Research Interests

My research develops in the following main streams:

Law & digital technologies: I research on the impact of digital technology on data protection, fundamental rights and the rule of law. In 2020, I applied for a ESRC/IRC grant with a project aiming to build a UK-Irish Cross-Border Data Protection research network. Furthermore, I received internal funding (Research Project Fund) to explore the legal implications of online political disinformation.

Legal effects & judicial review in EU law: An important stream of my research aims to create a conceptual framework for the notion of ‘legal effects’ in EU law. It builds on my doctoral thesis at King’s College London which examined the legal effects and justiciability of Union acts with focus on the conduct of ECB. In 2017, I was awarded a project by the European Central Bank (Legal Research Programme) to explore the legal significance of public announcements in central banking. An article of mine tracing the legal effects of EU factual conduct was awarded the Faculty Research and Dissemination ECR prize in 2020. Recently, I was invited to contribute to the project ‘Academic Network of Soft Law Research (SoLaR)’, funded by the European Commission. In this context, I carried out an empirical research on the impact of EU soft law on Cyprus in the fields of competition law and financial regulation. In a separate piece, I analysed to what extent intentions and perceptions about legal effects can  influence judicial reasoning on whether an act can be subject to judicial review in EU Law.

Law & Governance of the Economic & Monetary Union: A significant part of my 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 my 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 my research. 

Rule of Law in the EU: My work also engages with the emergence of a new rule of law culture within the EU and explores its normative challenges. In 2021, I will be 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, as part of a project that received internal faculty funding.  Furthermore, I have been invited to contribute to a European Law Institute project that aims to conceptualise the rule of law in the modern era.


At Portsmouth, I am appointed as Assistant to Research Lead at the Law School (2019-) and responsible for the School's Research Seminars Series (2019-). I also founded the School's first online Law Blog and lead the editorial team (2020-). In 2019, I was elected ECR Lead at the Faculy of Business & Law. I am Fellow at the KCL Centre of European Law.

I was awarded my 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, I undertook undergraduate and Masters studies in political science (National and European Governance) at Panteion University of Social and Political Sciences in Athens. I have 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. Between 2016-2019 I was Visiting Lecturer in EU Law at King's College London. Moreover, I was a visiting researcher at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg (summer 2018).
