Boris Tsvelikhovskiy finished his Ph.D. in 2020 at Northeastern University, under the supervision of Ivan Losev and Gordana Todorov. His Ph.D. thesis was dedicated to the study of categories O on Nakajima quiver varieties associated to bouquet graphs.
While working toward his master’s degree in Higher School of Economics, he studied the combinatorial properties of shuffle algebras with two parameters and, in particular, obtained the Hilbert series for the quotients of these algebras by ideals of certain type.
