My research focuses on health heterogeneity, including methodological inquiries that bring to light the variability masked by aggregate population health statistics and applied research that explores links between social stratification and health disparities. My work draws on theories from formal demography and social gerontology and employs innovative mathematical and statistical methods to characterize the changing profile of health and wellness in aging societies. Integrating a life course perspective into analyses of population dynamics, my research agenda links individual health patterns with aggregate demographic trends within three lines of inquiry: (1) the formal demography of longevity, (2) health and inequality across the life course, and (3) global aging, migration, and health.
