My programmatic research focuses on high-risk health behavior (with a focus on alcohol use/misuse) as a developmental phenomenon that is shaped by the interplay between person and environment over time. In the dynamic interactionism perspective, individuals develop through the ongoing reciprocal interplay with their social environment. Applying interactionism to alcohol use/misuse, my research seeks to characterize mechanisms by which individual factors and environmental factors influence each other and determine the course of alcohol use/misuse across the lifespan. The ultimate goal of my research program is to promote a greater understanding of these risk pathways in order to inform the development of targeted prevention strategies that reduce problematic alcohol use among high-risk populations.
