Dr. Volk’s research utilizes a translational approach for studying the pathogenesis and pathology of schizophrenia. He develops and tests hypotheses involving neural circuitry abnormalities in postmortem human brain tissue, and tests their plausibility through cell-type-specific genetic manipulations in animal models. These experiments are designed to identify novel treatment targets for schizophrenia. Integrating his high-quality scientific training in neuroscience and his clinical training as a psychiatrist, Dr. Volk has developed a national reputation in this area. In 2009, he received a National Institute of Mental Health (NIMH) K08 mentored clinical scientist development award titled Schizophrenia and Endocannabinoid Effects on Inhibitory Circuitry. This work led to the funding of his current NIMH R01 Disrupted Ontogeny of Cortical GABA Neurons in Schizophrenia, which examines disturbances in prefrontal cortical inhibitory neurons in schizophrenia. Dr. Volk also serves as a co-investigator of the National Institute of Health (NIH) Brain and Tissue Repository Contract and has also made important contributions as a co-investigator to the new NIMH Conte Translational Mental Health Research Center. His accomplishments have been recognized nationally, including his receipt of the NIMH Outstanding Resident Award in 2006, the American Psychiatric Association’s Research Colloquium for Junior Investigators Award in 2007, travel awards from both the American College of Neuropsychopharmacology (2010) and the International Congress on Schizophrenia (2011), and the Hamilton Family Award for Basic Neuroscience Research in Psychiatry in 2012. He has also served as an ad hoc reviewer for NIH Study Sections and is a member of the editorial board of Neurobiology of Disease. His research has been published in top-tier journals including JAMA Psychiatry (Archives of General Psychiatry), the American Journal of Psychiatry, and Biological Psychiatry.
