Hui Zheng is a professor of sociology at The Ohio State University. His research focuses on the dynamics of population health and aging, and encompasses two interconnected areas: social and policy determinants of health; and population process of aging and mortality. He has investigated health consequences of various social structures, institutions, and policies; the trends of socioeconomic and demographic disparities in health; trend and heterogeneity in aging, mortality, and life span; the impact of life course dynamics of obesity on mortality; and the role of selection in health production and aging process. His current projects investigate the rising health challenges in the U.S.; cohort and life course dynamics of cognitive aging; and nativity disparities in labor market and health. His work is supported by CDC (National Center for Health Statistics) and NIH (NIA, NICHD).
