Biography

Dr. Bhat is an Assistant Professor in the Department of Psychiatry at the University of Toronto. He is currently a staff psychiatrist based at two Depression Centres: The Centre for Depression and Suicide Studies at St. Michael’s Hospital and the Poul Hansen Depression Centre at Toronto Western Hospital. At St. Michael’s Hospital, he is the Director of the Interventional Psychiatry Program which offers novel psychopharmacological (e.g. IV ketamine/other anesthetic agents), neurostimulation (e.g. rTMS, ECT, emerging neurostimulation modalities) and digital therapeutic (mobile-based monitoring and interventions) interventions for Mood and other Disorders. At Toronto Western Hospital, he has a focus on invasive neurostimulation (Deep Brain Stimulation and Invasive Brain Mapping) and is currently leading a study comparing ECT to IV Ketamine for Treatment-resistant Depression. Dr. Bhat collaborates closely with anesthesia, imaging, informatics, neurology and neurosurgery to offer emerging and procedural interventions for psychiatric disorders, his research program aims to understand treatment-response with these emerging interventions.
