Research Summary

Dr. Abbeduto’s research at the UC Davis MIND Institute focuses on the development of language across the lifespan in individuals with neurodevelopmental disorders. His current projects focus on the factors accounting for variation in the course of language in children, adolescents, and young adults with fragile X syndrome, autism, or Down syndrome. These projects seek to identify the behavioral, biological, and environmental influences that shape language in these conditions.

Other projects focus on the development of methods to optimize language development through parent-mediated interventions and the role of telehealth technology in the delivery of these interventions.  Dr. Abbeduto’s research has been funded virtually continuously by the National Institutes of Health since 1984.  He is the editor of the American Journal on Intellectual and Developmental Disabilities, which is the flagship journal of the American Association on Intellectual and Developmental Disabilities.  Dr. Abbeduto is also Director of the NIH-funded Interdisciplinary Training Conference on Developmental Disabilities, which is designed to foster an interdisciplinary approach to research on neurodevelopmental disorders in the next generation of scientists.
