We use behavioral genetic research methods to understand the developmental roots of social inequality, with a particular focus on the second decade of life.

Our work considers multiple aspects of early development — how well young people do in school, when they experience pubertal maturation and parenthood, when and how heavily they drink or use drugs, and whether they engage in other behavioral risks that imperil themselves or other people. Together, these experiences shape people’s physical health, mental health, and economic opportunities for the rest of their lives.
