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, Schiffmann-Vasserot, Feigin-Tsymbaliuk 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.
