The purpose of my research is to explore and simulate the impact of interventions aimed at reducing exposure to the food retail environment, with a focus on decreasing the consumption of foods and beverages high in fat, salt, or sugar (HFSS food). The goals of the research are to understand how an individual's interaction with the food retail system produces unequal patterns of health in the population by using agent-based models and to explore how food purchasing behavior changes with the implementation of policies that encourage a healthier food retail environment.
