Hello!

I am a PhD student in mathematics working in extremal combinatorics and graph theory, with a particular interest in graph homomorphism inequalities.

I am currently at Yonsei University, supervised by Joonkyung Lee. I got a Bachelor’s in Mathematics at Pohang University of Science and Technology.

News

I am visiting Caltech from January to July 2026, hosted by David Conlon.

During my visit, I’ll be in the U.S. and would be happy to consider invitations for seminars or research meetings; please feel free to contact me.
