I am Full Professor and the Head of the Department of Economics and Social Sciences at Telecom ParisTech.

My research is interested in how the Internet and the digital revolution are transforming the money, the bank and the payment systems as well as the media and advertising industries.

I collaborate with colleagues in Economics, Statistics and Computer sciences from universities, public institutions and private research companies. Beyond academic journals, some of my recent works have been published in central banks' working paper series such as the European Central Bank, the Federal Reserve Bank of Boston, the Bank of Canada, De Nederlandsche Bank, the Deutsche Bundesbank, the Austrian Central Bank, and the Colombian Central Bank.

I serve as an Associate Editor for Electronic Commerce Research and Application.

I am the co-founder of the Chair 'Digital Finance' (with Marianne Verdier) in partnership with Institut Louis Bachelier.


As a Member of the Scientific Committee of the Center for the Study of Advertising Media (Centre d'Etude des Supports de Publicité), I contribute to audit and control media research. I am mostly involved in activities related to TV, Internet and mobile audiences, and specific topics such as advertising viewability and invalid traffic.

I develop several research programs with banks, payment card networks, and central banks to study how financial and technological innovations are transforming individual payment decisions, sectoral regulations and monetary policies.
