Research Interests:

My research interests revolve around understanding how terrestrial ecosystem structure and function are affected by human-accelerated environmental change, such as climate change, elevated atmospheric deposition, alterations of species composition, or land-use conversion. More specifically, I am interested in the interactions between carbon and nitrogen biogeochemical cycles and how these interactions are altered under changing environmental conditions. Furthermore, what are the implications of these biogeochemical changes on down-stream aquatic systems?
