Welcome to the Lewis Lab in the Department of Psychiatry and Behavioral Sciences

We are interested in using animal models and human studies to understand brain regions and circuits important for social cognition, aggression, and neurocognition in neurodevelopmental and neurocognitive disorders. Our goal is to identify novel ways to improve functioning in patients with conditions such as schizophrenia, autism, and Alzheimer’s Disease. Read more about our research here.

Our lab is affiliated with many departments, centers, and programs at Vanderbilt University Medical Center and Vanderbilt University.
