My limnological research focuses on the interaction of biogeochemistry and food web processes in lakes. I am especially interested in prediction of lake characteristics from land-water interactions and food web processes, including human effects such as fishing and introduction of exotic species. My research on these topics is connected to the LTER, Trophic Cascade, Water, Sustainability and Climate, and Bioeconomics of Aquatic Invasive Species projects.

I also work on resilience of linked social-ecological systems through collaborations with the Beijer Institute of Ecological Economics and Resilience Alliance. My work in complex systems and early warnings is connected with the Synergy Program for Analyzing Resilience and Critical Transitions (SparcS).

I am helping in the launch of the South American Institute for Resilience and Sustainability (SARAS).

 Teaching Program

My primary teaching assignments are courses on creation and analysis of ecosystem models (Zoology 535) and on approaches for fundamental research on ecosystems (Zoology 725). In addition I occasionally teach graduate seminars on ecosystem services, scenario thinking, and other aspects of sustainability science.
