I am a mathematician working in algebraic combinatorics, algebraic geometry and Lie theory. Since 2023 I am a postdoc at TU Berlin in Michael Joswig's "Discrete Mathematics/Geometry" research group.
Until 2022 I worked at Skoltech and HSE in Moscow and prior to that I was a postdoc at the Max Planck Institute for Mathematics in Bonn.
I'm always happy to discuss: flag varieties and Grassmannians, tropical geometry, Gröbner theory, Lie algebra representations, toric geometry, polyhedra, posets and lattices, matroids, symmetric functions and cluster algebras.
The "kh" in my last name is a hard /h/ sound, like in "hat".
My detailed CV.
My papers on the arXiv (in slightly non-chronological order).
In WS 2024/25 I gave lectures for the "Topology" course at TU Berlin, here are my lecture notes. For further details please refer to the ISIS page.
I currently co-organize the Discrete Mathematics and Discrete Geometry seminar at TU Berlin, please email me for questions concerning this seminar.
In 2019-2022 I co-organized the now-defunct HSE/Skoltech Seminar on Lie algebras and applications. We had a good run, a detailed archive and many recordings are still available.
