He is a professor of biological sciences and his interests include aquatic ecology, food web energetics, and conservation. He is most interested in the effects of human activities on ecosystem function, fisheries, and water quality.

These include: contamination (by metals, pesticides, sewage), watershed alteration (land use, impoundments, irrigation) and exotic species introductions. His laboratory has made important contributions of the development of modeling techniques based on isotopic tracers and their application in aquatic science and management. Poster
