I am an associate professor at the Department of Human Resource Studies, Tilburg University, Netherlands and a professor at the Center of Excellence for Positive Organizational Psychology, at Erasmus University Rotterdam. The well-being and development of workers are central themes in my research. Inspired by positive psychology. I am intrigued by the question what happens if we take individual strengths instead of deficits or weaknesses as the starting point for developmental processes. I am member of the editorial board of Human Resource Development Review, Human Resource Development International and the Dutch journal for Positive Psychology. Currently. I am leading a three-year project on stimulating the professional development of VET teachers by a strengths-based approach, funded by The Netherlands Initiative for Education Research (NRO). I publish my research in journals like Journal of Applied Psychology, and European Journal of Work and Organizational Psychology.
