I am a postdoc in the Department of Earth System Science at the University of California, Irvine. My research focuses on global marine biogeochemical cycles and involves mathematics, physics, biology, chemistry, and computer science.

Lately I have been developing AIBECS, a Julia package to allow oceanographers to simulate marine tracers with ease — check it out!
