Bio

George P. Cobb serves as division leader for Environmental Sciences and Toxicology and professor of environmental chemistry and analytical toxicology.  He received his Ph.D. in Chemistry from the University of South Florida in 1989 and his B.S. in Chemistry from the College of Charleston in 1982.  Dr. Cobb was an associate professor in the Department of Environmental Toxicology at The Institute of Wildlife and Environmental Toxicology (TIWET) at Clemson University from 1995-1997 and an adjunct professor of environmental studies at Western Washington University from 1988 – 1990.  Dr. Cobb has a history of research into trophic transport of pesticides and hazardous wastes in ecosystems.  His research group's activities currently emphasize: 1) explosives detection at environmentally relevant concentrations in abiotic and biotic systems; 2) uptake and toxicity of nanoparticles in aquatic systems; 3) sensor designs for airborne toxicants and pathogens.  Dr. Cobb formerly served as member of the Society of Environmental Toxicology and Chemistry (SETAC) Committee and on the Board of Directors as Annual Meeting Program Chair.  Dr. Cobb has also served on the Executive Committee for the American Chemical Society: Environmental Division and on the Editorial Board of Environmental Toxicology and Chemistry, and he continues to provide peer review for this publication as well as other scientific journals including Environmental Health Perspectives, Chemosphere, Environmental Pollution, Journal of Wildlife Diseases, Journal of Nematology and Soil Biochemistry.
