 About  |  Publications 


Dr. Shen received a bachelor’s degree in cognitive psychology from Marquette University in Milwaukee, WI. He received an M.S. and a Ph.D. in behavioral neuroscience from Auburn University in Auburn, AL. Prior to joining FDA, Dr. Shen was a postdoctoral scholar at the University of Kentucky's Sanders-Brown Center on Aging (2016-2018) and a postdoctoral fellow at FDA’s National Center for Toxicological Research (NCTR) through the Oak Ridge Institute for Science and Education (ORISE) (2019). Presently, he is a staff scientist in NCTR’s Division of Neurotoxicology.

Research Interests

Dr. Shen’s research focuses on characterizing the neurobehavioral and neurovascular consequences of drugs, heavy metals, and other compounds with potential neurotoxicity. In particular, his work aims to elucidate the connection between neurovascular dysfunction and changes in cognitive processes. His laboratory utilizes diverse methods to answer regulatory toxicology questions, which range from live-cell confocal microscopy and protein assays to neurobehavioral assays and complex cognitive tasks. Currently, Dr. Shen is collaborating with colleagues to assess potential developmental neurotoxicity of cannabidiol (CBD) as well as potential neuroimmune effects of developmental CBD exposure.
