Research & Clinical Interests
Dr. Tassé’s research and clinical interests are in the area intellectual disability (ID), autism spectrum disorder (ASD) and related neurodevelopmental disorders. His research has been focused on the co-occurrence of ID or ASD and psychiatric disorders or problem behavior, understanding and measuring adaptive behavior, test development, technology applications to enhancing health, independence, and personal autonomy, and the concept of support needs. His recent research has also centered on the study of the health and well-being of persons with ASD, ID and other related neuordevelopmental disorders. Dr. Tassé’s clinical interests include the diagnosis of intellectual disability, the assessment and treatment of problem behavior and psychiatric disorders in individuals with ID or ASD. He does some forensic work around the determination of intellectual disability in capital cases.
