About  |  Office Scientists


Dr. Bradley J. Schnackenberg received his B.S. in Cell Biology from the University of Kansas in 1991 and completed his Ph.D. in Physiology and Cell Biology at the University of Kansas in 1998. Between 1998-2003, 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. In 2004, Dr. Schnackenberg joined the faculty in the Department of Pediatrics at the University of Arkansas for Medical Sciences and conducted 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 1) coordinating the scientific review and approval of research protocols to ensure alignment with FDA and NCTR programmatic objectives, and 2) advised research investigators on scientific policy including human subject research, animal care and use, and technology transfer. He serves as an alternate member to the FDA Research Involving Human Subjects Committee (RIHSC) and serves as the liaison between NCTR and the Center for Tobacco Products (CTP). In 2017, Dr. Schnackenberg was named Associate Director of NCTR’s Office of Scientific Coordination.

The mission of the Office of Scientific Coordination (OSC) is to enable the research mission of NCTR/FDA by providing the professional support necessary to conduct toxicological studies.  The support functions of the 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 (COR) for the animal care, pathology, and laboratory equipment maintenance and repair contracts. The OSC also provides program management for the Interagency Agreement between FDA and the National Toxicology Program (NTP), as well as the Performance Agreement between NCTR and CTP.
