I am an earth systems scientist with backgrounds in geology, geochemistry and microbiology. My main research interests involves characterizing the biogeochemical cycles of some select elements (Cr and Fe), which yields information on how Earth’s surface conditions have evolved over geologic time. I do this by linking modern geochemical observations of rocks, sediments and seawater with conceptual computer models to develop detailed frameworks for the behavior of these elements over a wide range of environmental conditions. I then apply these frameworks to key intervals throughout Earth’s history in order to gain insight into the evolution of Earth’s biosphere, the history of oxygen in the ocean atmosphere system, mass extinction events, and climate change.
