About  |  Office Scientists


Dr. Bradley J. Schnackenberg is the Associate Director of the Office of Scientific Coordination (OSC) at FDA’s National Center for Toxicological Research (NCTR). He received a B.S. in cell biology and a Ph.D. in physiology and cell biology from the University of Kansas. He was a Lineberger Comprehensive Cancer Center postdoctoral fellow in the Program in Molecular Biology and Biotechnology at the University of North Carolina at Chapel Hill before joining the faculty in the Department of Pediatrics at the University of Arkansas for Medical Sciences and conducting research within the Lung Cell Biology Laboratory at the Arkansas Children’s Hospital Research Institute. In 2008, he was selected into the inaugural class of the FDA commissioner’s fellowship program and subsequently joined NCTR’s Office of Research in 2010. During his tenure in the Office of Research, Dr. Schnackenberg was responsible for coordinating the scientific review and approval of research protocols to ensure alignment with FDA and NCTR programmatic objectives and advising research investigators on scientific policy including human subject research, animal care and use, and technology transfer. He served as an alternate member to the FDA Research Involving Human Subjects Committee. In 2017, Dr. Schnackenberg was named Associate Director of OSC and currently serves as the liaison between NCTR and the Center for Tobacco Products (CTP).

The mission of OSC is to enable the research mission of NCTR/FDA by providing the professional support necessary to conduct toxicological studies. The support functions of OSC include Veterinary Services and Microbiology Surveillance, Toxicology Program Support, Experimental Liaison Support, the Analytical Chemistry Group, the Statistical Support Group, the NCTR-ORA Nanotechnology Core Facility, and Contract Officer Representatives for three onsite contracts that provide support in the areas of animal care, pathology, and laboratory equipment maintenance and repair. The OSC also provides program management for the Performance Agreement between NCTR and CTP.
