Research Interests

My research focuses on enhancing early identification of psychosis. I am particularly interested in understanding social behavior and social cognition in the prodromal period of psychosis. My research uses various neuroimaging modalities to investigate neural underpinnings of social processes as a means of understanding severe mental illness.
