Carbon Cycle And Ecosystems

Biography

Terrestrial ecosystems interact with our planet’s climate through exchanges of carbon and water. My primary research interests are to quantify these exchanges and understand their sensitivity to changes in forcing, using observations and models of carbon, water, and their interactions across the Earth system to track CO2 movement through the land and ocean. My research spans natural and urban ecosystems.
