I am an Assistant Professor at Université Paris Cité and a member of the Laboratoire de Linguistique Formelle. My research focuses on Artificial Intelligence, with a particular emphasis on Natural Language Processing — essentially, getting computers to understand and generate human language.
After completing a PhD in Computer Science specializing in Machine Learning, I spent several years working on statistical machine translation and the development of multilingual models. More recently, my research has shifted towards the analysis of Large Language Models (LLMs) such as ChatGPT. My goal is to understand what kind of knowledge—especially linguistic knowledge—these models capture and how they acquire it.
In addition to my research, I teach various NLP-related topics, including Transformer-based methods, as well as courses in data science. I also serve as the program director for the Master’s in Computational Linguistics at Université Paris Cité, a program designed to equip students with both theoretical and practical skills in NLP, preparing them for careers in industry or research through interdisciplinary training in computer science, data science, linguistics, and AI.
I'm the author of a popularization book, Faire parler les ordinateurs that explains the scientific challenges involved in developing computers capable of understanding and speaking, and explains all the elements involved in understanding how large language models like chatgpt work, as well as the societal and scientific challenges they raise.
