After graduating in Work and Organizational Psychology at the Radboud University in Nijmegen and obtaining my PhD at Eindhoven University of Technology, I now work as an assistant professor in Work & Organizational Psychology at the Erasmus University Rotterdam. In my research, I am driven by a fascination with the functioning of groups and teams. The overarching theme of my research is regulatory processes in groups and teams. I study how teams shape and coordinate their collective activities to achieve effective performance while safeguarding the well-being of the individual team members. Specific topics within this theme include motivation (goal setting and goal orientation), team autonomy and self-management, conflict and conflict-management, and methodological issues involved in measuring group-level constructs.
