Title: The U.S. Environmental protection agency’s risk assessment of genetically engineered microorganisms for Biofuels, Bioenergy, and Bioproducts


Dr. Gwendolyn McClung is a microbiologist with more than 25 years of experience in the Biotechnology Program in EPA’s Office of Pollution Prevention and Toxics (OPPT) conducting ecological hazard assessments and risk assessments of genetically engineered (GE) microorganisms reviewed under the Toxic Substances Control Act (TSCA). GE microorganisms reviewed under TSCA include a variety of applications such as biofuel production, biomass conversion, wastewater treatment, bioremediation, biofertilizers, and biosensors in addition to production of enzymes, specialty chemicals, and commodity chemicals. In recent years reviews have included cyanobacteria and eukaryotic microalgae (microalgae) submissions used in both closed systems (e.g., photobioreactors and fermentors) and in open pond field tests.

Gwen received her Bachelor’s degree and Master’s degree in Agronomy (Soil Science) from the University of Maryland, College Park, and her Ph.D. in Soil Science (Soil Microbiology) from the University of California, Riverside. Gwen did a post-doctoral fellowship at the Ohio Agricultural Research & Development Center in Wooster, OH and a post-doctoral fellowship at the USDA Beltsville Agricultural Research Center in Beltsville, MD before joining EPA.
