Biography

    Larry J. Siever is the director of the Special Evaluation Program for Mood and Personality Disorders, a Professor of Psychiatry, and Vice-Chair for VA Affairs at the Mount Sinai School of Medicine. He is also Director of the VISN 3 Mental Illness Research Education and Clinical Center and Chief of Psychiatry at the James J. Peters VA Medical Center. Dr. Siever is an internationally recognized leader in the field of personality disorder research. Throughout his career, his focus has been on the neurobiological substrates that underlie both borderline personality disorder and schizotypal personality disorder, and has published numerous articles and a book in this area. His present research employs neuroimaging techniques and cognitive enhancement to explore dopaminergic abnormalities in schizotypal personality disorder as part of the schizophrenia spectrum. His work in borderline personality disorder currently employs Positron Emission Tomography to identify specific receptor distribution in the brain that might underlie this pathology. He is also a well recognized teacher and clinician in the field of personality, as well as schizophrenia, affective, and impulse spectrum disorders.
