Background

Dr. Hagopian received his Ph.D. in Clinical Psychology from Virginia Tech in 1991. He is a Board Certified Behavior Analyst, and Licensed Psychologist.  

He is Program Director of the Neurobehavioral Programs at the Kennedy Krieger Institute. This includes the Neurobehavioral Unit, which provides intensive inpatient treatment for individuals with intellectual disabilities, who exhibit self-injury, aggression, and other problem behavior. The NBU draws patients nationally and provides integrated behavioral and psychiatric treatment.

Dr. Hagopian’s clinical research focused on understanding and treating problems related to intellectual and developmental disabilities. The NIH has funded his translational research continuously since 2004 (and through to 2018). This research crosses disciplines and seeks to understand the interaction of biological and environmental factors in individuals with intellectual and developmental disabilities. This includes a research grant on behavioral deficits in autism, a neuroimaging study on the reward system in autism, evaluation of generalization of behavioral treatments, and most recently on delineating subtypes of automatic self-injury. Dr. Hagopian has published his research in 21 different peer-reviewed behavioral, medical, and psychiatric journals, including: the Journal of Applied Behavior Analysis, Journal of Child Neurology, Journal of Developmental and Physical Disabilities, American Journal on Mental Retardation, Behavior Therapy, Journal of Anxiety Disorders, Journal of Behavior Therapy and Experimental Psychiatry, Pediatrics, and Child and Adolescent Psychiatric Clinics of North America.
