Laura Kubzansky is professor of social and behavioral sciences and director of the Society and Health Laboratory at Harvard T.H. Chan School of Public Health. She has published extensively on the role of psychological and social factors in health, with a particular focus on the effects of stress and emotion on heart disease. Kubzansky conducts research on whether stress, emotion and other psychological factors help to explain the relationship between social status and health. Other research interests include the biological mechanisms linking emotions, social relationships, and health, the relationships between early childhood environments, resilience, and healthy aging, and how interactions between psychosocial stress and environmental exposures (e.g., lead, air pollution) may influence health. She is co-PI of the Work and Well-Being Initiative.
