Photo Description


Stream and River Ecology, Fisheries Science, Food Webs, Ecosystem Ecology

Aquatic and terrestrial food webs are linked by the exchange of nutrients, organic matter, and the movements of living organisms. The primary focus of my research is to understand how changes to biodiversity (e.g., species extirpations, biological invasions) alter exchanges of resources between land and water. To reveal the underlying mechanisms that shape the structure and function of aquatic ecosystems, and to identify effective management and conservation measures, I use a combination of community- and ecosystem-level approaches, conduct manipulative & natural field experiments, and modeling tools. If you have an interest in stream ecology, fisheries management, or the science of recreational fishing, please contact me.
