Research Interests

  • Normal adolescent development and rule-breaking behavior
  • Behavioral genetics
  • Individual differences in social attitudes and pubertal growth

My research focuses on the relationship between normal adolescent development and rule-breaking behavior. To this end, I examine how individual differences in social attitudes and pubertal growth translate into risk for aggressive/delinquent behaviors. I view the adolescent increase in sensation-seeking and social nonconformity as a kind of double-edged sword, as it promotes the emerging adult’s independence but also contributes to substance abuse and other negative outcomes. I am a behavioral geneticist by training, and seek to understand the genetic and environmental bases of these associations
