Hi, I am Jongseo, an undergraduate student pursuing a degree in computer science and mathematics at KAIST.

I am interested in theoretical computer science, algorithm design, combinatorial optimization, and graph theory. I have taken various courses in these fields, including graph theory, matroid theory, and combinatorics. I have also participated in several algorithmic programming competitions and got awards.

I am currently studying and researching about approximation algorithms at the Combinatorial Optimization Laboratory of Yonsei University in South Korea. I also have an industrial experience about auctions/bidding, which is related to the field of algorithm design.

I am eager to continue my studies and research in the field of theoretical computer science.
