RESEARCH

I study volatile loss from Mars via measurements and models, focusing on H escape from the extended corona surrounding the planet. By analyzing data from ESA’s Mars Express spacecraft, I discovered the time-variation of hydrogen escape from Mars, an observation which significantly changes the story of how Mars dried out over solar system history. I provided explanations for these variations with photochemical modeling that introduces new channels for H escape that oxidize Mars over time. I continue to study the H corona with MAVEN and am affiliated the Emirates Mars Mission UV spectrograph, which will arrive at Mars in 2021.
