Our lab focuses on understanding externalizing psychopathology in childhood and adolescence, including physical and relational aggression, delinquency, personality disorder, and addiction. We adopt a multiple levels of analysis approach, incorporating genetic and hormonal biomarkers of externalizing problems and also examining the impact of environmental factors such as parenting, friendships, life stress, and SES on externalizing problems and potential gender and racial/ethnic disparities. Another major research program in the lab focuses on measurement and development of child and adolescent personality, broadly conceived, but with special attention to the development of social dominance and self-control.
