I am currently a Simons Foundation postdoctoral fellow (SCOL) at California Institute of Technology. I received a B.S. in Geochemistry from Nanjing University in 2010 and a Ph.D. in Geosciences from Princeton University in 2016. My research is focused on the cycling of nitrogen in the modern and past oceans. As a part of this effort, I develop and apply new methods to analyze the isotopic composition of nitrogen in fossils (e.g. corals and stromatolites) as well as in modern marine environments (e. g. reefs). I also employ calculations from simple mathematical models to quantitatively interpret these data. I am interested in ocean biogeochemical changes over a broad range of timescales throughout the Earth history, ranging from the Archean to the Anthropocene.
