Curriculum Vitae:

Rohit Bhartia

For the last 16 years, Rohit Bhartia has been leading research and instrument development programs for deep UV based native fluorescence/Raman instruments for JPL under NASA (Astrobiology, organics, and life detection), NSF (life detection in extreme environments), and DoD (chemical/biological/explosives) programs. Under this program he has led a multi-institution team in developing the science and the instrumentation for to enable organic and life detection analysis for planetary science and terrestrial applications. This has led to the first hyperspectral deep UV native fluorescence/Raman imaging for differentiating and characterizing organics and/or microbes on natural surfaces and is the Deputy-PI on the selected Mars 2020 flight instrument (SHERLOC). He has also led instrument deployments to extreme environments such as Antarctica, the Arctic, Death Valley, and the deep ocean subsurface. His work has also led to data analysis methods that focus on using the technology for life detection by fusion of deep UV native fluorescence and deep UV Raman spectroscopy. His current efforts focus on spatially correlated organic chemistry with mineralogy analysis using a combination of native fluorescence and Raman spectroscopy to understand the distribution of organics/microbes to deduce their provenance or mechanism of survival. This research focus extends from planetary science with life detection and the origin of organics to detection and characterization of extreme life on earth and development of tools for water quality analysis or biological/chemical threat detection.
