John Wambaugh, Ph.D., is a principal computational exposure and toxicokinetic research scientist at UL Research Institutes’ Chemical Insights. He leads research in in vitro-in vivo extrapolation (IVIVE), toxicokinetics, and exposure science, providing expertise in applied statistics, machine learning, and new approach methods (NAMs), while developing mathematical models for chemical safety assessment.

Before joining Chemical Insights, John worked for over 16 years as a research physical scientist focused on computational toxicology and exposure. In this role, he co-led a project that provides high-throughput exposure estimates for thousands of chemicals and developed a widely-used R package that can estimate the concentration of a chemical that would lead to a biological response. He has authored over 100 peer-reviewed publications, mentored 18 trainees, and served as a contracting officer’s representative for several federal research contracts focused on chemical toxicity and human exposure modeling. John co-founded and was the first president of the Society of Toxicology’s Exposure Science Specialty Section, organizing over 30 symposia on new approach methods.

He holds a Ph.D. in Physics and a Master of Science in Computer Science from Duke University, a Master of Science in Physics from Georgia Tech, and a Bachelor of Science in Physics from the University of Michigan.
