Research Interests

My primary research interests center on the identification of anthropogenic organic pollutants and the elucidation of their sources, fate, bioavailability and effects on ecosystems. Also the fate and consequences of microplastics and associated chemicals, e.g. polymer additives, in aquatic systems.

Education

• B.S. Biology, B.A. Chemistry, Wayne State University, 1979
• Ph.D., College of William and Mary, 1983

Specific Projects & Interests

• Organic contaminants in organisms, including fishes of Virginia waters.
• Identification of pollutants released via the water, air and to soil following sewage sludge (biosolids) applications and associated effects.
• Bioavailability of sludge-associated chemicals to terrestrial and aquatic organisms.
• Sources, analysis, fate and effects of brominated flame retardants and non-ionic detergents in the environment.
• Consequence of plastic debris in terrestrial & aquatic environments
