DESCRIPTION:Volatiles\, such as water\, CO2\, and certain organic compounds
 \, are not just life's building blocks but also regulate the climates and h
 abitability on planetary bodies. By constraining results from current space
 craft exploration through data analysis and experiments\, developing new sp
 ace instrumentation\, and exploring theoretical concepts\, I seek to determ
 ine the key geological processes that affect the retention\, loss\, and che
 mical evolution of volatiles on planetary bodies. \n\n \n\nIn this seminar\
 , I focus on our Red Neighbor as the focal point for comparison with Earth’
 s evolution. The contrast between the currently frozen Mars and the geologi
 cal evidence for liquid water in its deep past raises significant questions
  about atmospheric and hydrospheric depletion over geological timescales on
  the red planet. The Perseverance rover is currently exploring ancient habi
 table environments in Jezero Crater\, Mars and has detected carbonate and h
 ydrated minerals as well as potential organics. I will examine these detect
 ions\, compare them to the observations from previous orbital and landed mi
 ssions\, and use them to identify geological processes that sequestered CO2
  and water on Mars – perhaps causing a different trajectory in planetary ha
 bitability when compared with ancient Earth.\n\n \n\nIn addition\, I will p
 rovide you an exclusive preview of current projects here at Stanford\, expa
 nding my research to understand volatile cycles of Venus\, detection physic
 s within ice\, salts\, and organic compound mixtures on airless bodies\, an
 d developments within metamaterial-based ultraspectral commercial sensors.
