Research Interests: Combinatorics, Representation Theory, Computer Algebra.

I essentially work on hyperplane arrangements and related structures such as oriented matroids, reflection groups, and quon algebras. My PhD thesis mainly deals with descent algebras by determining the spectral properties of their regular representations. These algebras are linked with several mathematical structures such as quasisymmetric polynomials and completely positive maps. My Habilitation thesis studies conditional oriented matroids which are common generalizations of oriented matroids and lopsided sets. It particularly provides a generalization of the Topological Representation Theorem by proving that conditional oriented matroids correspond to topoplane arrangements.
