Bio:
I am an Earth System scientist, geologist and geochemist. My work seeks to understand the evolution of the Earth over deep time and how it can serve as context for newly discovered exoplanets. Utilizing geochemical, geologic, and modeling techniques I have investigated the history of the Earth system nitrogen cycle, microbial activity during Snowball Earth, and volatile cycling on our planet.
