About

I am a postdoc at TU Wien funded by the UNPAC Project. My research revolves around enumerative combinatorics, graph theory, computer algebra and Galois theory of difference equations. Previously, I was an ATER at Université Paris 13 in the Team CALIN. More 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 took place in LaBRI, the 10th of February 2026 manuscript defense slides.
