Hui Zheng is a demographer, social epidemiologist, and quantitative social scientist. His research examines the causes, trends, heterogeneity, and inequalities of population health and aging, developing statistical and demographic methods to evaluate how social, epidemiological, and biological processes shape health and mortality. He has studied how social structures and institutions (e.g., income inequality, medical expansion, work environments, and the marriage market) affect health outcomes; trends in health disparities; heterogeneity in aging and mortality; the life course effects of obesity; and the role of selection in health production and aging. His current projects address rising health challenges in the United States and nativity disparities in labor market outcomes, aging, and health.
