Hedda Meadan is a professor at the Department of Special Education at the University of Illinois at Urbana-Champaign. Dr. Meadan’s areas of interest include social-communication skills and challenging behavior of young children with autism and other developmental disabilities and intervention methods to enhance these spheres of functioning. Dr. Meadan and her team use a cascading intervention model in which they train and coach, via telepractice, natural change agents (e.g., family members, service providers, behavior analysts) to use evidence-based strategies to promote social-communication skills of children in the natural environment.
