I am Professor of Finance at HEC Paris where I hold a chair from the HEC Foundation and a research fellow of the Centre for Economic Policy (CEPR). My research focuses on the determinants of financial markets liquidity, the production of information in these markets, their industrial organization, and their effect on the real economy. It is published in leading scholarly journals such as Journal of Finance, Review of Financial Studies, or Journal of Financial Economics. In 2021, I received a grant from the European Research Council (ERC) to work on the effects of AI and big data on information production in financial markets. I have received research awards from the Louis Bachelier Institute, the HEC Foundation, and the Analysis Group award for the best paper on Financial Markets and Institutions presented at the 2009 Western Finance Association (WFA) meetings.

I am currently co-managing editor of the Journal of Financial and Quantitative Analysis (JFQA) and an Associate Editor of the Journal of Economic Theory and the Journal of Finance, and a former Associate Editor of The Review of Financial Studies. I also served as co-editor of the Review of Finance from 2009 to 2013 and the Review of Asset Pricing Studies (RAPS). I co-authored, with Marco Pagano and Ailsa Röell, “Market Liquidity: Theory, Evidence and Policy” , a textbook on market liquidity published by Oxford University Press in 2013.
