Curriculum Vitae:

Ram Vasudev

I came to JPL after spending many years in academia, including a postdoctoral research associate position with Prof Richard Zare at Stanford and subsequently as a faculty member at universities where I conducted research with funding from the National Science Foundation and other agencies. I joined JPL in 2001 as a research scientist in Chris Webster's Atmospheric Laser Spectroscopy Group and, when Chris became a program manager, I transitioned to the Planetary Chemistry and Astrobiology Group in ~2007. My work has been funded through JPL's R&TD program and through NASA's PIDDP, ASTID and LASER programs.
