Homepage of Mikhail Gorsky
I am a postdoc at LAMFA at the Université de Picardie Jules Verne in Amiens. My position is supported by the ANR CHARMS. I spent the 2020 fall semester at the Hausdorff Research Institute for Mathematics in Bonn. In 2018-2020, I was a postdoc at the University of Stuttgart. Prior to that I was a visiting scientist at the Bielefeld University and an invited reseascher at IHES. In 2015-2017 I was a postdoctoral fellow at the Max Planck Institute of Mathematics in Bonn.

Since July 2021 José Simental Rodríguez and I are organizing an online seminar on cluster structures on coordinate rings of various varieties appearing in Lie theory and related to link invariants. It is organised as a part of the AIM Research Community on Link Homology.
Hall algebras and categorification of quantum groups
Cluster algebras and cluster categories
Quiver representations and quiver varieties
Coxeter combinatorics: subword complexes, Cambrian lattices, non-crossing partitions...
Categorification of knot invariants
