Summary of research:
As a life-span researcher taking a developmental psychopathology perspective, I conduct research on the influences of family and peer processes that shape different developmental trajectories of problem behaviors using innovative quantitative methodology at multiple levels of analysis (e.g., genetic, behavioral) and time scales (e.g., days, years) in various ecological contexts (e.g., school, neighborhood, culture). In addition, a major goal of my research agenda is to evaluate intervention programs that aim to prevent these problem behaviors, especially among at-risk populations. My research focuses on four interrelated themes: 1) family and peer processes that shape different developmental trajectories of problem behavior using mixture modeling; 2) genetic and environmental interplay in the development of problem behavior using quantitative genetic modeling; 3) intra-individual developmental processes at a micro level using intensive longitudinal data with time series analysis; and 4) evaluation of preventative interventions using dynamic al system analysis and longitudinal growth curve modeling.
