Professor Konstantinos Stylianou

  • Professor in Competition Law (School of Law)

Biography

I am a Professor of Competition Law and Regulation – I joined the School in early 2023 from the University of Leeds.

My research and teaching focus on digital markets, blockchain, and high-tech industries in general. I am interested in the nature and function of competition, the choice between competition and regulation, and how markets are organised around new technologies.

I enjoy translating my research into policy and government work and I have been fortunate to have had various opportunities through the years. In 2020, I was appointed to the Lawmaking Commission convened by the Greek government on the modernisation of competition law in Greece, and more recently, I was appointed to the Weihai Arbitration Commission assigned on cases in competition law, I advised the Saudi Arabia government on competitiveness in the domestic fintech market, and I also served as a Special Scientific Advisor to the Hellenic Competition Commission. Through the years, I have also worked with various tech companies including Google and Meta (Facebook), and I have delivered training to judges and government officials in the frame of programmes run by the EU, OECD, and the governments of Thailand, Saudi Arabia, and Greece. I also sit on the advisory/editorial boards of various organisations/journals (see below).

Much of my work is collaborative. Between 2019 and 2023 I was part of the team from Erasmus, Leeds, and Bar-Ilan that won a Jean Monnet Centre of Excellence award to study ‘Digital Governance’. During the same time, and together with Stockholm University, I co-developed the only publicly accessible database of European Commission decisions on competition law (db-comp.eu), with funding from ESRC, and based on a research project funded by the Swedish Competition Commission. Over the years, I have served as a Visiting Professor at CUPL (Beijing), and as a Visiting Scholar at Oxford, Brown, and Delft universities, and more recently as a Senior Research Fellow at Loyola University Chicago.

Research publication details appear in the list below. My monograph Antitrust in the Decentralised Economy  published by Oxford University Press in 2025 is the first comprehensive application of competition law and policy in blockchain and fintech markets. In 2023, I was shortlisted for the Concurrence writing awards in the ‘General Antitrust’ category for my work on the goals of EU competition law.

Financial support for research is gratefully acknowledged to have been received over the years from ESRC, EU, the Fulbright Foundation, the Onassis Foundation, the Swedish Network for European Legal Studies, the Swedish Competition Authority, the Koch Foundation, the Hellenic Scholarship Foundation, the Institute for European Education and Culture, the Institute for Humane Studies, Google, Meta, Brown University, and FGV.

Sometimes, my work and research is featured in the media, among others in the Financial Times, Politico, Forbes, Marketwatch (Dow Jones), Business Insider, Channel 4, EuroNews, Coindesk, Cointelegraph, Sputnik News, Heise Online, Huffington Post Brazil, and The Conversation. 

I hold an S.J.D. from the University of Pennsylvania, an LL.M. from Harvard University, and an LL.B. and LL.M. from Aristotle University.

Research interests

Most of my work revolves around the intersection of technology and competition law. Industries I have particularly researched include blockchain, telecommunications, and online platforms. I have a broader interest in technology policy and how technology itself is an artefact and how this helps us understand how to regulate it. I also maintain an interest in online platform terms of service and how they affect fundamental rights such as privacy and freedom of expression.
