About Me

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 understand the biogeochemical cycles 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 modern marine environments as well as in fossils (e.g., corals and stromatolites). 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’s history, ranging from the Archean to the Anthropocene.
