Xingchen Tony Wang



Xingchen (Tony) received a B.S. in Geochemistry from Nanjing University (China) in 2010. Following, he came to Princeton University to pursue a Ph.D. in Geosciences. His thesis work is focused on improving the understanding of nitrogen and carbon cycle in the modern and past ocean, by developing and applying a novel geochemical proxy--nitrogen isotopes in stony corals. He is a Charlotte Elizabeth Procter Fellow of the Graduate School at Princeton University, a Schlanger Fellow of Consortium for Ocean Leadership, and a student member of Princeton Energy and Climate Scholars
