About meI am an SNSF Ambizione research fellow in the Testerman group.Before this, I was a research and teaching assistant in the group of Gerhard Hiss at the Lehrstuhl D für Mathematik in Aachen.
I completed my PhD in Tours under the supervision of Cédric Lecouvey and Nicolas Jacon.
See my CV for more information.

TopicsI am interested in combinatorial aspects in modular representation theory of reflection groups (and of their associated Hecke algebras), and of finite classical groups.
I also investigate questions from Lie theory, including representation theory of quantum groups, seen as deformations of Kac-Moody Lie algebras. In particular, categorification phenomenons (involving e.g. crystals and canonical bases) provide suprising links with the aforementioned groups and algebras.
Research articlesSee this list. My research articles can be found on arXiv.
PhD thesisI have defended my PhD thesis entitled Decomposition matrices for Ariki-Koike algebras and crystal isomorphisms in Fock spaces in July 2014. You can find it online here.
ProgrammingI have written a few python programs for computing affine type A crystals using the combinatorics of Fock spaces. Also, I implemented the corresponding crystal isomorphisms, Heisenberg crystals, Mullineux-type maps and an affine Robinson-Schensted correspondence.
For any particular request, do not hesitate to write me.
