Research & Publications
My research interests revolve around the interface of psychiatry, neurology, and genetics. A major focus is on the etiology, pathogenesis, and psychiatric aspects of neurodegenerative disorders affecting the cerebellum and basal ganglia, including Huntington’s disease, Huntington’s disease-like 2 (discovered by our group), and the cerebellar ataxias. A second emphasis is on the genetic etiology and pathogenesis of schizophrenia, including the role of rare mutations of major effect, the potential utility of induced pluripotent stem cells as disease models, and novel approaches to mutation detection. We are particularly interested in the etiologic and pathogenic properties of unstable DNA, RNA toxicity, and bidirectional transcription. My clinical interests include schizophrenia, affective disorders, and neuropsychiatry.
