Mirjam is currently a postdoctoral researcher at the Lifespan lab. She received her PhD at the University of Zurich in Switzerland (Department of Psychology and at the URPP ‘Dynamics of Healthy Aging’). During her PhD, Mirjam’s research focused on the development and investigation of digital interventions that target personality change. The goal of these interventions was to coach individuals who are willing and motivated to change some aspects of their personality. As part of her PhD, Mirjam developed the psychological part of the smartphone application ‘PEACH’ in collaboration with the ETH Zurich, University of St. Gallen, and Dartmouth College, which delivers a digital personality change coaching intervention.
Overall, Mirjam’s research interests lie at the intersection between personality psychology, (digital) intervention approaches, behavior change, and healthy aging. Her major interest focuses on how to help individuals effectively to improve their well-being and physical health in the long run and to identify (risk-) factors and mechanisms to personalize interventions in order to inform interventions.
