- director of the Paul Scholten Centre for Jurisprudence;
- member of the Vaccinations Committee of The Health Council of the Netherlands; and
- Dean for PhD students (Promovendi-decaan) of the University of Amsterdam Law School.
My research interests concern the intersections of legal philosophy, political theory, law and public policy, with a special interest in contemporary liberal theories of justice and their application in plural societies and the globalising world. My recent work focuses on human rights, the rule of law, religious diversity, and cosmopolitanism.
In 2015 and 2016 I was affiliated as a "visiting fellow" to Ripple (Research in Political Philosophy in Leuven) at the Faculty of Philosophy, University of Leuven. Before that, I was a visiting scholar at the Centre for the Study of Social Justice of Oxford University (2013), University College London (2005), Columbia University (2004) and Ottawa University (1997-1998).
Before I came to Amsterdam, I taught political theory at Radboud University Nijmegen and legal theory at Tilburg University.
