Dr. Barzilay is a child and adolescent psychiatrist with background in translational neuroscience ranging from basic molecular neuroscience to clinical studies. He studies a broad range of brain mechanisms that affect developmental psychopathology. Specifically, his work focuses on the effects of developmental stress on psychopathology, attempting to dissect the interplay of host and environmental factors in underpinning a patient’s susceptibility versus resilience. Dr. Barzilay is also interested in studying developmental trajectories of brain disorders that involve social cognition deficits such as autism and schizophrenia.
