, and at Purdue service learning is a major component of that, as well as entrepreneurship and certainly international experiences. If I think about challenges for engineering, ALUMNI NEWS certainly globalization is important. We find that half of our students say that they would love to have an international experience before they graduate, but engineering is actually one of the lowest participants, in general, in international programs. So there’s a burning issue about becoming more global and preparing our students for global careers. Two of the other topics that we are focusing on are teaching innovation and teaching lifelong learning. The question about making people better lifelong learners—at both at the graduate and the undergraduate level—is an overarching theme in making sure that engineering addresses global problems and the context of the problems, whether it be energy or environment, healthcare engineering, sustainable systems, nanotechnology. Compared to five, ten years ago, when we used to talk about hiring faculty or educating students in specific disciplines—say, electrical or mechanical engineering—we’re now talking about focusing on these grand challenges. How do you hire faculty to work in the area of energy? How do you educate students to work in healthcare engineering? DM: One difference probably between Michigan and Princeton and Purdue is that Michigan has a major medical school. That changes the dynamic tremendously. We are heavily into bio, the medical side of engineering, and have about 100 joint research projects, for example. So that opens many possibilities for addressing these cross-disciplinary societal problems. VP: I would echo all of what Dave and Leah have said about this. The trends in engineering education are toward much greater emphasis on multi-disciplinary approaches to problems, a focus on the societal impact of what we do and on innovation, a greater adoption of experiential learning modes, and a recognition that our students will be working in a truly global community. At Princeton, I see the greatest challenge being to educate the next generation of leaders for a world in which technology is playing an ever more prominent role. This involves not only the education of engineering leaders, but also active participation in the education of all students at the University on issues of technology and its impact. What do you remember most fondly about your time as students at Princeton? DM: I remember a couple of things that are awfully positive. One was the exceptional quality of the student body. I was very, very impressed with my fellow students and learned a lot from them. The other thing is just the huge amount of time that I was able to spend with my adviser, Bede Liu, and the very fine mentoring I received. Bede had a group of reasonable size and worked very long hours and a lot of other faculty were in a similar mode, so they were always around. If you had a faculty adviser at Princeton, boy, you really had an adviser and you spent a lot of time with that person. That really helped set up my entire career. LJ: Yes, I agree with that—the advising, and I would say the camaraderie of the students, which at least in my case maybe came from running computer jobs in the middle of the night. That builds its own sort of community. The other aspect of the mentoring that I appreciated a little while I was there but more so as time went by was the sense that you were in an intellectual community at Princeton but also an intellectual community that extended far beyond Princeton. I remember Ken Steiglitz introducing me to people at conferences, for example, and thinking about who those people were, recognizing that he was part of this incredible intellectual community, that he was introducing me into that community. That feeling of inclusion was a very important part of the mentoring, and it took me a while to understand how important it was. VP: I agree, and another thing I would say is that I felt that I had an enormous amount of freedom as a student. Even though my adviser—like Dave’s and Leah’s—was always willing to spend time with me, I really had a lot of freedom just to explore. The research style in the department and the research topics that we were working on were such that I could really go in many different directions and allow myself to explore those directions. The freedom to do that was very important in establishing an intellectual work style that has been very good for me and my career. I don’t feel that I have to focus every moment on the most immediate problem at hand. I recognize that it’s productive sometimes to sit back and think about things that are a little bit out of the box, and I learned that in my days as a graduate student at Princeton. It was a great environment that really promoted creative thought.

Beginning with her work at Princeton on phase transitions in colloids, Gast became a leader in the study of complex fluids, an area of major importance to biotechnology, nanotechnology and materials science. She completed her Ph.D. in chemical engineering at Princeton as a Hertz Foundation Fellow, advised by William Russel, now the Arthur Marks ’19 Professor of Chemical Engineering and dean of the Graduate School, and Carol Hall, now at North Carolina State University. “As a graduate student, Alice became engrossed in the physics of polymers and colloids, completing work with Carol Hall and myself that easily ranks as my most frequently cited paper,” Russel said. “Alice naturally emerged as a leader in the profession through clear and strategic thinking, foresight, an organized style and charismatic expression of her ideas. The values she articulates for Lehigh with respect to integration of education with research, with synergy between undergraduate and graduate programs, coincide nicely with Princeton’s ideals. I think she has a wonderful future ahead.” Gast assumed the Lehigh presidency after nearly five years as vice president for research and associate provost at the Massachusetts Institute of Technology and 16 years as a chemical engineering professor at Stanford University. Her numerous honors and awards include election earlier this year to the board of the American Association for the Advancement of Science. She was previously elected to the National Academy of Engineering and named a Fellow of the American Academy of Arts and Sciences. From 1993 to 2000, she served as a member of the Leadership Council for Princeton’s School of Engineering and Applied Science.—HP eqn Winter 2006–07 29 ALUMNI NEWS Alumni participate in major review of Hanford nuclear facility by Steven Schultz John Rutgers ’56 (left) and John Bodman ’56 Photo courtesy of Silvia Ferrari John Rutgers ’56 (left) and John Bodman ’56 Silvia Ferrari *02 is the recipient of a 2006 Presidential Early Career Award for Scientists and Engineers. An assistant professor of mechanical engineering at Duke University, Ferrari received the PECASE award following her 2005 National Science Foundation Faculty Early Career Development Award. Together, these honors will provide her with more than $400,000 in research funding over the next five years. Ferrari earned her Ph.D. in mechanical and aerospace engineering from Princeton. At Duke, where she directs the Laboratory for Intelligent Systems and Controls, Ferrari’s research focuses on the advancement of adaptive control technology. 30 eqn Winter 2006–07 Two Princeton Engineering alumni helped lead a major review of the U.S. government project to clean up millions of gallons of nuclear waste at a former weapons plant in Hanford, Wash. John Rutgers, who graduated from Princeton in 1956 with a degree in civil engineering, chaired a 16-member review team described by the U.S. Department of Energy as the “best and brightest” in the field. Among those Rutgers recruited for the team was classmate John Bodman, a chemical engineer. Both described the review as a critical undertaking: restoring credibility to one of the nation’s largest environmental cleanup projects, which was in danger of losing congressional funding because of severe cost overruns. “It was a fascinating project, and we worked very well together as a group,” Bodman said. Rutgers said, “Through our work we were able to restore significant credibility to the project. I think we really contributed to solving a problem of national importance.” Briefs Office Depot has named Teddy Chung ’76 as its senior vice president and managing director, Asia, a new position in the company. Chung, who will be based in Shanghai, China, was previously the senior vice president, Asia Pacific, of Avery Dennison. After earning his bachelor’s in chemical engineering from Princeton and an M.B.A. from Harvard Business School, Chung worked with Booz Allen Hamilton before joining Avery Dennison in 1985. Teddy Chung ’76 ALUMNI NEWS w The Hanford Waste Treatment Plant, currently under construction, is intended to stabilize 50 million gallons of nuclear and chemical waste so it can be stored for more than 10,000 years. The waste, generated from weaponsmaking projects, is now in underground tanks that are beyond their designed lifespan. Some of the tanks are leaking into the groundwater, threatening to contaminate the Columbia River and the major population centers downstream, Rutgers and Bodman said. The two engineers said the price tag for the treatment facility had ballooned in the last eight years from less than $4 billion to more than $8 billion as first-of-a-kind technology design evolved and regulatory requirements changed. The review team, hired by Bechtel National Inc. at the request of the Department of Energy, worked long hours for three months before submitting a report at the end of March 2006 with major recommendations that were accepted by Congress. Photo courtesy of Webhannet River Design Three years after Leonard Liu *68 founded Augmentum, a software development firm based in Foster City, Calif., the company’s workforce has doubled in size from 500 employees to more than 1,000. The majority of the company’s programmers, who create software for industry giants including Microsoft, Dell and Intel, are based in China. Liu, who was recently featured in U.S. News & World Report and Newsweek magazines, earned his Ph.D. in electrical engineering at Princeton. He taught at the University of Michigan and then led research teams at IBM for over 20 years. Rutgers, a retired executive from Bechtel, has long experience managing projects in the nuclear and fossil fuel industries. Bodman, the president of John O. Bodman Consulting, has led the commissioning of numerous chemical and nuclear materials processing plants. Bodman said that completing the Hanford review required understanding not only highly technical information but also a complex regulatory and political environment. “I had been president of a large corporation but I really had to work to understand it,” he said. “The real puzzle is getting a handle on the entire environment in which you are doing your engineering and communicating recommendations effectively, and that is where the totality of our Princeton experience served us well, not just the engineering but the full education.” Symmetricom, manufacturer of atomic clocks, network synchronization tools and timing products, has appointed James Armstrong ’88 to be vice president of engineering at the company’s Telecom Solutions Division in San Jose, Calif. In addition to his bachelor’s in electrical engineering and computer science from Princeton, Armstrong holds a Ph.D. in electrical engineering from Purdue University. Prior to joining Symmetricom, he was president of Movidis, a privately held company that develops high-performance networking equipment. SteriCoat, a start-up company that has developed a coating technology for medical catheters, earned Chris Loose ’02 and Joel Moxley ’02 back-to-back honors from the Massachusetts Institute of Technology and Harvard University. Loose and Moxley, who are both graduate students in chemical engineering at MIT, collaborated with three other MIT researchers to develop the company’s method to significantly reduce catheter-related infections. Less than one month after their company won the $30,000 MIT Business Venture Robert P. Goldberg Grand Prize in May, it placed first in the annual Graduate School of Arts and Sciences Harvard Biotechnology Club Business Plan Competition. The team received $5,000 and a one-year lease for 1,000 square feet of lab or office space from Cummings Properties, valued at $25,000, for winning the Harvard competition.

Located in downtown Princeton, the park features playful garden sculptures that evoke the serious research that the scientists do. The park was created by landscape architects Alan Goodheart and Peter Soderman and architect Kevin Wilkes. Two years ago the threesome created another temporary park at the same location—on Paul Robeson Place— called “Writers Block,” a collection of garden follies inspired by the work of 11 writers. This time around, Soderman told the Princeton Weekly Bulletin, “science was the obvious choice because there are so many scientists in Princeton and most scientists are relative aliens to the lay public. People don’t understand what scientists do.” The five engineering faculty members with pieces in the garden are Perry Cook, professor of computer science; David Dobkin, dean of the faculty and professor of computer science; Naomi Leonard, professor of mechanical and aerospace engineering; George Scherer, professor of civil and environmental engineering; and Jim Sturm, professor of electrical engineering and the director of the Princeton Institute for the Science and Technology of Materials. For details about the project and each collaboration, visit the Quark Park Web site: http://www.princetonoccasion.org/quarkpark/. Professor James Sturm and President Shirley M. Tilghman, a molecular biologist, collaborated with artist Nancy Cohen to create an abstract representation of how mammals sense and remember scents. 32 eqn Winter 2006–07 All photos by Denise Applewhite Photo, top right: George Scherer collaborated with sculptor Kate Graves to create a stone table that incorporates a board for the African game of Mankala.

One is protected by a liquid preservative invented in Scherer’s lab. The other, left bare, was expected to crumble from the force of salt crystallization. Naomi Ehrich Leonard collaborated with glass artist Bob Kuster to represent Leonard’s work with robotic gliders that self-choreograph their movements in response to their environment. Perry Cook collaborated with sculptor Jonathan Shor to create a giant granite xylophone whose sounds are modified as they are made by digital signal processing equipment. David Dobkin collaborated with architect Kevin Wilkes to design the outdoor theater and roof covering at Quark Park, which was inspired by Dobkin’s work on rendering complex shapes in computer graphics. eqn Winter 2006–07 PrincetonUniversity School of Engineering and Applied Science Undergraduate Admission Office Graduate Admission Office www.princeton.edu/engineering T(609) 258-3060 F(609) 258-6743 T(609) 258-3034 F(609) 258-6180 www.princeton.edu/engineering/undergraduate www.princeton.edu/engineering/graduate Princeton, NJ 08544-5263 USA eqn Winter 2006–07 Box 430 Princeton, NJ 08544-0430 011 Clio Hall Princeton, NJ 08544
