Bruegel Annual meeting 2014Welcome to my homepage. I am the Director of Bruegel, the independent and non-doctrinal institute on economic policy in Europe. A recognised academic and thought leader on the European economy and governance, global governance, finance and political economy, I regularly testify to the European Finance Ministers’ ECOFIN meeting, the European Parliament, the German Parliament (Bundestag), the UK’s House of Lords and the French Parliament (Assemblée Nationale/Sénat) and I am a regular speaker at international conferences.

Bruegel is regularly ranked among the top global think tanks. Bruegel ranked in the University of Pennsylvania’s think tank ranking #1 Worldwide (outside the US), #1 In Western Europe, #1 International economic policy, #1 outstanding policy-oriented Research Program, #3 worldwide after Brookings and Carnegie (see here pdf). In 2019, Bruegel also won the best think tank award in finance and economics for Europe by the Prospect Magazine. Bruegel publishes more than 40 papers/reports/books and around 250 blog posts per year with a team of around 65 (many in part time). The budget is close to €6 million and is to more than 80% funded by subscription revenues from Bruegel’s diverse membership of EU countries, international corporations and institutions. As director, I am the chief executive, the director of research, the editor in chief and a senior scholar. I lead a diverse and international team of globally recognized scholars and oversee the operational, communications and development teams.  To find out more about Bruegel, please check the annual reports published under my responsibility (202020192018201720162015, 2014, 2013).

From 2012-16, I was a member of the French prime minister’s Conseil d’Analyse Economique. In 2018, then IMF managing director Christine Lagarde appointed me to the external advisory group on surveillance to review the Fund’s priorities. In 2021, I was appointed to the G20 High level independent panel on pandemic prevention, preparedness and response (HLIP) under the co-chairs Tharman Shanmugaratnam, Lawrence H. Summers and Ngozi Okonjo-Iweala. In 2020, Business Insider ranked me one of the 28 most influential power players in Europe “hashing out the rules of everything”. I am a member of the Solvay Brussels School’s international advisory board of the Brussels Free University. I joined Bruegel in 2011 from the European Commission, where I worked on the macroeconomics of the euro area and the reform of euro area governance. Prior to joining the Commission, I was coordinating the research team on fiscal policy at Deutsche Bundesbank. I also worked as an adviser to the International Monetary Fund.

I hold a PhD in economics from the University of Bonn, studied in Bonn, Toulouse, Pittsburgh and Passau and previously taught economics at the University of Pittsburgh and at Université libre de Bruxelles. I have published numerous papers in academic journals (see below). I am fluent in German, English, French and know some Bulgarian and Spanish. My columns and policy work are published and/or cited in leading international media such as the Financial Times, the New York Times, Wall Street Journal, Caixin, Nikkei, El Pais, Le Monde, La Stampa, FAZ, Handelsblatt, Les Echos, BBC, ZDF, and others. Here is a profile of mine in Süddeutsche Zeitung.
