Eric Courchesne is Professor of Neurosciences in the School of Medicine at the University of California San Diego (UCSD) and Director of the UCSD Autism Center of Excellence. He is a leading expert on brain structural and functional abnormalities associated with autism. His research aims to identify biobehavioral markers of autism that will allow for earlier diagnosis and treatment leading to better clinical outcomes by integrating behavioral, developmental, genetic, neuroanatomical and neurofunctional findings. Research includes MRI studies, which have identified structures that are abnormal at infancy in autism and elucidated patterns of abnormal growth from infancy through adulthood. His MRI study of longitudinal development in ASD during the first years of life was named one of the Top Ten Autism Research Studies of 2010 by the IACC and his fMRI study of ASD toddlers was named one of the Top 10 of 2011 by the IACC. Current functional brain imaging techniques have established links between autistic symptoms in infants and toddlers and the brain sites responsible for them. Dr. Courchesne’s studies of brain tissue have discovered in children with ASD 67% excess numbers of prefrontal neurons, dysregulation of genetic mechanisms that control neuron numbers and patterning, and cellular and laminar defects in the frontal cortex. His studies have resulted in nearly 200 publications with an overall impact factor that is among of the highest in the autism field as determined by the ISI Web of Knowledge. His research has been published in JAMA, Science, Lancet and the New England Journal of Medicine and is supported through grants from NIMH, NINDS, NICHD, Autism Speaks, and the Simons Foundation.
