Research Assistant Professor at the Beijing Institute of Mathematical Sciences and Applications (BIMSA), Huairou District, Beijing, China (it is sponsored by Tsinghua University and directed by Prof. Shing-Tung Yau).

Research interest: Operator algebras, von Neumann algebras, subfactors, planar algebras, algebraic combinatorics, finite group theory, fusion categories, vertex operators algebras, infinite dimensional Lie algebras, conformal field theory, noncommutative geometry.

I'm mainly active on MathOverflow.
