My research program examines how social contextual factors influence health risk behaviors, with primary emphasis on etiology and prevention of alcohol and other substance use. I approach my research from a social psychological orientation that emphasizes how social cognitions (both heuristic and reasoned) mediate the relation between contextual factors (e.g., peers, family, and neighborhood) and health risk and promotion behaviors. Recently, much of my work has focused on expanding efficacious prevention programs to prevent high-risk drinking among vulnerable populations, including African American youth and emerging adults who do not attend traditional four-year universities. A common theme throughout much of my research is the appropriate application of advanced quantitative methods, including latent variable and finite mixture modeling techniques.
