Stéphane joined Oxera as a Principal in September 2020. He has expertise in competition law, with experience both as a consultant and as an enforcer. He was previously a case handler at the European Commission’s Directorate-General for Competition, where he worked for six years. Stéphane’s work for the Commission was shared equally between merger control and antitrust investigations, and he had a particular focus on the following sectors: energy IT, the Internet, media and telecommunications.

Before joining the Commission, Stéphane worked as an economist for eight years in two leading economics consultancies in the field of competition policy. He provided economic advice to companies in relation to mergers, horizontal and vertical agreements, and abuse of dominance—mostly in the context of investigations by the Commission and other competition authorities in Europe, but also in the context of private litigation. Stéphane’s experience in the private sector covers a wide range of sectors including the Internet, media, pharmaceuticals, telecommunications, consumer electronics, air transport, basic industries, manufacturing, FMCG, and banking.
