Bio

Leonard Abbeduto, PhD, is the Director of the MIND Institute, the Tsakopoulos-Vismara Endowed Chair, and Professor of Psychiatry and Behavioral Sciences at the University of California, Davis. Dr. Abbeduto’s research is focused broadly on the development of language across the lifespan in individuals with neurodevelopmental disorders and the family context for language development.  Dr. Abbeduto has published more than 190 articles, chapters, reviews, and books on fragile X syndrome, autism, Down syndrome, intellectual disabilities, and child development. His program of research has been funded nearly continuously by NIH since 1985. His current research is focused on understanding variation in language outcomes in various neurodevelopmental disorders, the measurement of treatment effects in clinical trials, and the use of distance technology in behavioral treatment. He serves as PI/PD of the NICHD-funded MIND Institute Intellectual and Developmental Disabilities Research Center (IDDRC), which provides core support to more than 70 projects and 40 scientists at the UC Davis MIND Institute. Dr. Abbeduto has received numerous awards, including the Emil A. Steiger Award for Distinguished Teaching from the University of Wisconsin-Madison, the Faculty Stewardship Award from the University of California, Davis, the Enid and William Rosen Research Award from the National Fragile X Foundation, and Edgard Doll Award for Distinguished Research Contributions from Division 33 of the American Psychological Association. He earned his PhD in psychology from the University of Illinois at Chicago in 1982. He came to UC Davis 2011 after 24 years on the faculty at the University of Wisconsin-Madison.
