Joseph G. Verbalis, MD is a Professor of Medicine, Chief of Endocrinology and Metabolism, and Co-Director of the Georgetown-Howard Universities Center for Clinical and Translational Science at Georgetown University. He graduated from Princeton University with an AB in chemistry in 1971, and received an MD from the University of Pittsburgh in 1975. He completed his residency training at the Hospital of the University of Pennsylvania from 1975-1978 and his fellowship training in endocrinology and metabolism at the University of Pittsburgh from 1978-1980. Dr. Verbalis was a faculty member at the University of Pittsburgh from 1980 through 1995, and then relocated to Georgetown University in 1995. Dr. Verbalis has published more than 285 journal articles and book chapters related to the neuroendocrine regulation of the hormones vasopressin and oxytocin, and disorders of body fluid homeostasis. He authors the chapters on vasopressin and water metabolism in major textbooks of endocrinology, nephrology and neuroscience and is a regularly invited speaker at national and international meetings on neuroendocrinology and body fluid homeostasis. Dr. Verbalis’ research has been funded by the National Institutes of Health for the last 25 years, and has concentrated on mechanisms underlying adaptation to hyponatremia, renal escape from vasopressin, osmotic regulation of hypothalamic gene expression, sex differences in physiology and pathophysiology, exercise-associated hyponatremia, and clinical use of vasopressin receptor antagonists. In 2007 he was the awarded the Berthold Medal by the German Endocrine Society for outstanding scientific achievement in endocrinology by individuals who have excelled in combining both basic and clinical research. From 2003 to 2010 Dr. Verbalis directed the Georgetown-MedStar General Clinical Research Center. Under his co-leadership, Georgetown and Howard Universities were awarded a Clinical and Translational Science Award in 2010 to establish the Georgetown-Howard Universities Center for Clinical and Translational Science.
Thomas A. Mellman, MD is Professor and Vice-Chair for Research for the Department of Psychiatry at Howard University and Associate Program Director for the GCRC. He has previously held faculty appointments at the University of Miami and Dartmouth and received training at the NIMH Division of Intramural Research Programs. Dr. Mellman has had continuous funding as PI on federal research grants since 1991 including a VA Merit award, and R01 and K24 awards from NIMH. His primary research interest has been the role of sleep in posttraumatic stress disorder (PTSD) and the early aftermath of trauma and he recently initiated study of the relationship of PTSD to nocturnal blood pressure in young adult African Americans. His additional research interests with resulting publications include other aspects of the psychobiology and treatment of PTSD and evidence-based practices in psychopharmacology. He has a consistent track record of mentoring junior investigators and interdisciplinary collaboration. He has been a member of NIMH IRGs for Violence and Traumatic Stress, and Interventions and has served on several review committees for the NIH Roadmap and the Department of Defense research program. Dr. Mellman was a member of committees for developing consensus treatment guidelines for PTSD, text revision of the DSM-IV, and the Institute of Medicine Committee for the treatment of PTSD.
