TODD B. SAUKE
(408) 924-5437 (ofc.)
As Principal Investigator on a series of NASA research tasks, Todd Sauke has been applying his
experience in tunable diode laser technology to the development of planetary exploration
applications for the measurement of isotopic ratios in planetary surface and atmospheric samples. In
particular, it is hoped that space-flight missions to the surface of Mars can use the diode laser
technology being developed to help look for evidence of past (or even existing) microbial life forms
in Martian surface samples. On earth, this isotope measurement technology finds productive
application to a wide variety of medical diagnostic tests. A co-inventor on two patents in this field,
Todd Sauke is pursuing the cooperative research and development programs that will result in the
advancement of technology needed for both applications.

Center. Diode laser spectroscopy of stable isotopes of carbon. Included leading work on
designing and implementing the hardware and software for NASA's second generation Stable
Isotope Laser Spectrometer (SILS II) instrument for highly accurate (~0.1 %) isotopic
measurements of stable isotopes of carbon in CO2. One application being pursued is that of
developing an instrument capable of measuring isotopically-labeled human breath for the
medical diagnosis of disease. Also participated as Co-Investigator (1999-2001) on the
