Dr. Hagopian received his Ph.D. in Clinical Psychology from Virginia Polytechnic Institute and State University in 1991. He completed a pre-doctoral internship at the Kennedy Krieger Institute, and in the Department of Pediatrics at Johns Hopkins University School of Medicine. He is a Board Certified Behavior Analyst, and Licensed Psychologist. Dr. Hagopian has been called upon by state agencies, education departments, disability service organizations, advocacy organizations, professional organizations, States Attorneys General, and the U.S. Department of Justice for guidance and consultation on matters related to persons with autism and intellectual disabilities. This work includes the development of standards for treatment, position statements, best practice guidelines, and expert consultation.
Many children and adults with intellectual disabilities, autism or other neurobehavioral disorders display severe behavior problems such as self-injury, aggression, or property destruction. The Neurobehavioral Unit (NBU) at Kennedy Krieger Institute provides a continuum of care for these individuals that includes a 16-bed inpatient program, outpatient program, and intensive outpatient services. The primary approach used is Applied Behavior Analysis, characterized by the application of principles of behavior derived through laboratory research, the objective measurement of behavior, and the systematic analysis of relations between behavior and environmental events. The NBU draws nationally, and is recognized as the premiere program in the nation for providing intensive behavioral treatment to individuals with severe behavior disorders and developmental disabilities as well as for offering advanced training in applied behavior analysis.
The individuals served on the NBU frequently present rare behavior disorders that require innovative treatment approaches, so the NBU faculty and staff must constantly design new assessment and treatment procedures to meet the varied needs of their patients. Dr. Hagopian's main research interests are in assessment and treatment of self-injurious behavior, severe behavior disorders, anxiety disorders, and the application of operant learning paradigms to examine clinical problems including austism and anxiety. His research has been supported by grants from the National Institutes of Health; and has been published in 14 different peer-reviewed journals, including behavioral, interdisciplinary, international, and medical/psychiatric journals.
