Rachel Yehuda, PhD


Rachel.Yehuda@va.gov and Rachel.yehuda@mssm.edu

Rachel Yehuda joined the Psychiatry Department in 1991, where she is now Professor and Vice Chair for Veterans Affairs.  She received her Ph.D. at the University of Massachusetts at Amherst, MA and completed post-doctoral work at Yale Medical School.  Dr. Yehuda is the Mental Health Patient Care Center Director and Director of the Laboratory of Clinical Neuroendocrinology, Neurochemistry, and Molecular Biology Lab at the James J. Peters VAMC.  Dr. Yehuda was the first to articulate the neurobiology of PTSD by demonstrating a novel mechanism – enhanced glucocorticoid receptor sensitivity.  Her observations provided a roadmap for understanding why people respond so differently following trauma exposure. Dr. Yehuda’s lab developed a novel in vitro cell model to examine the dynamics of glucocorticoid receptor responsiveness in cultured lymphocytes, and was the first to publish a genome-wide expression study in PTSD that confirmed the involvement of molecular glucocorticoid regulators, leading to an approved patent being developed as diagnostic blood test.  Dr. Yehuda and colleagues were also first to publish epigenetic findings in PTSD and apply the observations to intergenerational effects and treatment. She has recently been elected to the National Academy of Medicine as a result of her pioneering discoveries in the study and treatment of PTSD.

Throughout her career, Dr. Yehuda has received numerous grants from the National Institute of Mental Health, the Department of Defense, the Veterans Administration and various Foundations such as Lightfighter Trust, The American Foundation for Suicide Prevention, and the Brain and Behavior Research Foundation, and was more recently awarded funding from the Multidisciplinary Association for Psychedelic Studies to test the efficacy of MDMA-assisted psychotherapy in combat veterans with PTSD. Dr. Yehuda’s laboratory has produced over 450 peer-reviewed publications and book chapters as well as 18 books and edited volumes.  Her work has been featured in several documentaries and lay media.

Philip Szeszko, PhD

Associate Professor


Philip R. Szeszko, Ph.D., is Associate Professor of Psychiatry at the Icahn School of Medicine at Mount Sinai (Investigator Track) and a Psychologist at the James J. Peters VA Medical Center. Dr. Szeszko joined the Yehuda Lab in 2016 to help expand efforts in neuroimaging and integration with molecular biology and endocrine studies.

A major goal of this work focuses on the identification of magnetic resonance imaging predictors of treatment response to cognitive processing therapy in PTSD. He has also been leading efforts to better understand how deviations in the normal trajectory of white matter may contribute to accelerated aging in PTSD using neurite orientation dispersion and density imaging (NODDI). Dr. Szeszko has also focused on better understanding the role of hippocampal subregions in the pathogenesis of PTSD and their relationship to alterations in cognition and mood. His interest in trauma work is driven by his belief that such studies can be used to better understand neural mechanisms of risk and resilience to many neuropsychiatric disorders with the ultimate goal of identifying successful treatments.

Dr. Szeszko has received grant funding from the National Institute of Mental Health, DANA Foundation, Brain and Behavior Research Foundation, Obsessive-Compulsive Foundation and American Foundation for Suicide Prevention.  He has authored or co-authored over 130 peer-reviewed manuscripts and sits on the Editorial Boards of Progress in Neuro-psychopharmacology and Biological Psychiatry and Schizophrenia Bulletin.
