(Last update: May 12, 2025.)
I'm a research fellow in the School of Computational Sciences at KIAS, Seoul, South Korea. (Mentor: Jeong Han Kim)
Before joining KIAS, I was a postdoctoral fellow in the research group ECOPRO (Extremal Combinatorics and Probability Group) led by Prof. Hong Liu at the IBS headquarters, Seoul, South Korea.
I obtained my Ph.D. degree from the Department of Mathematical Sciences at KAIST in February 2023 under the supervision of Prof. Andreas Holmsen.
My research interests are Discrete Geometry and Topological Combinatorics. I'm mainly interested in Helly-type theorems, Ramsey-type results in discrete geometry, and combinatorial properties of d-representable, d-collapsible and d-Leray complexes.
Here is my CV.
