TODD B. SAUKE
(408) 924-5437 (ofc.)

As Principal Investigator on a series of NASA research tasks, Todd Sauke is 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.

Professional Experience

Principal Investigator October, 1993-present. NASA Exobiology, PIDDP and Astrobiology research tasks investigating space-flight and planetary exploration applications of isotopic measurements using NASA's second generation Stable Isotope Laser Spectrometer (SILS II) instrument.
Research Scientist April, 1991-present. SETI Institute employee working at NASA Ames Research 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 Electrostatics of Granular Materials microgravity project which was being developed for deployment on the International Space Station. An interesting aspect of the project involved testing of EGM hardware on NASA's KC-135 zero gravity aircraft.

Instructor September, 2002-present. Physics Dept., San Jose State University. Teaching various laboratory sections for courses 120-I, Laboratory Electronics for Scientists, and other introductory physics courses. Also teaching various introductory physics courses including Mechanics, Electricity and Magnetism, and Modern Physics.

Research Scientist 1989-1991. National Research Council Associate at NASA Ames Research Center. Diode laser spectroscopy of stable isotopes of carbon.

Research Assistant 1982-1989. Physics Dept., University of Illinois, Advisor: Dr. Hans Frauenfelder. Spectroscopy and flash photolysis of heme proteins and their binding of small ligands, e.g. CO and O2. A major aspect of the work involved the development of mathematical and physical models to account for experimental data. Designed, built, tested, and used a microprocessor controlled, logarithmic/linear timebase, realtime, 1 MHz, data collection/ processing instrument.

Teaching Assistant 1980-1982. Physics Dept., University of Illinois. Conducted discussion sections and lab sessions for general physics courses at the freshman and sophomore levels.

Researcher Summers, 1977-1979. In Undergraduate Research Opportunities Program (UROP), Massachusetts Institute of Technology. Cataract research was performed seeking a unified understanding of the origin and possible reversibility of a wide range of cataract types, e.g. diabetic cataract, galactosemic cataract, senile cataract, and cold induced, reversible cataract observed in the lenses of young mammals.
