Jason Stanko, Ph.D., serves as a Project Officer/Contract Officer's Representative in the Office of Program Operations in the Division of Translational Toxicology (DTT). Stanko assists with the administration and monitoring of contracts for toxicology studies and quality assessment activities. He aids in the design, conduct, interpretation, and reporting of DTT research to evaluate potential adverse effects of environmental substances with the aim of predicting potential health effects in humans.

Stanko received a B.S. in biochemistry from University of North Carolina at Chapel Hill and a Ph.D. in toxicology from the University of Alabama at Birmingham. Prior to joining the Program Operations Branch, he worked in the National Health Effects and Environmental Research Laboratory of the US EPA and in the Reproductive and Endocrinology branch of the National Toxicology Program Laboratory.
