Translational Toxicology Division

Scott Masten, Ph.D., D.A.B.T., is Director of the Office of Portfolio Strategy (OPS) within the Division of the Translational Toxicology at the National Institute of Environmental Health Sciences (NIEHS). His primary responsibility is implementing a strategic research portfolio that efficiently and effectively leverages the breadth of Divisional scientific capabilities and advances the scientific mission of the DTT. Other important activities within the OPS include portfolio, program and project management, analysis and evaluation, and coordination of priority scientific initiatives within the Division.

In research prioritization and planning, Masten actively interfaces with a variety of stakeholders on public health issues of national and international significance. He engages with scientific advisory committees, federal and state agencies, commercial entities and advocacy organizations. He represents the NIEHS and NTP on interagency coordinating groups focused on a range of topics including disaster research and dietary supplements, and the National Science and Technology Council (NSTC) Sustainable Chemistry Strategy Team.

Masten is a Diplomate of the American Board of Toxicology and has broad research interests in toxicology testing strategies, predictive toxicology, safer alternatives, and regulatory decision-making. Masten received a B.S. in Marine Biology from the University of North Carolina at Wilmington and his Ph.D. in Pharmacology and Toxicology from the University of Florida. He came to NIEHS in 1995 for post-doctoral training in the Laboratory of Computational Biology and Risk Analysis and joined the NIEHS as a Research Fellow in 1998.
