Hello! I am a fifth-year graduate student working with Prof. Nikole Lewis and Prof. Jonathan Lunine on planetary spectroscopic retrievals. Briefly, this involves analyzing spectroscopic data from solar system bodies and exoplanets using appropriate physical models and statistical tools. The goal is to infer properties like composition, temperature, etc. of the atmosphere or surface of the body being observed. These methods can also be applied to simulated data from future missions/observatories, to help assess their science output and inform their design.  As a long term goal, I would like to explore how these retrieval frameworks can aid the astrobiological exploration of potentially habitable exoplanets and icy moons in the outer solar system.
