Hui Zheng (Ph.D., Duke University, 2011) is Assistant Professor of Sociology at Ohio State University. His major scholarship applies advanced statistical and demographic methods and interdisciplinary perspectives to study the causes and consequences of health, aging, and mortality. His current research focuses on four areas: the interplay of historical changes, life course and population dynamics on the trends in health disparities; individual trajectories, aggregate trends and population heterogeneity in obesity, aging, vitality and mortality; the interplay of social institution/structure and biological factors on health; and the implication of medicalization on population health. Besides his work in health and aging, he is also interested in studying the causes of crime and consequences of punishment. He is currently investigating the effect of excecutions on homicides and how this effect may be differed by the types of homicides by using dynamic regression - linear transfer function models.
