Bio

Research

I am a geologist and geochemist with broad interests that span Earth History, Earth System Science, and Astrobiology. I use a variety of rock archives, including chemical sediments, glacial tills, and igneous rocks as records of the interactions between life, the oceans, the atmosphere, and the solid Earth over deep time. I access these archives through field work, analytical and isotope geochemistry, and numerical modeling to investigate deep time questions about Earth history.
