About me

I am a mathematician currently working in the Discrete Mathematics Group at the Institute for Basic Science (CI: Sang-il Oum ).  Before joining IBS, I was a research fellow in the School of Computational Sciences at the Korea Institute for Advanced Study (mentor: Jeong Han Kim). I earned my Ph.D. in 2021 from the University of Rochester, advised by Jonathan Pakianathan, and my Master's degree from Ewha Womans University*, under the guidance of Sangjib Kim. (*: adding "s" is not a typo.)

Research interests

I am primarily interested in how combinatorial ideas interact with other areas such as number theory, discrete geometry, (linear) algebra, topology, and related fields. 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:

character sum, cluster algebra, Diophantine tuple, distance matrix, Erdős-Falconer distance problem, genomic Schur function, incidence problem, multiset permutation, additive and multiplicative decomposition, (n,d,λ)-graph, orthogonal group, polynomial over finite fields, q-binomial coefficient, quadratic form, quasigroup, quasi-random (hyper)graph, quasirandom group, threshold function, 0-Hecke algebra.
