My research revolves around crystallographic symmetries related to root systems, representations of Lie algebras and multiplicative invariant theory. Moreover, I am interested in computations over noncommutative algebras as well as exploiting algebraic structures in optimization. My doctoral thesis entitled "Groupes Cristallographiques et Polynômes de Chebyshev en Optimisation Globale" ("Crystallographic Groups and Chebyshev Polynomials in Global Optimization") was defended on December 15, 2022 at Inria d'Université Côte d'Azur. The jury consisted of Christine Bachoc, Laurent Baratchart (président du jury), Evelyne Hubert (directrice de thèse), Victor Magron, Gabriele Nebe and Frédéric Patras. The thesis is accessible in the library of the university and online. Currently, I am working on this problem. Our research group organizes a seminar on representation theory and beyond every fortnight.
