Since 2023, I have been a postdoctoral researcher in mathematics at the Collège de France under the supervision of Timothy Gowers.
Recently, I was honoured to receive the Prix de la Fondation Hugot du Collège de France.
I am a member of the ANR project CrocQG (Crossroads in the theory of compact quantum groups).
You may find my CV here.
Here is a list of my publications, ordered by their first appearance online. See also arXiv and Google Scholar.
