Dr. Marmar’s research focuses on understanding, preventing, diagnosing, and treating post-traumatic stress disorder (PTSD) and related conditions. For more than four decades, his work has examined the impact of traumatic stress in military personnel, veterans, police officers, and civilians. His research has advanced understanding of the biological and psychological factors that influence why some individuals develop PTSD following trauma while others remain resilient. Using approaches that include blood biomarkers, neuroimaging, psychotherapy, and pharmacotherapy, Dr. Marmar has worked to identify more precise ways to detect PTSD, predict risk and resilience, and improve treatment. His research has helped advance the field toward precision medicine approaches that use biological and clinical information to better understand individual differences in trauma-related disorders.

Dr. Marmar is the Peter H. Schub Professor of Psychiatry at NYU Grossman School of Medicine, where he serves as Director of the Center for Precision Medicine in Alcohol Use Disorders and Post-Traumatic Stress Disorder and Executive Director of the Steven A. Cohen Military Family Center. Prior to joining NYU, he was Professor and Vice Chair of Psychiatry at the University of California, San Francisco and Associate Chief of Staff for Mental Health and Director of the PTSD Research Program at the San Francisco VA Medical Center.

He earned his BSc and MD from the University of Manitoba and completed his psychiatry residency and a fellowship in neuropharmacology at the University of Toronto, followed by fellowship training in traumatic stress and grief at UCSF.
