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 immune processes (e.g., accelerated immune aging, latent viruses, inflammation) at different time scales; (b) The moderating role of individual and interpersonal emotion regulation in stress-immune health associations; and (c) Dynamic emotion and biologic responses to stress, particularly in terms of recovery, that may explain health outcomes. 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.
