About me

Currently working as a post-doc in Inria's Team TITANE, under the supervision of Pierre Alliez, with funding from 3IA Côte d'Azur.
Previously (2022->2024) a R&D software engineer at Siemens Digital Industries Software, in the team of Scott Canann, doing quad meshing & high quality triangulation for the CFD software Star-CCM+.
I earned my Ph.D. in computer science, Polycube Dominant Meshing, in Team Pixel under the supervision of Dmitry Sokolov, Nicolas Ray and Franck Ledoux. It won the second place in the French Computer Graphics Association's Ph.D. award.
