Dr. Sander is a Senior Research Scientist at JPL with more than 40 years of experience in lab kinetics, photochemistry and spectroscopy, instrument development and flight missions with applications to Earth and planetary atmospheres. Current laboratory studies include kinetics of tropospheric reactions of organic peroxy radicals and Criegee biradicals, upper atmospheric radical kinetics of HOx, NOx and halogen oxide species, gas-surface reactions relevant to methane on Mars, and hydrocarbon reactions important in Titan’s atmosphere. Dr. Sander is Co-Chair of NASA’s Panel for Data Evaluation which publishes periodic critical evaluations of laboratory data for atmospheric modeling. Another research focus is remote sensing spectroscopy for atmospheric trace gases and aerosols. He has developed and deployed several atmospheric Fourier transform and dispersive spectrometers at JPL’s Table Mountain and CLARS facilities. He is PI and Co-I of NASA technology tasks to develop prototype geostationary imaging Fourier transform spectrometers. He has served on the science teams of several NASA atmospheric composition instruments including UVSI, TES, OCO, OMI and SAGE III. Dr. Sander has over 170 peer-reviewed publications in chemical kinetics, photochemistry, spectroscopy, instrument design and remote sensing. He also serves as the Chief Engineer and Acting Chief Technologist of JPL’s Science Division.
