Ran Barzilay, MD PhD, is an Assistant Professor of Psychiatry at Penn Medicine. Dr. Barzilay is a child and adolescent psychiatrist with background in translational neuroscience ranging from basic molecular neuroscience to clinical studies. He studies mechanisms that drive variability in development of youth growing up under environmental stress (exposome). His research integrates multimodal data in attempt to dissect the interplay of biological and environmental factors that explain patients' susceptibility versus resilience.
