Hi! I am a Ph.D. student at Yonsei University, advised by Prof. Hyung-Chan An. I received my B.S. degree in Computer Science from Yonsei University. I expect to graduate in August 2024.

My major research interests reside in theoretical computer science. I am particularly interested in (but not limited to) online/approximation algorithms for combinatorial optimization problems.

I am eager to convey theoretical aspects of computer science to others, specifically in Korean. To this end, I am running a blog where I post several related topics including basics to recent work. Visit my blog 「Gazelle and Computer Science」 (in Korean) if interested.

I am a member of Yonsei CS theory student group. The group organizes seminar talks on the regular basis in order to study various interesting topics of theoretical computer science and to let people socialize and collaborate more easily. The group is open to any TCS lovers; contact me (or other organizers) if interested.
