Personal profile


Please note that I am currently working full time as Vice President at Compass Lexecon until 31 March 2025.

I am Professor of Competition Economics. My research maps around various topics in competition law and economics, combining econometrics with novel data science methods. My current work focuses on digital markets, for example the impact of autonomous recommendation systems on competition, and I am Principal Investigator on a UKRI Trustworthy Autonomous Systems grant. I have previously worked on topics such as deterrence, reputation, and private sanctions, and have published extensively and done consultancy works on the ex-post evaluation of the impact of competition policy. I have PhDs in both economics and law, and have published in both economics and law journals of international excellence.

One of my impact case studies was submitted to REF2021 (all our UoA impact case studies were ranked as 4* or 3*).

Beside my academic achievements, I have several years of policy analysis experience working for the Hungarian Competition Authority and the OECD. I had also been a member of the Competition and Markets Authority's (CMA) Academic Board.

I have provided advice and delivered various reports for the European Commission, the OECD, UNCTAD, the World Bank and the UK CMA on issues related to economic impact evaluation and the estimation of the consumer benefits of competition policy. Some of these are publicly available:

Key Research Interests

My research is eclectic, and includes various topics in law and economics, in areas such as competition in digital markets, inequality, the analysis of the effect of private sanctions, measuring cartel detection and deterrence, the anti-competitive effects of mergers, and the ex post evaluation of the impact of competition enforcement including the analysis of the deterrent effect of law enforcement. Methodologically I am currently exploring how machine learning can contribute to studying social sciences, and especially competition law and economics. Currently I am involved in a number of projects on the economic impact of recommender systems.

Teaching Interests

At undergraduate level I teach Economics for Business, Economics for International Business, and Competition and Consumer Policy. I am module organiser for the MBA module International Economic Environment.
