Martijn de Vries is a PhD candidate of the Department of Engineering Systems and Services. He holds a Master's degree in Philosophy and in Environment and Resource Management. His previous research focussed on the philosophical and empirical issues related to measuring human wellbeing. 

My current research focusses on identifying barriers for the operationalisation of the 'wellbeing economy' ('brede welvaart' in Dutch) in public policy evaluation. I also explore how these barriers can be overcome through participatory policymaking practices. To this end, I study participatory evaluation methods, with a particular interest in Participatory Value Evaluation (PVE).
