I am a research fellow in the department of mathematics at the Korea Institute for Advanced Study . I am interested in combinatorial problems connected with other areas such as symmetric functions, algebraic geometry and representation theory. Some of my topics of interest: Affine Schubert polynomials, Schubert calculus, Fomin-Kirillov algebras
