Yuzhen Yan
Yuzhen is interested in the Earth’s climate history 1 million years ago. He uses ice core records from Antarctica to reconstruct polar temperature, greenhouse gas concentration, and atmospheric composition in collaboration with researchers across the country. His research will shed light on how greenhouse gas concentrations and the Earth’s climate state co-varied before human’s impact on carbon cycle . Here at Princeton, Yuzhen measures the elemental and isotopic composition of major gases (nitrogen, oxygen, and argon) to provide key constraint on the timescale of ice cores.
