Research Interests/Duties
My current research interests include: forest responses to global change; restoration of ecosystem processes in degraded forest; and, production ecology and biogeochemistry. This research is important because nutrient cycles determine site fertility and site fertility drives ecosystem productivity. Further, nutrient and carbon cycles are tightly coupled, and carbon cycling has effects on both nutrient cycles and atmospheric carbon dioxide, which in turn impact global climate. Global climate can then feed back on carbon and nutrient cycles.
