Welcome
— I’m Thomas Verellen
I’m an Assistant Professor of EU and International Law at Utrecht University, where my research explores how geopolitical shifts are reshaping the EU’s trade and investment policy. I focus on the intersection of EU law, foreign relations, and global economic governance, with particular interest in the legal and institutional implications of the EU’s increasingly assertive external economic actions.
My recent work examines the EU’s ‘unilateral turn’ in trade and investment policy and the challenges this poses for legitimacy, accountability, and the rule of law. I coordinate and teach a range of EU law courses and co-lead the “EU Values in International Trade” research theme at the Utrecht Centre for Regulation and Enforcement in Europe (RENFORCE). I also serve as Managing Editor of the Utrecht Law Review.
I hold a PhD in law from KU Leuven, where I defended my dissertation on EU foreign relations federalism in 2019. A revised version was published by Oxford University Press in 2023. I’ve held visiting positions at KU Leuven, the University of Michigan Law School, and the Université de Montréal, and previously trained at the Court of Justice of the European Union.
Alongside my academic work, I maintain a legal practice. I am a member of the Belgian bar and advise clients on EU trade law and migration law. I previously practiced at international law firms in Brussels, focusing on trade defence instruments. Today, I combine academic insight with practical experience to offer legal services that are both rigorous and responsive.
