Representation theory · Shanghai

Algebraic structures,
from symmetry to categorification.

I am a Research Fellow (tenure track) at East China Normal University. I work in representation theory, with an emphasis on Lie algebras, quantum groups and quantum symmetric pairs, diagrammatic categorification, and their connections with geometry.
