Vassilis Hatzopoulos is a full Professor of EU Law and Policies at the Panteion University, Athens. Previously he was a professor at the Democritus University of Thrace, where he also served as Chair of his Department, then Dean of his School. He is a visiting Professor at the College of Europe, Bruges (Belgium).

His research interests cover EU institutional law and governance, the EU internal market with special focus on service liberalisation and the provision of services of general economic interest, state aid and public procurement, as well as EU asylum and immigration law. He has published five monographs, on the principle of mutual recognition in the internal market (in French, Bruylant/Sakkoulas, 1999), on domain names (in Greek, Nomiki Vivliothiki, 2001, with V, Tountopoulos), on the doctrine of essential facilities under EU competition law (in Greek, Sakkoulas, 2002), on the regulation of services in the EU (in English, OUP, 2012) and on the collaborative economy and EU law (in English, Hart, 2018). He has also published over a hundred articles and case notes, in English, French and Greek, in all the major EU-related reviews and periodicals and in edited volumes. His long-standing interest on services translates into dozens of articles as well as several consultations, both institutional and private, in this area.

He has a longstanding experience as a lawyer, practicing before the highest national courts and the Court of Justice of the EU. He has consulted i.a. the Greek Government (on the OECD-led regulatory reform and the Lisbon Strategy benchmarking), the EU Commission (on the Services Directive) and the European Parliament (on EU patients’ rights). Lately his research interests turn around the sharing economy and the EU preferential trade agreements (CETA, TiSA etc).

Dr. Enguerrand Marique is currently an associate professor at the Université catholique de Lille (FR) and guest lecturer at UCLouvain (BE). He teaches business law and new technology law. After completing a master’s degree in law at UCLouvain and an additional master’s degree in international commercial law in California, in 2021 Dr. Enguerrand Marique defended a thesis on digital platform law entitled “Building Trust in Digital Platforms via legal tools: new roles and new responsabilities for public authorities and private entities”.

From 2020 to 2025, dr. Enguerrand Marique was universitair docent at Radboud University (NL), where he taught digital single market law and dispute resolution in a digital environment.

His research focuses mostly on the regulation of digital technologies, particularly in cases where their civil applications adversely affect citizens’ or consumers’ trust (in the technology deployer). He is interested in how governance mechanisms can be innovatively designed to rebuild and sustain this trust, especially in environments where transparency and accountability are at stake (data, platforms and AI). This includes examining the role of EU regulatory frameworks in mitigating the erosion of trust and ensuring that digital technologies are deployed in ways that respect ethical principles and reinforce public confidence.

Another strand of his research focuses on digital sovereignty and the critical role public authorities play in fostering a distinctly European digital ecosystem. He explores how regulatory and policy measures can strengthen Europe’s autonomy in the digital realm while balancing innovation, competition, and ethical considerations. This includes examining the interplay between digital sovereignty and global digital governance, highlighting how European public authorities can shape frameworks that safeguard European values and promote trust in a connected world.
