am an ARC supported postdoc in the Algebra research group of the
University of Sydney, working
under the supervision of
Prof. Anthony Henderson. Here is my University of Sydney research
Before this I was an ANR supported postdoc in the Geometry team of the
Institut Elie Cartan de Lorraine in Nancy, working with Pierre-Emmanuel
Chaput. Before this I was a scientific collaborator in the
Representation theory team of Gunter
Malle at the University of Kaiserslautern. Before this I was a PhD
student of François
Digne in the Group theory team of the University of Amiens.

categorical incarnations (in particular Soergel bimodules).
groups attached to general Coxeter groups, Garside theory, and related
categorical incarnations (2-braid groups or Rouquier complexes,
zig-zag algebras, actions on triangulated categories, ...),
representation theory of braid groups.
- Dual approaches
in the study of Coxeter groups and Artin groups: dual braid monoids,
Hurwitz action in generated groups, noncrossing partition lattices,
Temperley-Lieb and diagram algebras.
- I will give a
talk in the Representation Theory session of the annual conference of
the Australian Mathematical Society in Adelaide, December 4 - 7th.
- I will give a
seminar talk in Tours on December 14th.
