Institute for Behavioral Genetics
University of Colorado Boulder
447 UCB
Boulder, CO 80309-0447
Research Interests:
The use of cross-sectional and longitudinal studies of twins and families to study behavioral development, and genetic and environmental influences on behavior, personality, and health. Recent research focus on the development of behavior problems in childhood and adolescence, vulnerability to drug use, abuse, and dependence, genetics and health, and linkage and association studies of behavioral traits. Dr. Hewitt is the Editor-in-Chief of the journal, Behavior Genetics. He was Director of the Institute for Behavioral Genetics from 2001-2022.
