Dr Napoleon Xanthoulis


Napoleon Xanthoulis is Senior Lecturer in Law at Portsmouth Law School. His research interests extend to the fields of Constitutional and Administrative Law, with emphasis on EU law and the law of the law of the Economic & Monetary Union as well as the intersection between law & digital technologies.

Napoleon is currently a principal investigator of the project ‘UK-Ireland Cross-border Data Protection Network’, co-funded by the UKRI/IRC (2020).

An important stream of Napoleon’s research aims to create a conceptual framework for the notion of ‘legal effects’ in EU law. It builds on his doctoral thesis at King’s College London which examined the legal effects and justiciability of EU acts with focus on the conduct of the European Central Bank. In 2017, he was awarded a project by the European Central Bank to explore the legal significance of public announcements in central banking. His article tracing the legal effects of EU factual conduct was awarded the Faculty Research and Dissemination ECR prize in 2020. Recently, Napoleon was invited to contribute to the project ‘Academic Network of Soft Law Research (SoLaR)’, funded by the European Commission.

A significant part of Napoleon’s research focuses on the law and governance of the Economic and Monetary Union exploring aspects of legal effects, judicial protection and institutional balance. Part of his work traces the role of the European Central Bank during the euro crisis and in the post-crisis era with emphasis on its monetary policy mandate and liquidity provision. The regulation and governance of the European Banking Union and financial assistance also fall within the scope of his research. 

Napoleon’s work also engages with the emergence of a new rule of law culture within the EU and explores its normative challenges. In 2021, he is co-organising a conference on the Rule of Law in the EU in collaboration with the European University Institute and KCL Centre of European Law. Furthermore, he has been invited to contribute to a European Law Institute project that aims to conceptualise the rule of law in the modern era.


At the University of Portsmouth, Napoleon is appointed Assistant to Research Lead at the Law School (2019-) and responsible for the School's Research Seminars Series (2019-). He also founded the School's first online Law Blog and leads the editorial team (2020-). In 2019, he was elected ECR Lead at the Faculty of Business & Law. He is also Fellow at the Centre of European Law, King’s College London.

Between 2016-2019 he was Visiting Lecturer in EU Law at King's College London. Moreover, he was a visiting researcher at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg (summer 2018).

Napoleon was awarded his PhD at King's College London with a full studentship from the KCL Centre of European Law, having obtained an LLB (Hons) at University College London. Before embarking into the realm of the law, he undertook undergraduate and Masters studies in political science (National and European Governance) at Panteion University of Social and Political Sciences in Athens. He practiced law at one of the largest law firms in Cyprus and acquired work experience at the European Commission and several law firms in Brussels and Athens.
