My research aims to 1) understand the development of externalizing behavior problems among diverse children and adolescents who are at-risk for experiencing adversity and victimization, and 2) identify the evidence-based intervention and prevention strategies that promote positive adaptation among these youth. I use advanced quantitative methods to identify the risk and protective processes through which violence, abuse, neglect, and other adverse and traumatic events contribute to maladaptive academic, social, behavioral, and occupational outcomes among children and adolescents from at-risk and ethnic minority populations. Building on these findings, I conduct research on the development, adaptation, refinement, and evaluation of evidence-based psychosocial intervention strategies to promote physical, academic, social, and emotional well-being among diverse children and adolescents, as well as their families.
