معرفی
Nathan Chapelier-Laget is an Associate Professor at the University of the Littoral Opal Coast, France, affiliated with the LMPA (Laboratory of Pure and Applied Mathematics). He is a core member of the ANR CORTIPOM project (Combinatorial Representation Theory and Interaction with Probabilistic Models) and co-organizes the weekly ADA team seminar alongside Lucille Devin, Pierre-Louis Giscard, and Ilia Smilga.
His academic trajectory includes:
- Humboldt research fellowship at Ruhr University Bochum, Germany (2024-2026, declined after 6 months)
- Postdoctoral researcher at the University of Sydney, Australia (2022-2023) under James Parkinson
- CNRS postdoctoral position at Université de Tours and Institut Denis Poisson, France (2021-2022) with Thomas Gobet, Jérémie Guilhot, and Cédric Lecouvey
He earned his Ph.D. in Mathematics from Université du Québec à Montréal in 2021 under Christophe Hohlweg and Hugh Thomas. His research integrates combinatorial representation theory with probabilistic models through ANR CORTIPOM, focusing on structural properties of algebraic and geometric systems.
Dr. Chapelier-Laget's scholarly work centers on Coxeter groups, Weyl and affine Weyl groups, Bruhat order, Kazhdan-Lusztig cells, representations of Hecke algebras, Shi regions, automata theory, lattice theory, toric varieties, Lie algebras, Kac-Moody algebras, and number theory via diophantine equations and core partitions. His methodology bridges abstract algebra with computational approaches to solve complex combinatorial problems.
His recognition includes the Humboldt research fellowship award. He has contributed to academic service as a member of the FPSAC 2024 organizing committee and through co-organization of the ADA seminar series.
Current engagements include the FPSAC 2025 conference in Sapporo (July 2025), GT CombAlg and Sage Days in Paris (June 2025), and the ANR CORTIPOM closing conference in Le Croisic (June 2025). His laboratory work is conducted within the LMPA framework at ULCO's Calais campus.
