Xuyuan (Ellen) Ai

Ai is based in the Department of Geosciences, where she studies the changes in biogeochemical conditions in the Southern Ocean through glacial-interglacial climate cycles during the past 450,000 years, with a focus on surface-nutrient consumption by phytoplankton. She is advised by Daniel Sigman, the Dusenbury Professor of Geological and Geophysical Sciences and professor of geosciences.
