Research Interests and Expertise

Dr. O’Reilly is holder of the Mollie Villeret Davis Professorship in Learning Disabilities and is Professor of Special Education. He coordinates the graduate training programs in Autism and Developmental Disabilities. Graduate coursework in autism is approved by the Behavior Analysis Certification Board. He is also Director of the Autism Spectrum Disorders Institute within The Meadows Center for Preventing Educational Risk. 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. Most of his current work focuses on the role of antecedent manipulations (Motivating Operations) in behavioral assessment and intervention. 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. A native of Ireland, he lectured in the Department of Psychology at University College Dublin for 10 years prior to joining The University of Texas at Austin in 2002.
