I am Associate Professor of European Competition Law at the Europa Institute at Leiden University, where I also serve as the Academic Director of the LL.M. Programme in European Law.My main research and teaching interests lie in the fields of EU and comparative competition law (antitrust and State aid) and EU internal market law.The focus of my current research is twofold. The first strand is empirically oriented and investigates how competition authorities exercise their discretionary powers, especially in setting enforcement priorities. It also explores the role of third parties in structuring administrative discretion across various areas of EU (competition) law. The second strand examines the application of EU competition law to transnational private regulation, raising fundamental questions about how to give consideration to non-economic public interests, with a continued focus on sports governance as a case study.I am editor of the European Competition and Regulatory Law Review (CoRe), editor-in-chief of the Asser International Sports Law book series (Springer), and editorial board member of Voetbal- en Sportjuridische Zaken (Boom Juridisch) and the International Sports Law Journal (Springer).Before joining the Europa Institute in 2016, I was a senior researcher at the T.M.C. Asser Instituut in The Hague and a Visiting Professor of competition policy and media regulation at the Vrije Universiteit Brussel (VUB). I started my postdoctoral career at the Georgetown University Law Center’s Institute for International Economic Law (2011). During this time, I also served as a consultant in international antitrust for the US Federal Trade Commission. I previously was a visiting researcher at New York University (2009).I have an interdisciplinary academic background. I hold a doctoral degree in law (2011) and master’s degrees in international and European Law and in communication sciences from the VUB. My Ph.D. thesis, published as “Economic Efficiency: The Sole Concern of Modern Antitrust Policy? Non-efficiency Considerations under Article 101 TFEU" (Kluwer Law International 2012), examined the role of public interest considerations (beyond competition policy) in EU antitrust enforcement.
