Dr. Robert Stillman is a leading researcher in the assessment communication in children with Autism Spectrum Disorder (ASD), deafblindness, and other severe disabilities. His interests focus on preverbal communication and the social and cognitive abilities which underlie the transition to speech and language. He also is active in developing intervention approaches with children at the preverbal level. Dr. Stillman developed the Callier-Azusa Scale, a widely used instrument for assessing the developmental skills of children with deafblindness and has been the principle investigator on a number of U.S. Department of Education grants designed to assist teachers and therapists serving children with severe disabilities. He is a frequent consultant and collaborator on grants related to severe disabilities. Dr. Stillman’s early work focused on the neurophysiology of audition, including how single cells code binaural sounds and investigations of the frequency-following response (FFR) in humans. Dr. Stillman serves on the advisory board of the Urban Speech and Language Initiative and has served as a reviewer for articles in a number journals. Dr. Stillman received his bachelor’s degree from Union College and his PhD from Syracuse University.
