All planned and published publications


Research expertise lies in the field of EU law and international law, with a focus on questions of institutions and governance. A particular focus is on the interface between EU and international law and the external effects of internal EU policies. Key research areas include EU institutional law and external relations, EU foreign, security and defence policy, trade policy, regulation of cybersecurity, international organziations and the vertical relations between legal orders (global-EU-domestic). All of this is approached from the perspective of new developments in EU and global governance and multilevel regulation with a focus on changes in the relationships between citizens and their government at various levels. Research activities are furthermore embedded in the Netherlands Institute of Government (NIG) and connections exist with the EU and international law programs of the Ius Commune Research School.
