I work on the determinants of financial markets liquidity and informativeness, the industrial organization of these markets, and their effect on the real economy. My most recent papers are on Big Data and new trading technologies, OTC markets, and the effects of stock markets on firms’ decisions (investment, product choices etc.). In 2021, I received a European Research Council (ERC) Advanced Grant for a five years research project on the impact of Big Data and Artificial Intelligence on financial markets and corporate investment. I am co-managing editor of the Journal of Financial and Quantitative Analysis (JFQA) since Sept 1, 2021. I am visiting CEMFI in Madrid from January to June 2022.
