My research focuses on biopsychosocial factors that contribute to health across the later adult lifespan. I investigate three inter-related areas: (a) The effects of stress on biological aging (e.g., accelerated immune aging, inflammation, latent viruses, epigenetic aging) at different time scales; (b) Protective factors including emotion regulation and social relationships that buffer associations between stress and accelerated aging; and (c) Biopsychosocial factors that affect cognitive function and decline in middle-aged and older adults. I incorporate measures in the laboratory and in daily life settings to examine these processes over time, and use multilevel statistical models to analyze longitudinal and interdependent data.
