CV (up to date, January 2015)


My main research interest lies in the development of theory to explain, predict and influence health behavior. Specifically, I study the dynamic interaction of health and other personal goals, including the role of intergoal facilitation and - conflict. Moreover, I explore intervention techniques to strengthen the link between a health goal and other personal goals, e.g. by connecting the health goal to future "possible" selves, or by boosting “transitional identities”, and/or by applying techniques to reduce goal conflict and ambivalence. In addition, I work on the evaluation of the effects of (governmental) interventions to encourage healthier lifestyles, and on the improvement of the process of intervention implementation.
