Jack McClellan, MD

Personal Statement

I am a Professor in the Division of Child Psychiatry, Department of Psychiatry and Behavioral Sciences, at the University of Washington, and the Medical Director of Child Study and Treatment Center, the State Hospital for children and adolescents in Washington State. My primary research focus addresses the genetics of neuropsychiatric disorders.  Our research supports that a substantial portion of neuropsychiatric disease, including schizophrenia and autism, stems from individually rare deleterious mutations in genes important for brain development.My clinical research addresses the diagnosis and treatment of early-onset psychotic illnesses.  I authored the American Academy of Child and Adolescent Psychiatry’s diagnostic and treatment guidelines for schizophrenia and bipolar disorder.
