Bio
As a Ph.D. student, I work with Dr. Ben Johnson to model the evolution of Earth’s biogeochemical nitrogen cycle over deep time. In particular, I focus on reconstructing global emissions of nitrous oxide (a greenhouse gas which depletes the ozone layer) to resolve its effects on “hothouse” climate and atmospheric chemistry over the past 550 million years. I also study changes in atmospheric pressure due to biological nitrogen sequestration into the solid Earth over geologic timescales, with potential impacts on past climate stability. More broadly, I am interested in using computational tools in biogeochemistry and geobiology to investigate topics in Earth history and planetary science.
