Muhammad O. Chohan, MD, is an Assistant Professor of Clinical Psychiatry within the Division of Child and Adolescent Psychiatry at the Columbia University Irving Medical Center (CUIMC) and the New York State Psychiatric Institute (NYSPI).

Dr. Chohan obtained his medical degree in Pakistan. During medical school, he completed an internship at CUIMC and NYSPI where he examined the relationship between interneuron dysfunction and psychosis. After graduating from medical school, he did postdoctoral work on dopamine and glutamate abnormalities in psychosis and obsessive-compulsive disorder at CUIMC and NYSPI. Dr. Chohan hopes to draw on his clinical background and research training to develop new approaches to understanding and treating the cognitive, motivational, and motor abnormalities that are characteristic of neuropsychiatric disorders.
