My research interest is the cohomological Hall algebra and its variants, and the categorical representation theory.
Currently I am working on constructing categorical algebraic action on the derived category of certain moduli spaces. For example, SchiffmannVasserot, FeiginTsymbaliuk and Negut studied the quantum toroidal algebra action on the Grothendieck group of Hilbert schemes of points on surfaces, which generalized the cohomology action by Nakajima and Grojnowski. I constructed a weak categorication for this action.
