In my research, I focus on (1) how aging, social change, and population processes interact with social institutions such as schools and family to produce inequality and disparities and (b) identifying trajectories and explaining trends in health, cognitive, and mortality outcomes.  I have developed a novel model for determining age, time periods, and cohort patterns in various outcomes such as cognitive development, health status and behaviors, mortality, and substance use.  I also study quantitative methods for describing and explaining temporal trends in health behaviors and vital rates.  I recently expand my research areas to investigating the heterogeneous effects of education between men and women on their health and social well-being.  My work has appeared in prestigious journals including American Journal of SociologyDemography (lead article with four commentaries and a reply), Sociological Methods & Research and Sociological Methodology.  I serve on the editorial board of Sociological Methods & Researchand Sociological Methodology.
