Dr. John F. Wambaugh is an EPA research physical scientist and the co-leader of the ExpoCast project. Dr. Wambaugh received a BS in physics from the University of Michigan, Ann Arbor, an MS in physics from Georgia Institute of Technology, an MS in Computer Science, and a Ph.D. in physics from Duke University. He was a Post-Doc from the National Center for Computational Toxicology, Durham, NC in Statistical Analysis of Biological Models. Dr. Wambaugh’s areas of active research include high throughput methods for exposure, toxicokinetics, and toxicology; Bayesian statistics; and biostatistics. He co-leads the EPA ExpoCast project and is a member of the ToxCast team. His research on these projects focuses on predicting human chemical effects and exposures using in vitro laboratory measurements and computer simulations and rigorously evaluating these predictions using statistical methodology.
