Seminars that I am organizing or have organized
I'm in the editorial boards of Journal of Combinatorial algebra, Selecta Mathematica and Transformation groups.
In Spring 2021, I coorganize a learning seminar on quantum groups. This is a part of activities of the IAS special year on Geometric and Modular representation theory.
