Professorship for Differential Healthy Aging Research

Prof. Dr. Mathias Allemand


This professorship examines individual differences in healthy aging and investigates longitudinal associations between personality, daily activities, psychological health and well-being of middle-aged and older adults. Basic research of the professorship focuses on long-term personality development across adulthood into old age and on short-term dynamic processes to maintain or to improve health and well-being in daily life contexts as well as in laboratory settings. Applied research of the professorship focuses on the development and evaluation of evidence-based health-related interventions and consulting approaches.

The professorship is part of the University Research Priority Program Dynamics of Healthy Aging (more) and the Department of Psychology.
