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 in 2016 from Ewha Womans University*, under the guidance of Sangjib Kim. (*: adding "s" is not a typo.) Here is my CV. (Updated on September 20, 2025)

Research interests

I am primarily interested in Combinatorics, especially interlacing with other areas such as number theory, algebra, topology, and so on. Much of my research has been done in finite fields, but I am broadly interested in various areas of combinatorics. Here are some keywords related to my research so far: 

character sum, cluster algebra, Diophantine tuple, genomic Schur function, incidence problem, multiset permutation, 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.
