Manfred Diehl is a University Distinguished Professor in the Department of Human Development and Family Studies. His research addresses how successful and healthy adult development and aging can be promoted by changing people’s negative views of aging, and by educating them about healthy lifestyle changes. In addition, Diehl studies how certain self-regulatory behaviors like coping strategies and emotion regulation across the adult lifespan develop and change, and how adults develop an awareness of their own age-related changes.
