  • Associate Professor in Competition Law and Policy
  • Faculty of Laws

Dr Despoina (Deni) Mantzari joined the UCL Faculty of Laws in September 2018 as a Lecturer in Competition Law and Policy and was promoted to Associate Professor in October 2020. Prior to joining UCL, she was a Lecturer at the University of Reading School of Law and Programme Director of the LLM in International Commercial Law (2014-2018). Deni holds a PhD from UCL (AHRC doctoral scholarship), an LL.M in European Union Law (distinction) from UCL and a law degree from the National University of Athens, Greece.


In 2013-2014, Deni was a postdoctoral research fellow at the ESRC Centre for Competition Policy at the University of East Anglia, where she undertook research on behavioural economics and comparative (EU, US) antitrust law. In 2010-2011, she was a visiting researcher at the UC Berkeley Boalt Hall School of Law in the USA and in 2016-2017 she was a Fellow at the Institute of Advanced Legal Studies in London where she undertook research on the influence of economic evidence on the discretionary assessments of the UK utility regulators as part of her BA/Leverhulme Small Research Grant.


Deni is co-Director of the Centre for Law, Economics and Society at UCL, an associate fellow of the Centre of Competition Policy at the University of East Anglia and a Fellow of the UK Higher Education Academy. She is book review editor for the journal World Competition - Law and Economics Review (Kluwer Law), an associate editor for the Journal of Competition Law and Economics (OUP) and sits on the editorial board of the Journal of Antitrust Enforcement (OUP). Since 2016, Deni is General Editor for the 'Competition Law of the European Union' treatise published by LexisNexis, succeeding the leading Competition Law Professor, Valentine Korah.


Deni has been invited to the judicial training programme of the European Commission and as a guest lecturer in many institutions. Prior to joining academia, Deni worked as a trainee lawyer and qualified to practice law in Greece (Athens Bar Association).

Research Summary

Deni’s research cuts across competition law, consumer protection law and public law. She is interested in the interaction of competition law and regulation in a number of regulated industries (electronic communications, energy, pharmaceuticals) as well as in judicial review of competition authorities' and sector-specific regulators' decisions. Her work is distinctive in its comparative (EU, UK, US) and interdisciplinary orientation and draws on a range of social-scientific disciplines, including political science and economics. Her research combines doctrinal analysis with qualitative analysis and has been funded by the AHRC, the ESRC and the BA/Leverhulme Trust. Deni’s peer-reviewed articles have been published in generalist (Oxford Journal of Legal Studies, Modern Law Review) and specialist (Journal of Competition Law and Economics, Yearbook of European Law, Journal of Antitrust Enforcement) journals. Deni's monograph entitled: "Courts, Regulators and the Scrutiny of Economic Evidence - Comparative Perspectives" will be published by Oxford University Press in September 2022.
