I am a Maître de Conférences (~associate professor) at Sorbonne Université. I conduct my research in the MLIA group at ISIR. I am a board member of the ATALA, a French association that promotes and animates research in natural language processing.

My research focuses on Natural Language Processing and Machine Learning. I am especially interested in inference algorithms for structured prediction.

Quick Presentation

I obtained a Ph.D. in 2018 from Université Paris 13 under the supervision of Joseph Le Roux and Adeline Nazarenko. We worked with Mathieu Lacroix on using combinatorial optimization techniques (Lagrangian relaxation) to solve efficiently problems related to syntactic parsing with mildly context-sensitive grammars (e.g. Lexicalized Tree Adjoining Grammars).

My Ph.D. was supported by the Labex EFL, a public grant overseen by the French National Research Agency (ANR) as part of the Investissements d’Avenir program (ANR-10-LABX-0083).

From November 2017 to August 2018, I was postdoctoral researcher working with Ivan Titov. I was formally employed by the University of Amsterdam but I spent my time there as a visitor at the University of Edinburgh (EdinburghNLP group).

From September 2019 to August 2023, I was an associate professor at Université Paris-Saclay where I was the head of the Artificial Intelligence master. I conducted my research in the Spoken Language Processing / Traitement du Langage Parlé group at LISN (ex LIMSI). I am currently on leave from this position.
