Research Focus

Our laboratory aims to understand the neural basis of social and prosocial behavior. Furthermore, we seek to uncover the mechanisms behind social dysfunction in neuropsychiatric disorders like autism spectrum disorder, depression, and antisocial personality disorder, with the goal of informing new intervention strategies.
