Dr. Parsons joined the Department of Anesthesiology in October, 2016, as an Assistant Professor in the Division of Research. He received his BS from the Department of Biochemistry at Virginia Polytechnic Institute and State University (VA Tech) in Blacksburg, VA and remains a devoted VA Tech Hokie. He earned his PhD from the Department of Biochemistry and Molecular Biophysics at Virginia Commonwealth University (VCU) in Richmond, VA. His post-doctoral training was in the neuroscience laboratories in the Department of Neurology at VCU. His first appointment was as a Research Associate in the Department of Anesthesiology (2006-2010) and most recently an Assistant Professor in the Department of Neurosurgery (2010-2016), both at VCU. He was also a fellow of the VCU Reanimation Engineering Science Center and the Johnson Center for Critical Care and Pulmonary Research. Dr. Parsons has a strong track record as PI and/or COI on Department of Defense and Office of Naval Research Combat Casualty Care focused research grants.
