UKSA Aurora Fellow

I am working on data analysis for the ExoMars Trace Gas Orbiter Atmospheric Chemistry Suite. MY objective is to measure high quality vertical profiles of gases present in the atmosphere of Mars, to search for undetected species, such methane and other organics, and chlorine- or sulphur-bearing molecules. I use these results to help understand the photochemistry, dynamics, and climatology of Mars.

I recently moved to Oxford from Paris (LATMOS/LMD/CNRS). Prior to that, I earned my PhD at the University of Toronto.
