Research

research overview

  • Areas of current interest are: behavior genetics of drug use, abuse, and dependence in adolescents and adults, including the impact of marijuana legalization; behavior genetic analyses of cognitive executive functions; contributions of genetics and effects of drug use on the development of brain and behavior in adolescence. Methods include the study of twins, adoptees, and nuclear families, and genome wide association studies (GWAS). We are collaborating on brain imaging studies of structure and function. Our research requires interdisciplinary collaboration across psychology, molecular biology, neuroimaging, and statistical genetics, paired with expertise in the phenotypes. We are a research site for the national Adolescent Brain and Cognitive Development (ABCD) initiative
