Earth and Environmental Sciences Faculty

Xingchen (Tony) Wang

Assistant Professor

Profile

The Wang Stable Isotope Biogeochemistry Lab focuses on using stable isotopes to understand the biogeochemical cycles (with a focus on N, but also including C, O, and S) in the modern and past oceans, their interactions with climate, and their implications for Earth’s habitability and the evolution of life. 

Current Lab Members:

Yuwei (Cindy) Wang, Research Associate

Danielle LeBlanc, third-year graduate student (co-advised with Prof. Jeremy Shakun)

Fengyao Li, first-year graduate student

Kameko Landry, first-year graduate student

Alexis Burns, Class of 2021

Carlos Tramonte, Class of 2021 (co-advised with Prof. Sarah Davies at BU)
