We are Tilburg University


My academic education took place at the University of Amsterdam, where I obtained a Master degree in Behavioral Economics and Game Theory as well as a Research Master degree in Psychology. During my studies I realized that the social sciences are not functioning as well as they should and that there are issues at both the institutional level and at the level of individual researchers. In my PhD-project, I mainly focus on the latter by studying researchers' ideas about nonsignificant results, meta-analytic results, and the complexities of preregistration. Other research interests of mine include evolutionary psychology, human cooperation, and network analysis.


In the academic year 2017/2018, I am responsible for the tutorials of the courses 'Techniques of Causal Analysis', and 'Construction and Analysis of Questionnaires'.
