I received my PhD in Geosciences and Astrobiology from Penn State University. I am interested in the evolution of planetary atmospheres, both for Earth throughout its history and for other potentially habitable worlds. My research utilizes photochemical and climate models to study how interactions between solar radiation, surface processes, and life can influence climate and atmospheric chemistry.

My previous research focused on the climate of early Earth—in particular, constraining atmospheric carbon dioxide during the Archean Eon, and exploring changes in oxygen over time—and early Mars.
