The overall goal of my research program is to inform responsible stewardship of natural resources. I am intrigued by the causes of broad, general patterns in food web dynamics and ecosystem processes, and in ways to assure ecological and societal sustainability in the face of increasing human influences on ecosystems.

I study mechanisms that link primary production, decomposition, and food web dynamics because I believe this gives the most complete understanding of the functional integrity of ecosystems.

Although I have worked in many systems, I often focus on wetlands at the aquatic-terrestrial interface because in spite of their relatively small global coverage, these habitats support a disproportionately high number of essential ecosystem services.

My current research is focused on three themes:
