I am a Maître de Conférences (~associate professor) at Université Paris-Saclay where I am the head of the Artificial Intelligence master. I conduct my research in the Spoken Language Processing / Traitement du Langage Parlé group at LISN (ex LIMSI). I am a board member of the ATALA, a French association that promotes and animates research in natural language processing.

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

I also give training in deep learning for Natural Language Processing for the private sector via CNRS formation entreprise.

Open positions

Lucas Ondel and I have two open postdoc positions:

• Multilingual speech recognition

• Speech recogntion for constrained compute environment

Feel free to contact us be email for more information. You can apply even if you didn't finish your PhD yet. We are flexible on the start date.

Special issue of the TAL journal: robustness and limitations of NLP models

This thematic issue of the TAL journal aims at questioning the robustness and limits of modern NLP models. All standard NLP tasks can be considered. Works on other languages than French and English are warmly welcomed.

Paper submission deadline : May 12th, 2023

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).
