Principal Research Interests

My main field of research is health and safety risk-taking behaviors. We know that emerging adults (ages 18-25), particularly emerging adults enrolled in 4-year colleges, participate in the highest rates of risky behaviors associated with unintentional injury and death.

My research focuses on understanding developmental changes and individual differences that contribute to this increase in risk-taking behaviors, with particular emphasis on social and cognitive factors. In another line of research using a social-cognitive framework, I have looked at bullying and victimization behaviors among older children and adolescents.

Research Areas: 

  • Health and safety risk-taking behaviors
  • Decision-making
  • Emerging adulthood
  • Bullying
  • Peer relations
