I am Director of the Prevention Research Center, located in Oakland, CA. I have a strong research background in alcohol, tobacco, and drug use among children, adolescents, and young adults. My studies have included both basic research and large-scale community prevention trials. I was a member of the Institute of Medicine/National Research Council Committee on Developing a Strategy to Reduce and Prevent Underage Drinking for the National Academies of Science. My research broadly focuses on social-psychological and environmental factors influencing drinking and other problem behaviors among adolescents and young adults. My research has included studies on media, peer, family, and community factors related to sexual risk-taking, drinking, smoking, and marijuana and other drug use. I have over 145 publications. I was PI on a large NIAAA-funded randomized community trial to prevent alcohol use and problems among adolescents in 36 Oregon communities. My current research projects include longitudinal survey studies on the relationships of local policies and community, school, and family factors with drinking and smoking trajectories among youth in 50 mid-sized California cities. I am PI on a NIDA-funded randomized community trial investigating the effects of family, school, and retailer interventions on access to and use of inhalants and other harmful legal products by adolescents in frontier Alaska communities. I have a strong background in survey research methods and quantitative data analysis, including latent variable structural equation modeling, latent growth modeling, and related techniques.
