Principal Investigator

Marie Channell, PhD
Associate Professor
Dr. Channell's research focuses on the development of language, cognition, and social-emotional skills in individuals with Down syndrome or other neurodevelopmental disorders associated with intellectual disability (e.g., fragile X syndrome; autism spectrum disorder), particularly during middle childhood and adolescence. Her questions are framed by how skills in these domains work together to influence everyday communication in individuals with neurodevelopmental disorders. Dr. Channell earned her PhD in Developmental Psychology from the University of Alabama in 2012. Following her PhD, she spent 3 years as a post-doctoral fellow at the University of California, Davis MIND Institute, where she received interdisciplinary training in the Autism Research Training Program (NRSA T32, NIMH). She joined the faculty of Speech and Hearing Science at the University of Illinois at Urbana-Champaign in 2015.
