Research Interests and Expertise
A native of Ireland, Dr. Mark O’Reilly joined the Department of Special Education in 2002. O'Reilly currently coordinates the graduate training programs in autism and developmental disability. The Behavior Analysis Certification Board preapproves program coursework. He is interested in the design, implementation, and evaluation of evidence-based and culturally sensitive services for students with autism and related developmental and physical disabilities and for their families.
