Michael E. Wyde, Ph.D., D.A.B.T., manages and participates in multidisciplinary teams of NIEHS/NTP scientists to develop research programs to address a broad array of toxicological study needs for chemicals selected for study by the National Toxicology Program. This includes the design, analysis, interpretation, and integration of carcinogenicity, reproductive and developmental, genetic, and general toxicology studies. These research programs serve to identify hazards associated with chemical exposure and increase our understanding of the interaction between chemical exposure and the development of disease. These studies are published as NTP Technical Reports and peer-reviewed research papers in scientific journals and provide critical data for use in risk assessment for human exposure.
Wyde serves as the project leader for several chemicals including compounds that are used in consumer products, as food additives, as chemical intermediates, and environmental contaminants. He has a particular interest in chemical mixtures and herbal products, as well the application of dose-response modeling to NTP data for use in risk assessment, such as the determination of Benchmark Doses for carcinogenic and non-carcinogenic responses.
Wyde received a B.S. in biochemistry from North Carolina State University, Raleigh, North Carolina and a Ph.D. in toxicology from the University of North Carolina at Chapel Hill. He completed postdoctoral work at CIIT Centers For Health Research in Research Triangle Park, North Carolina.
