Bradley Collins is a chemist and serves as a project officer in the Program Operations Branch for the National Toxicology Program (NTP). He manages contracted chemistry efforts in support of NTP toxicology studies and has served on study design teams and interagency working groups to provide technical assistance in the areas of chemistry and toxicokinetics. Collins also provides NTP with expertise in the design, direction and interpretation of toxicokinetic studies for AIDS therapeutics and other test articles and provides cheminformatics support to the NTP high throughput toxicology-screening program.

As a chemist, Collins is involved in the design, conduct, interpretation and reporting of NTP research and testing activities that investigate the toxicology of a variety of chemicals including high production volume chemicals, dietary supplements and nanoparticles. Over the past 20 years, Collins has served as the Project Officer for NTP chemistry support activities, which include chemical procurement, characterization and toxicokinetics. As part of those activities, Collins worked with the chemistry support contractor to develop the dose analysis method validation protocol currently used by the NTP.

Collins received his B.S. in Science and Environmental Change from the University of Wisconsin-Green Bay in 1979 and his M.S.P.H. in Environmental Chemistry from the University of North Carolina at Chapel Hill in 1984. In addition to his scientific duties, he has also served as Chair of the NIEHS Diversity Council, served on the NIEHS Quality Council and the on the Environmental Awareness Advisory Committee.
