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.

TopicsMy preferred research topics lie at the interface of representation theory and algebraic combinatorics. I am also interested in interactions with other areas of mathematics. Some themes I like to think about are:
- (modular) representations of finite groups (Coxeter groups, finite groups of Lie type, etc),
- Hecke algebras, Cherednik algebras,
- Lie algebras, Kac-Moody algebras and associated quantum groups,
- crystal and canonical bases
- combinatorics on words, RSK correspondence,
- applications in probability (random walks, percolation, etc)
- enumerative combinatorics.
Research articlesSee the list above. 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.
