Jean Wanningen (1957) has had a varied career. A trained philosopher of science, he began his career at the investment bank Pierson, Heldring & Pierson, where he retrained as an economist. As an economist, he worked in the venture capital industry, the mobile data industry and as an independent entrepreneur. During this period he appeared several times in commissariats and as a consultant. The euro crisis was the reason for him to deal intensively with the European Union: first as an economist in the "Lion's Den" (Brussels), then as author and editor of the news and column website De Dagelijkse Standaard. Through his activities in the scientific world, in the financial sector, in companies, in politics and as an independent entrepreneur, he has been able to acquire a wide range of knowledge. His knowledge and experience play an important role in assessing our complex world today. In his spare time he enjoys mathematics and golf; he also enjoys playing the piano and chess, and he enjoys fishing.
