I’m an aquatic biologist and community ecologist, principally interested in how environmental contexts shape biological communities and influence ecosystem functioning. I am primarily an empiricist, combining experiments with field surveys to test and develop theory, and to address environmental problems. My key expertise lies in the mechanisms and impacts of eutrophication, climate change and biological invasions in aquatic ecosystems and fringing ecotones.
