Biography
Ellen J. Hoffman, M.D., Ph.D. was appointed as Assistant Professor in the Child Study Center in July 2015. Ellen is a child psychiatrist, psychiatric geneticist and neurobiologist, and a graduate of the Investigative Medicine PhD Program at Yale, who specializes in the functional analysis of genes in neurodevelopmental disorders. The Hoffman laboratory conducts translational research aimed at understanding the biological mechanisms underlying autism spectrum disorders and discovering new pharmacological treatments. Ellen's research focuses on investigating the function of genes that are strongly associated with autism to determine how disruption of these genes alters brain development and the neural circuits underlying simple behaviors. The long-term goal of her research is to use this gene-based approach to identify relevant biological pathways and novel pharmacological treatments that target these pathways. Ellen also works clinically as a child psychiatrist and as an attending supervising Yale child psychiatry fellows.
