My primary research interests are to understand and quantify human and natural controls over ecosystem patterns and processes by using a systems approach, ecosystem modeling, and data-model assimilation at various spatial and temporal scales. My current study mainly focuses on
Assessment of the dynamics of ecosystem function and services in response to multiple global changes in climate, land use and cover patterns, land management practices, and atmospheric composition (e.g., CO2, O3, nitrogen deposition);
Land-atmosphere exchange of greenhouse gases (CO2, CH4 and N2O);
Coupled carbon, nitrogen and water cycles in the earth system;
Nitrogen regulation to ecosystem productivity, crop yield, carbon sequestration capability, and water quantity and quality;
Land-coastal linkage and riverine export of carbon and nutrient.
