Guillaume GRÉGOIRE holds a PhD in legal science and is a researcher in the department of Economic Law and Theory of Law in the Faculty of Law, Political Science and Criminology of the University of Liège. At the intersection of public economic law, legal history and legal theory, his research focuses on the phenomenon of constitutionalisation of the economy, using both a comparative method (study of the Belgian, French, German and European legal systems) and a contextual approach (study of the theoretical and historical influences behind the phenomenon).

He obtained a double master degree of law at University of Liège in 2015 and of management at HEC Management School - University of Liège in 2016. He has been appointed as Research Fellow of the Belgian Fund for Scientific Research (2017-2021) and was invited as a visiting researcher in the Centre de droit européen (CDE) of the University Paris-Panthéon-Assas (September-December 2018) and in the Max-Planck-Institut für Innovation und Wettbewerb in Munich (January-July 2019).

He is the author of L'économie de Karlsruhe. L'intégration européenne à l'épreuve du juge constitutionnel allemand (CRISP, 2021: ) and the co-editor of The Idea of Economic Constitution in Europe. Genealogy and Overview (Brill, 2022, available in Open Access at:
