The Society, Health, and Racial Equity (SHARE) Lab serves as a forum for research on health and social equity, and the role of racism in generating and perpetuating injustices in health. As part of this work, we examine multiple ecological levels of influence on health—ranging from broader social forces to the cellular level—using a developmental lens. We examine their interplay in relation to health inequities, which are conceptualized as unjust patterns in the population-level distribution of disease that are avoidable and preventable. Our research addresses underlying social inequities that give rise to poor health outcomes in communities that have been discriminated against, marginalized, and excluded.
