About me

I am a mathematician currently working in the Discrete Mathematics Group at the Institute for Basic Science (IBS) in Daejeon, Korea 🇰🇷 (CI: Sang-il Oum).  Before joining IBS, I was a research fellow at the Korea Institute for Advanced Study (KIAS) 🇰🇷. I earned my Ph.D. in 2021 from the University of Rochester in the U.S. 🇺🇸, advised by Jonathan Pakianathan, and my M.Sc. from Ewha Womans University* in Seoul 🇰🇷, under the guidance of Sangjib Kim. (*: adding "s" is not a typo.)

Research interests

My work focuses on additive, arithmetic, and algebraic combinatorics, often intersecting with extremal combinatorics and spectral graph theory. Much of my research has focused on problems over finite fields, while I remain broadly interested in many topics in combinatorics. Here are some keywords related to my research so far (including ongoing projects):

character sum(5), cluster algebra, Diophantine tuple(5), expander mixing lemma(4), Erdős-Falconer distance problem, Fibonacci-like unimodal map, genomic Schur function, incidence bound(3), multiset permutation, multiplicative decomposition(2), multiplicative subgroup(2), (n,d,λ)-graph(2), 1-factorization, orthogonal group(3), Paley graph(3), polynomial over finite fields(5), product representation, q-binomial coefficient(3), q-Laplacian matrix, quadratic form(4), quasigroup, quasi-random (hyper)graph(2), quadratic residue(10), threshold function, tree distance matrix, 0-Hecke algebra.
