Mr. Gyselen joined Arnold & Porter after a long career in government, primarily at the European Commission. His competition law practice encompasses advice and representation before EU and national agencies on merger control, abusive conduct, cartels, other restrictive practices, and state aids.
Prior to joining the firm, Mr. Gyselen held several senior positions at the European Commission's Directorate-General for Competition (DG COMP). As Head of Unit, he played a key role in many high-profile cartel and abuse cases, in particular in the sectors of banking, insurance, food, and pharmaceuticals. Prior to that, as special assistant to the Director-General in DG COMP, he oversaw the entire range of EU competition enforcement policy activities, including the introduction of EC merger control, and acted as liaison officer between DG COMP and the Commissioner in charge of competition policy and his personal staff.
In the earlier years of his career, Mr. Gyselen was a member of the European Commission's Legal Service and a law clerk at the European Court of Justice in Luxembourg where he clerked for Judge Joliet.
Mr. Gyselen is involved in EC competition cases "across the board" (i.e., mergers, antitrust, and state aids). He also represents a number of international clients in antitrust cases pending before the Belgian competition authority. Since 2008, Mr. Gyselen is a Non-Governmental Advisor (NGA) to the EC. In that capacity, he has spoken at annual conferences or workshops organized by the International Competition Network (ICN).
