David M. Reif, Ph.D., joined the NIEHS in 2022 as Chief of the Predictive Toxicology Branch (PTB) in the Division of Translational Toxicology (DTT). In this role, he will leverage expertise of the branch in artificial intelligence / machine learning (AI/ML), data science, toxicogenomics, spatiotemporal exposures and toxicology, computational methods development, and new approach methods (NAMs) to advance predictive toxicology applications with partners across NIEHS, the interagency
Tox21 Program
and the
Interagency Coordinating Committee on the Validation of Alternative Methods
(ICCVAM).
Prior to joining NIEHS in 2022, Reif was a professor of bioinformatics at North Carolina State University, in the Department of Biological Sciences. His lab focused on integrated analysis of high-dimensional data from diverse sources to understand the complex interactions between human health and the environment and included trainees from degree programs in bioinformatics, genetics, toxicology, and statistics. Before North Carolina State University, David was a principal investigator (PI) with the U.S. EPA's National Center for Computational Toxicology. His efforts in research (
publications
), teaching, and outreach have been recognized with several honors, including the
Presidential Early Career Award for Scientists and Engineers
(PECASE), awarded by The White House as the highest honor bestowed by the United States government on science and engineering professionals in the early stages of their independent research careers. He has also been selected to serve on expert committees, including those for the National Academy of Sciences, the World Health Organization's International Agency for Research on Cancer, and the U.S. EPA Science Advisory Committee on Chemicals.
Reif earned his B.S. in biology (with a minor in finance) from the College of William and Mary, where he was a Monroe Scholar. He earned his M.S. in applied statistics and Ph.D. in human genetics from Vanderbilt University. He then completed postdoctoral training in exposure science and computational toxicology at the U.S EPA.
