About

I am currently a temporary lecturer at LIPN in the Team CALIN. Previously, I was a PhD student in LaBRI, Bordeaux, under the supervision of Mireille Bousquet-Mélou and Charlotte Hardouin, where I studied the combinatorics of walks confined into a cone (my PhD defense will be in LaBRI, the 10th of February 2026) manuscript defense slides. My research revolves around enumerative combinatorics, graph theory, computer algebra and Galois theory of difference equations.
