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 focuses on using stable isotopes to document and understand the cycling of biologically important elements (with a focus on N but also including C, S, O and P) in the modern and past oceans, their interactions with climate, and their implications for Earth’s habitability and the evolution of life. 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.
