Biography
I 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.
Find more information about me in my CV.

Research
Topics
I 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 some questions from Lie theory, including representation theory of quantum groups, seen as deformations of Kac-Moody Lie algebras. In particular, the study of crystals and canonical bases provide a combinatorial setting linking all these problems.

Research articles
PhD thesis
I 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.
Programming
I 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 imaps and an affine Robinson-Schensted correspondence.
