I am a researcher in natural language processing (NLP) in the Lattice team (CNRS). I got my PhD in 2019 from the university of Lille (France). I prepared it in the Magnet team at Inria Lille, under the supervision of Pascal Denis and Marc Tommasi. I then did a post-doc of 18 months at the university of A Coruña (Spain) in the FastParse team of Carlos Gómez-Rodríguez until december 2020.

Research Interests

I am interested in several aspects of natural languages. Most of my work has focused on syntactic analysis in a multilingual environment. But I am also interested in morphological analysis, low resource languages (with big populations or with very small ones), historical linguistics, epigraphy and cross-lingual annotation consistency, amongst other.

I am also interested in computability and complexity theory and related areas of computer science and mathematics.

In Progress

I am the main annotator behind the 𐌉𐌊𐌖𐌅𐌉𐌍𐌀 dependency treebank, a Universal Dependencies treebank for Umbrian.

I have a project about oïl languages that aims at understanding the role of neighbouring languages (Germanic, Celtic and other Romance languages) on the syntactic evolution of these languages from the northern half of France, Belgium, Luxembourg, Switzerland and the Channel islands.

Internships

I am always happy to have interns. I have a running language evolution project that is currently occupied but might eventually reopen, see this for more details.
