My research focuses on the health of populations, and encompasses three interconnected areas: social and policy determinants of health and dynamics of health disparities; population heterogeneity and dynamics of obesity, aging and mortality; and medical expansion and population health.
In the first area, I investigate the impacts of macro, meso, and micro social and policy factors on health, and how these factors interact and shape trends in health disparities. For example, I have investigated the health consequences of income inequality; marital differences in health reporting and mortality; the role of selection vs. causation in the health process; and the health consequences of the one-child policy and unbalanced sex ratio at maturity. I developed and applied statistical and demographic methods to investigate the interplay of social changes, epidemiological transition, life course, cohort replacement, and population dynamics on the trends in health / mortality disparities. In the second area, I have investigated heterogeneity in the life course of obesity and its effect on mortality; cohort forces in the origins and pathways of health and mortality over life course; population heterogeneity and temporal trends (age, period, cohort) in mortality and life span; and the role of cohort evolution and mortality selection in the trend of demographic and biological aging. In the third area, I have investigated the process of medical expansion and its impact on population health, perception of health, and confidence in medicine.
My ongoing work addresses (1) the effect of selection bias and unobserved heterogeneity in the process of health production, the trends of aging, obesity, health disparities and life expectancy; (2) the role of cohort forces in life course of health and mortality pattern; (3) labor market, workplace, and jobs, and their health and mortality implications in the developed countries; and (4) mixed race, skin tone, and health.
