I am a Professor of Economics at Université Paris-Saclay and an AI consultant at the Banque de France. My research focuses on the economic and societal impact of digital technologies and artificial intelligence, with a particular emphasis on large language models. I combine causal inference, machine learning, and large-scale behavioral data to study how these technologies transform scientific research, information ecosystems, and economic decision-making.
