Research Interests

• Research experience and interests include understanding the ecological processes that govern freshwater and riparian productivity, spatial subsidies in freshwater foodwebs, biodiversity and community interactions, trophic interactions, salmonid feeding ecology and carrying capacity, and the restoration and management of freshwater and riparian ecosystems. My research focuses on three primary topics: role of marine nutrients and energy from salmon runs in regulating freshwater food webs, ecological linkages between fishless headwaters and downstream fish communities, and the role of forest and riparian vegetation and their management in governing food subsidies (aquatic and terrestrial invertebrates) for salmonids and other fishes.
