Dr. Diane Chugani a Professor of Communication Sciences and Disorders, with a joint appointment in the Department of Chemistry and Biochemistry, at the University of Delaware. Previously, she was Professor of Pediatrics at Wayne State University, Chief, Division of Clinical Pharmacology and Toxicology, Founder and Executive Director of the University Pediatricians Autism Center, and Director of the Translational Imaging Laboratory at Children’s Hospital of Michigan.

Dr. Chugani is a neuropharmacologist, and her research over 23 years at Wayne State University focused on brain mechanisms (neuroimaging with PET and MRI) and therapy (drug trials) in children with neurodevelopmental disorders, particularly autism and epilepsy, funded by NINDS and NICHD (including an NIH Autism Center of Excellence Network grant).  Four years ago, Dr. Chugani was recruited as a CTR Scholar to Nemours/AI Dupont Hospital for Children with a joint appointment at University of Delaware.

Following her move in September 2018 to a full time faculty position at the University of Delaware, Dr. Chugani has been focusing more in depth on biological mechanisms in language development. She has been collaborating with the faculty at UD interested in language development to explore physiological mechanisms that may underlie different aspects of language learning. She is taking a team approach with colleagues in the Communication Sciences and Disorders program at the University of Delaware and an expert on immune response to chronic stress at UCLA to address the “word gap” problem by exploring potential biological underpinnings of language related to chronic stress in low socioeconomic status, minority families.
