Research summary

Valerie S. Knopik studies how genetics, prenatal exposures (such as maternal smoking and cannabis use during pregnancy), and family/peer environments jointly shape child and adolescent development, including behavioral problems, substance use, and mental health outcomes. Her work often uses twin and adoption study designs to disentangle genetic from environmental influences on these outcomes across development. This research is intended for students interested in developmental psychopathology, behavioral genetics, and the effects of prenatal substance exposure.
