Faculty Focus - Clement Hamani
Dr. Clement Hamani received his medical degree from Escola Paulista de Medicina in São Paulo in 1993 and went on to receive his PhD in Neurosciences from the same institution. He completed a Research and Clinical Fellowship in Functional Neurosurgery at the Division of Neurosurgery at Toronto Western Hospital. In 2008, he joined the Centre for Addiction and Mental Health as a Research Associate and became Assistant Professor at the University of Toronto Division of Neurosurgery. In 2013, he won the Ohye Award, awarded by the World Society for Stereotactic and Functional Neurosurgery (WSSFN) to promote clinical research in stereotactic and functional neurosurgery. He is currently Associate Professor at the Division of Neurosurgery and a Board Member and Chair of the Guidelines Committee at the American Society for Stereotactic and Functional Neurosurgery. His research focuses on the treatment of movement disorders, epilepsy, and psychiatric disorders.
