Research Areas:

Clinical Psychology | Social & Personality | Developmental Science

Research Summary:

My research examines the contribution of individual differences to deviance across the lifespan. Within this general area I am developing two related programs of research. The first program uses a developmental psychopathology approach to understand the role of personality in the etiology of externalizing disorders (psychopathy, antisocial personality disorder, narcissism, and disorders of conduct and impulse control). In the second program of research, I construe unhealthy and deviant behaviors (substance use, risky sex, gambling, aggression, crime, etc.) as natural outcomes in the absence of specific internal controls, such as constraint and empathy.
