I studied psychology, economics, and biology at Amsterdam University College (BA Social Sciences, 2013) and methodology and statistics and organisational psychology at the University of Amsterdam (MSc Psychology, 2016), with short stints at Harvard (2011) and McGill (2012). Before that, I worked as a journalist in Berlin. From 2014 to 2016, I was core tutor at PPLE College, University of Amsterdam.

Curriculum Vitae

PhD project

I joined the Amsterdam Cooperation Lab in 2016 to work with Daniel Balliet on interdependence and cooperation. My research is centered around people’s experience of interdependence: I seek to (a) map the patterns of interdependence people experience in daily life, (b) probe the mechanisms by which people infer outcome interdependence from cues in their social environment, and (c) test how this subjectively experienced interdependence shapes cooperative behavior.

Research interests

I am interested in personality-situation interactions and transactions in prosocial behaviour: How personality shapes and interacts with situation characteristics to produce prosocial behaviour. In my studies, I use a variety of methods ncluding economic games, experience sampling, and meta-analysis. Finally, I am a strong proponent of open science and interested in projects that further replication, pre-registration, and better theorising in the behavioural sciences. In this spirit, I also serve as the Center for Open Science representative for the department.
