I am Associate Professor with Tenure of Psychiatry and Neuroscience, and Director of the Depression and Anxiety Center for Discovery and Treatment (DAC) at the Icahn School of Medicine at Mount Sinai (ISMMS). My program of research utilizes molecular, neuroimaging, and experimental therapeutics approaches aimed at elucidating the fundamental mechanisms underlying stress-related disorders in humans, including major depressive disorder (MDD), posttraumatic stress disorder (PTSD) and anxiety disorders. The overall goal of my research is to advance the treatment of stress-related disorders through an enhanced understanding of disease pathogenesis and therapeutic mechanisms of action. Dennis S. Charney is an American biological psychiatrist and researcher, with expertise in the neurobiology and treatment of mood and anxiety disorders. He is the author of Neurobiology of Mental Illness, The Physician's Guide to Depression and Bipolar Disorders and Molecular Biology for the Clinician, as well as the author of over 600 original papers and chapters.
