Research Projects

Freshwater is often considered the most important natural resource, but freshwater resources are threatened by anthropogenic activities including habitat degradation, urbanization, eutrophication, and the introduction of exotic species. Many of these negative impacts are expected to be exacerbated in response to global climate change. To mitigate the effects of anthropogenic activities and preserve freshwater resources and ecosystem function, it is essential to understand how these activities affect aquatic communities and ecosystems. Research in our lab is dedicated to understanding how anthropogenic activities alter community structure and ecosystem processes, such as productivity, decomposition, and biogeochemical cycling, in freshwater ecosystems. Much of our research has focused on the impacts of aquatic organisms on basal food resources, community structure, and nutrient dynamics in fresh waters.
