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.
