My primary research program focuses on the joint effects of genetic, epigenetic, and environmental (specifically prenatal and early postnatal) risk factors on birth outcomes, externalizing behavior (e.g., ADHD), associated learning and cognitive deficits, and subsequent substance use.

I also collaborate with local, national, and international scientists on projects including, but not limited to: cannabis-related outcomes, sleep, adolescent alcohol use disorder, family interventions for adolescent substance use, depression-related outcomes, epigenetics, and child maltreatment. My research is inherently collaborative and interdisciplinary, integrating across research traditions and study designs, incorporating community as well as high-risk genetically-informed samples.

I am Associate Editor for Behavior Genetics, on the editorial board of Psychological Medicine, and a consulting editor for Child Development, as well as the lead author on the textbook, Behavioral Genetics (7th ed).
