CV (updated 2024)

I'm a SNU Science Fellow at Seoul National University (SNU). I am interested in Symmetric function theory, the ASEP, Schubert polynomials, orthogonal polynomials and Ehrhart theory.

-Lusztig q-weight multiplicities and KR crystals (with Hyeonjae Choi and Seung Jin Lee)

-Extending the science fiction and the Loehr--Warrington formula (with Jaeseong Oh)

-Shuffle formula in science fiction for Macdonald polynomials (with Seung Jin Lee, Jaeseong Oh), Compositio Mathematica accepted

-Toward Butler's conjecture (with Seung Jin Lee, Jaeseong Oh)

-Techniques in equivariant Ehrhart theory (with Sophia Elia, Mariel Supina), Annals of Combinatorics (2023).

-Negative moments of orthgonal polynomials (with Jihyeug Jang, Jang soo Kim, Minho Song, U-Keun Song, Forum of Mathematics, Sigma (2023)

-Schubert polynomials, the inhomogeneous TASEP, and evil-avoiding permutations (with Lauren Williams), International Mathematical Research Notices (2022)

-Combinatorial formulas for the coefficients of the Al-Salam-Chihara polynomials

-A combinatorial formula for the Ehrhart h^{*}-vector of the hypersimplex , J. Combin. Theory Ser. A , 173 (2020)
