Areas of Expertise: My research focuses on the effect of human impact and natural disturbances on aquatic and terrestrial ecosystem function. I am examining how changing forest structure (due to climate change, pest invasions, acid deposition, and restoration) alters stream nutrient dynamics and metabolism. I also am working to understand how natural disturbances (i.e., Hurricane Sandy), and novel contaminants (pharmaceuticals and personal care products) both alter aquatic and terrestrial ecosystem function. My work addresses these issues in watersheds and streams located in natural areas (Hubbard Brook and HJ Andrews Experimental Forests, Susquehanna) and urban centers (Baltimore Ecosystem Study).
