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, discrete geometry, 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, Erdős-Falconer distance problem, 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.
