TAMAR DE WAAL is Assistant Professor at Amsterdam Law School (University of Amsterdam). In 2017 she defended her disser-tation Conditional Belonging on the proliferation of integration re-quirements in EU Member States, for which she received the VWR-dissertation prize for best disser-tation in legal philosophy in the Netherlands. It examines the rela-tionship between the proclaimed commitment of Member States states to the core liberal-demo-cratic values of the EU and their actual integration laws and prac-tices. During her visit at MPI she will be revising her dissertation for publication as a monograph at Hart Publishing.
