CV (updated July 14, 2026).
A picture of me with the Big tilting object (courtesy of Evgeny Smirnov). Another picture of me, thinking about thesis topics for graduate students (courtesy of Jose Simental Rodriguez, my former graduate student). And this is how my current graduate students see the process (courtesy Xin Xu).
Learning seminars that I organized.
I'm in the editorial boards of Forum Math Pi and Sigma, Journal of the AMS, Journal of Combinatorial algebra, Selecta Mathematica and Transformation groups.
Here I post chapters of the book "Modern Introduction to Representation theory" (tentative title) that I'm writing.
In Summer 2026 I gave a lecture series at the Canada-USA Mathcamp. The topic is the Hasse-Minkowski theorem. The lecture notes are posted here.
In Fall 2026 I teach graduate course MATH 7720, Category O and Soergel theory. The webpage is here.
