My research focuses on early identification and intervention in schizophrenia. This includes identifying risk factors for developing psychosis, diagnosing prodromal psychosis, and testing novel interventions for early psychosis. In addition, I have developed evidence-based treatment programs for early psychosis through community-academic partnerships.
