My research focuses on food webs, biodiversity and functioning of aquatic ecosystems. I am particularly interested in their responses to anthropogenic stressors (e.g. eutrophication, acidification, brownification, atmospheric nitrogen deposition, etc.) and climate change.
My primary research goals are directed towards evaluating human and climate impact on ecological and biogeochemical processes using radionuclides as tracers. I have expertise in both terrestrial and aquatic ecosystems at various temporal and spatial scales.
My research focuses on the controls over ecosystem structure and functioning in streams, rivers, and watersheds. We study these systems to understand their condition as natural resources, but also as models to test general ecological and biogeochemical principles.
