I am a tenured CNRS researcher and an Associate Professor at the University Paris Dauphine - PSL.  My work aims to document the evolution of contemporary international finance and the ways in which it interacts with public action. Among others, I have provided empirical evidence that a large part of international financial transactions are associated with tax avoidance schemes;  I have also shown empirically that speculative transactions on a small derivative financial market can drive undelying government bond prices. More recently, I have published a book tracing back the transformations of French government intervention since 1949. I engage in regular dialogue with politicians and I make regular appearances in the media.

I am a member of the board of directors Banque de France and a member of the sicentific board of the museum of economics in Paris.
