Research Summary

The goal of our research is to understand the molecular 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 maturation and of cognitive and emotional behaviors. Our work also extends to translational studies that investigate how altered inflammatory cascades are involved in other psychiatric conditions, such as delirium. We hope our research ultimately identifies new therapeutic targets for early intervention of these devastating conditions.
