    Research Areas
    • Developmental course, assessment, prevention, and treatment of conduct problems in youth. 
    • Family based interventions for the treatment of conduct problems in young oppositional children.
    Summary

    My research focuses on understanding how conduct problems develop in children and adolescents, their developmental course over time, and how best to prevent and treat these problems, especially in the context of the family.

    Current Projects
    Current research projects include: 
    • Development of a new family based intervention that combines parent management training with emotion coaching for young children diagnosed with oppositional defiant disorder and who exhibit low prosocial emotions
    • Evaluation of the effects of Fast Track, a long-term, comprehensive intervention designed to prevent serious conduct problems in high-risk children. 
    • Emergence of adolescent substance use problems from the externalizing spectrum. 
    • Developmental pathways of conduct problems. 
    • Two RCTs of Connect, an attachment–based parenting intervention for the prevention and treatment of serious conduct problems in adolescent youth (age 10-16) (with Marlene Moretti).
