The focus of my research is on ecosystem ecology and biogeochemical cycling in freshwaters. Freshwater is one of society's most important resources; however, our sources of freshwater are threatened by a variety of anthropogenic activities from urbanization, eutrophication, and damming, which can all be confounded by climate change. In light of global change, therefore, it is key to understand how these stressors potentially alter ecosystem processes in order to predict and mitigate these threats to our freshwater ecosystems. My main research focus is to understand how streams and rivers transform, store and export carbon and nutrients. I am interested in the interaction of abiotic forcing, such as changes in hydrology, and biotic drivers (from microorganisms to people) on biogeochemical cycling in fluvial freshwaters.

Research interests: ecosystem ecology, biogeochemistry, stream and river ecology, stream metabolism, carbon and nutrient cycling, anthropogenic stressors on freshwater ecosystems
