Welcome

Welcome to the Developmental Behavior Genetics Lab.

We study psychopathology during adolescence, particularly the emergence of externalizing behaviors like substance use, delinquency, and risky sexual behavior.  We are currently focusing on two research streams.  First, how do individual differences in “normal” developmental processes, such as puberty, contribute to “abnormal” behavior?  Second, how do genetic risks interact with family and social environments to produce psychopathology (gene-environment interaction)?

Our research uses a variety of behavioral genetic methodologies, including twin and children-of-twins designs. In addition to analyzing behavioral genetic data from the National Longitudinal Study of Adolescent Health and the Australian Twin Registry, we are starting a new twin registry in central Texas: The Twin Project at the University of Texas. The Twin Project is conducted in collaboration with the Tucker-Drob Lab at the University of Texas and the Tackett Lab at Northwestern University. We also regularly collaborate with the Mendle Lab at Cornell University.

In addition to research, I also currently teach an Introduction to Psychology SMOC (synchronous massive online course) and a seminar on adolescent development.
