Research Overview

The goal of our research is to understand the molecular and circuit mechanisms underlying etiopathophysiologies of psychiatric disorders, such as schizophrenia and depression. In particular, we investigate how genetic risk factors and environmental factors, such as adolescent cannabis use and psychosocial stress, affect stress-related biological signaling mechanisms, including immune and inflammatory processes, leading to impairment of brain development and brain function that regulates cognitive and mood-related behaviors.

We hope our research ultimately identifies new therapeutic targets and biological markers for early intervention of these devastating conditions.
