Dr. O'Reilly is the Audrey Rogers Myers Centennial Professor in Education, Professor of Special Education, and Chair of the Department of Special Education. He is a doctoral level Board Certified Behavior Analyst (BCBA-D) and Licensed Behavior Analyst (LBA). He coordinates (with Terry Falcomata) the graduate training programs in Autism and Developmental Disabilities. Graduate coursework in autism is approved by the Behavior Analysis Certification Board. His research focuses on the functional assessment and treatment of severe challenging behavior and interventions to promote generalization and maintenance of skills with children with autism and developmental disabilities. He has a strong interest in working with culturally diverse populations (particularly protecting and encouraging indigenous cultures and languages) and examining how behavioral interventions (and interventionists for that matter) must adapt to be respectful and supportive of diversity.
