Hi,
My name is Thomas Verellen. I research, teach, and advise on how geopolitical shifts are reshaping the EU’s trade and investment policy.
I am a tenured Assistant Professor of EU and International Law at Utrecht University, where 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. Starting in 2026, I will co-teach a module on EU trade law at the Université libre de Bruxelles (ULB).
My research examines how the European Union responds to geopolitical and systemic challenges through its trade and investment policy, with a particular focus on the legal and institutional mechanisms that underpin the EU’s external economic governance. I draw on constitutional theory to explore how values such as the rule of law, democratic control, and accountability shape and constrain the EU’s use of unilateral trade instruments. My work also engages with insights from international political economy to situate these developments within broader shifts in global economic order and regulatory power. Through this interdisciplinary lens, I aim to contribute to academic and policy debates on the EU’s evolving role as a global actor and the constitutional implications of its external action.
Alongside my academic work, I maintain a legal advisory practice in EU law, with a focus on EU trade law issues. I advise companies and public institutions on complex regulatory and strategic questions, with a particular emphasis on the EU’s new unilateral trade instruments — including the Carbon Border Adjustment Mechanism (CBAM), the Foreign Subsidies Regulation, and trade defence measures. I also dedicate part of my time to pro bono work on human rights issues, including migration, supporting individuals and organizations in need of legal assistance.
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 also hold an MSc in Global Politics from the London School of Economics. 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.
