I have over 25 years of competition experience. Before joining ABC economics, I was Head of European Competition Economics at NERA, Berlin, for over 7 years where I led over 120 competition and regulatory cases for various clients. My experience also includes over 8 years as senior official in DG Competition, Brussels, dealing with many merger and in particular also Article 102 cases and over two years at the OECD Competition Division, Paris.My experience covers all sectors and all areas of competition and regulatory economics, notably competitive effects of mergers, cartels, quantification of damage, abuse of dominance and state aid, as well as vertical and horizontal restraints. I have acted as economic expert witness in front of national and international arbitration tribunals, the European courts and EU Member State courts.I have worked on a wide range of competition and regulatory matters including large national or EU-level merger cases, abuse of dominance and horizontal cases in front of the European Commission or national authorities and worked on some of the largest damages claims in the EU. In addition, my team and I worked on various state aid and vertical cases as well as national merger cases in front of the CMA, the Bundeskartellamt or the Autorité de la Concurrence.I am a Full Professor at the Department of Economics and Quantitative Methods at the IÉSEG School of Management Paris and the Université Catholique de Lille, and a member of LEM-CNRS (Centre National de la Recherche Scientifique).At NERA I rebuilt the European Competition practice from scratch and ensured a competition presence in several EU Member States and the UK reaching an overall team size of over 30 economists mainly located in Berlin, Paris and London.I was a Senior Economist of the Directorate General for Competition of the European Commission, where I dealt with the review and scrutiny of hundreds of antitrust and merger decisions, the peer review panels and the sector inquiry framework.I was also Senior Economist at the Competition Division of the OECD where I oversaw the Working Party on Competition and Regulation. I have lectured and gave trainings at various competition authorities in Asia and in Europe.If you have a competition or arbitration related matter you’d like to discuss, or if you just need some general advice, please don’t hesitate to get in touch with me.
