The Social and Behavioral Development Lab investigates genetic and environmental factors that contribute to individual differences in the development of child ADHD and other externalizing disorders (i.e., oppositional defiant disorder and conduct disorder). Research in our lab combines advanced molecular genetic approaches (e.g., genome-wide association studies, polygenic risk scores, gene-pathways analyses) with rigorous measurements of environmental influences to uncover psychosocial mechanisms of psychiatric outcomes and predict psychiatric outcomes. The goal of this research is to better understand how individual differences in child behavioral development and the development of psychiatric outcomes arise as a function of our DNA and our environments, and to ultimately create more effective and personalized mental health care.
