Sincerely, John Lorch Chairperson jlorch@bsu.edu Inside this issue: New Faculty p 2 & 3 Where Are They Now? P 4 & 7 Faculty & Student Publications p 5 Retirement News p 5 Faculty News p 6 New Faculty Roza Aceska completed her master’s degree in mathematics from State University in Macedonia where she held a docent position in 2010-2012. She earned her PhD at the University of Vienna in 2009. Roza is interested in topics at the intersection of time-frequency analysis and sampling theory. She has expertise on the analysis and reconstruction of sound-like functions and collaborated with the Numerical Harmonic Analysis Group and the Acoustics Research Institute in Vienna. She likes that her formulas have practical importance and deliver better sound quality not only for hearing aids, but also for mobile phones and MP3 players. Roza previously held a temporary position at Vanderbilt University. Her team introduced a sampling technique that provides perfect reconstruction when using significantly less than a minimal number of sensors. She finds teaching mathematics to be joyful and rewarding. She is excited to work with students who are energetic and gifted for mathematics. Having lived in two music cities, Vienna and Nashville, Roza developed an ear for music and enjoys the concerts of the Muncie Symphony Orchestra and the School of Music. Most recently he taught in a school for missionary children in Papua New Guinea where he taught all levels of mathematics from grade 2 through calculus. He also provided administrative support for the elementary school in Papua New Guinea. Patrick has published a number of articles in mathematics education journals. He has also presented at regional, national, and international conferences. He served as the president of the Indiana Council of Teachers of Mathematics from 2002-2004. Patrick enjoys teaching at all levels and especially enjoys innovative instructional strategies. Articles like “Triangles ala Fettuccini” (Mathematics Teacher, 2001) and “Experiencing Radians” (Mathematics Teacher, 1999) shared some of his creative instructional methods publicly He has also shared several presentations on how to incorporate calculator technology effectively into instruction. Dusty Grundmeier joined the department of mathematical sciences after completing a 3-year postdoctoral fellowship at the University of Michigan. He earned his PhD in mathematics from the University of Illinois at Urbana-Champaign in 2011. Dusty also previously spent six months as a guest researcher at Norwegian University of Science and Technology in Trondheim, Norway. He recently gave a public lecture series "From the African Stones Game to Cauchy-Riemann Geometry" in Uganda. Dusty's research lies in the intersection of complex analysis, commutative algebra, and combinatorics. His current research focuses on introducing algebraic techniques to mapping problems in several complex variables and connecting this work with questions in number theory. Originally from Minnesota, Dusty has a healthy respect for winter, hockey, and mosquitos. Patrick Eggleton earned his bachelor’s degree in mathematics education from the University of South Florida. He taught high school for four years while completing his MEd at University of South Florida. At the University of Georgia he joined the RADIATE research group, an NSF funded research group that explored questions regarding pre-service teacher preparation. He completed his PhD in mathematics education from the University of Georgia in 1995. Patrick has taught at Berry College (Georgia) and Huntington University (Indiana). 2 New Faculty Jeff Hiatt joined the department as full-time contract faculty teaching Math 111 and Math 125. He received his BS in mechanical engineering from Purdue University and an MBA from Indiana Wesleyan University. Jeff spent 35 years working in industry in various positions in design, manufacturing, and quality engineering. He took an early retirement from Chrysler Corporation in 2008. He taught math as adjunct faculty at Ivy Tech and also was a substitute teacher for Muncie Community Schools after retirement. He most recently worked for Keihin Aircon in Muncie. Jeff was born in Muncie and graduated from Northside High School. His wife, Regina, is a Ball State graduate, earning bachelor’s and master’s degrees in elementary education. She teaches 6th grade English at Northside Middle School. Jeff’s dad and sister also graduated from Ball State with bachelor’s and master’s degrees in secondary mathematics education and both are retired from Muncie Community Schools. Jeff has two sons. Sam graduated from Butler University with a doctorate in pharmacy, is married, and lives in Winston-Salem, North Carolina. Eli lives and works in Muncie and is attending Ivy Tech part-time pursuing a degree in criminal justice. Dan’s research area is topology and geometry. More specifically, “I am interested in topics at the intersection of knot theory and symplectic topology such as Legendrian knots. These are embeddings of the circle into 3-dimensional space that satisfy a certain differential equation. A Legendrian knot can be visualized as a knotted string with the loose ends connected to one another, and the differential equation results in the appearance of cusp points when the knot is viewed from a particular angle. (Try Google for an example).” In addition to math, Dan’s interests include listening to and playing music, especially jazz; and hanging out with his wife, Erin, and their two Chihuahuas. Members of the Ball State Council of Teachers of Mathematics attended the Nional Council of Teachers of Mathematics regional conference in Indianapolis on October 30 and 31. BSCTM is the only student affiliate of NCTM in the state of Indiana. These pre-service teachers were able to attend several professional development sessions, and they shared what they learned at BSCTM’s November meeting. Pictured are: Steven West, Katherine Thomas, Khloe Vonderheide, Nicole Yingst, MacKenzie Cox, Krista Hemmelgarn, and faculty advisor LeAnn Neel-Romine. Dan Rutherford earned his bachelor’s degree in mathematics from Western Washington University and then went on to earn his PhD at the University of California, Davis in 2008. Before coming to Ball State, he held temporary positions at Duke University and the University of Arkansas. He also spent a month visiting Max Planck Institute for Mathematics in Bonn, Germany. Dan states ‘”I truly enjoy teaching math, and I am excited to work with the many enthusiastic and talented students here at BSU.” 3 Where Are They Now? By Charles McConnell The story begins early in my life but on my journey I graduated from Indiana Tech in 1961 with a BS in mathematics and a minor in engineering. I was in the Air Force Reserve in 1962. From September 1962 to June 1964, I was a graduate student and teaching assistant at Ball State. The mathematics professors from whom I took courses were Earl McKinney, John Hoelzer and Duane Deal. The other mathematics professors with whom I was in contact, either grading papers or tutoring their students, were Ramon Avila, John Beekman, Charles Parish and George Grunwald. They were all great teachers and my experience at Ball State was very positive. I received a master’s degree in mathematics and a minor in physics. From September 1964 until June 1968 I was mathematics faculty at the University of Wisconsin at La Crosse. From September 1968 until 1971 I was a graduate student and teaching associate at the University of Minnesota concentrating on differential equations and numerical analysis. In 1975 I completed my PhD in mathematics at Sussex College in England. My work was in the general area of numerical solution of parabolic partial differential equations. In 1975 I started teaching full time at Midwest College of Engineering, Lombard, Illinois (now part of Illinois Institute of Technology). I taught undergraduate and graduate engineering mathematics plus some undergraduate engineering courses. In the summer of 1976 I did post graduate work in the area of response surface methodology at the University of Missouri, Columbia. I continued teaching full and part time at Midwest College of Engineering until 1986. The summers of 1977 and 1978 I held summer faculty fellowships at NASA, Lewis Research Center in Cleveland, Ohio. It was a great experience working with these mathematicians. From 1979 to 1999 I worked in industry. The work was in applied mathematics and statistics. In particular, basic statistic, design of experiments, statistical quality control and stochastic processes (Reliability & Markov Chains) for the Singer Corporation and Thompson Steel Corp. I also worked for consulting companies of W. A. Golomski & Associates and Frank Mack & Associates. Some of the companies we did work for were fortune 500 companies. The American Society of Quality Control put one of my reliability models on the internet. From January 2000 until June 2014 I taught mathematics at the Illinois Institute of Art, Chicago. An interesting course I taught the art students was Concepts in Modern Mathematics. This course included elements of chaos theory, fractal geometry, sets, logic, functions (exponential & logs) and an introduction to catastrophe theory. It was great fun to see how some of these art students applied these modern topics to their projects. During the 50 years from 1964 to 2014, I published eight papers and gave five talks at professional meetings. “Computing a Best Discrete L1 Approximation Using the Method of Vanishing Jacobians” was delivered at the first international conference on data analysis based on the L1 norm and related methods, August 31 to September 4 1987, at University of Neuchatel, Switzerland. Also, in the 1980’s I was asked to become a referee for several papers to be published in the Journal of Computational Physics at Lawrence Livermore Laboratory. For the past 20 plus years I have been working on “Auction Market Problem.” This work produced a mathematical computer trading model that captures small moves in the market using, among other things, chaos theory and fractal geometry. It has been tested on the Futures Markets of Soybeans, Corn, Live Cattle, US 30yr Bond, 10 year T-Note, and the Emini S&P 500 with very good results – a new career? I am sure it will work on the US dollar vs. the Euro and stocks. As my students from Ball State to the present have told me, “you really like mathematics!” I really do like mathematics because mathematical problems present great mysteries! I would enjoy hearing from any student that I had at Ball State or any faculty at Ball State from 1962 – 1964 (mcconnell9542@yahoo.com). 4 Faculty and Student Publications Retirement By Patricia Parkison My career at BSU seems to have come full circle. I began my career in the fall of 1983 teaching algebra in the evening. My daughter was due at the semester’s end. Now as my career comes to an end, I am teaching algebra in the evening. My granddaughter is due at semester’s end! I have enjoyed a wide variety of teaching opportunities over the past 26 years as a full time contract faculty member. I taught basic math classes 107, 108, 111, and 131. I also taught math education courses 201, 202, 203, 207, 391 and 392 and summer courses to elementary education school teachers. I have enjoyed the variety and the challenges each course presented. I have seen many courses come and go and some even evolve. Being part of this process has been interesting, rewarding and, at times, quite a learning curve. I have had many opportunities to serve both at department and university levels. At both I have been able to develop and initiate changes that captured my passion to serve as an equal. I have experienced both failures and great successes and learned from each one. I have met many great people and made many friends while pursuing my interests. It has been an honor to serve. I have been exposed to many amazing students. I will remember those rare times looking in the right direction at the right time to see the light bulb go off and a new understanding of the material begin. I will remember those students whose very presence seemed to signify a greatness yet to be. They surely are destined to become the new leaders in their fields. I am thankful for those students who challenged me and made me a better teacher and a better person. These students are the country’s future and I will retire with confidence that all will be well. I will enjoy my wonderful family as it changes and grows; engage in 100 different projects, hopefully finishing a few; and continue to serve my community.

He also gave an invited presentation, entitled 6 Where are They Now? By Dr. Dr. h.c. mult. Alan Huckleberry My first contact with Ball State mathematics came in 1957 through my high school geometry course which was part of an experimental program in which BSU was involved. We built up a theory from scratch (Axioms, etc.) and every day for a year we proved theorems. I loved it. Probably as a result of this course, I was awarded a scholarship to spend the summer after my junior year in an NSF program at Kansas University. I remember reporting on this to Professor Higgins' math education class during the following fall semester. In the fall of 1959 I entered Yale as a math major. During the summers I worked as an apprentice actuary at Occidental Life in LA. Despite my true interest being in mathematics, my studies gradually drifted toward statistics, even biostatistics. In 1963 I graduated from Yale and returned to Muncie having no idea what to do. I decided to enter the mathematics MA program at Ball State and in 1963 I met John Beekman who put me onto a small research project on the pure math side of statistics. This was exciting for me and the courses were also very interesting. I particularly remember the lectures of John Hoelzer, Earl McKinney, and Duane Deal. Primarily due to the project with Beekman, in early 1964 I began looking for mathematics faculties where I might continue toward a doctorate in an area in or around probability theory. For various reasons, including the possibility of studying with Kai Lai Chung, I chose Stanford, where I began my PhD studies in 1964. Probability was still in its foundational stage (Kolmogorov's book had appeared only roughly 30 years before) and I found no real connection to it. Fortunately, in the completely informal setting of a pool hall, Halsey Royden asked me if I had any particular interests. I told him complex analysis (based on the beautiful lectures of Max Schiffer) but I was missing the geometry. He laughed and told me that complex analysis is geometry and a few months later he became my thesis advisor. Toward the end of my PhD studies luck struck again when two distinguished mathematicians, Aldo Andreotti from Pisa and Wilhelm Stoll from Notre Dame, visited Stanford for a year. I was the only real student in Andreotti's fantastic course. He asked me to write up the notes and to come to his house on the weekends to go through them. In the second semester he asked me to take over the course, lecturing to him and Stoll on certain analytic topics 7 which were becoming important at the time. In 1969, with my wife Barbara (a student of my father at BSU) and our 5 month old baby (now a professor of piano at University of Iowa), I moved to Pisa to take a post doctorate with Andreotti. This was the beginning of my "globalization.” At the end of that year I made the decision to take a tenure track position at Notre Dame. I was strongly influenced there by a number of geometers who were permanent faculty members and guests. Among them were Karl Stein and Reinhold Remmert who were leading figures in the German school of complex geometry. As a result of these contacts, I spent many extended visits in Europe, primarily in the Muenster group of Remmert. After being promoted to full professor at Notre Dame in 1978, I began a one year visit to Muenster supported by the Humboldt foundation. I was fortunate to be embedded in a European mathematical culture with contacts to various centers in Germany, Italy and France. In 1980 I made the difficult decision to take the chair of complex analysis at Ruhr Universitaet Bochum. I was extremely fortunate to step into the school of German complex geometry which had been built up after WW II by Stein, Grauert, Remmert and Hirzebruch. I was able to continue this tradition in Bochum in addition to carrying out my own research in the areas of complex geometry, Lie group actions and certain topics in mathematical physics. Many doctoral students received their degrees under my guidance (see my websites for further information on my research and students). Including those at Notre Dame and Jacobs University in Bremen, where I am now "Wisdom Professor of Mathematics", the number is now approaching 40. I am proud to say that a large percentage of them are active in academia. I have expanded my international work to centers in Eastern Europe, in particular Warsaw and Moscow, and to the Far East and Australia. I am involved in research projects funded by Deutsche Forschungsgemeinschaft in Bochum and Bremen in which I am guiding theses in various directions. This semester I am giving a course "Foundations of Mathematical Physics" in Bremen and am lecturing in a seminar in Cologne on "Integrable Systems."
