Find out what this lab does

Our research programs are designed to advance predictive understanding of ecosystem ecology and biogeochemistry under the global environmental change via data-model integration. Major issues we are addressing include (1) how global change alters structure and functions of terrestrial ecosystems, and (2) how terrestrial ecosystems regulate climate change. Our research is aimed at quantifying dynamics of carbon, nutrient, and water resources in ecosystems in responses to environmental changes.
