Introduction
Hello, I’m Jungho Ahn, a Ph.D. student at the Department of Mathematical Sciences in KAIST, supervised by Sang-il Oum, and a student researcher at the Discrete Mathematics Group (DIMAG) in the Institute for Basic Science (IBS). In the top picture, the left is me, the middle is my advisor Sang-il Oum, and the right is my lab mate Duksang Lee. The picture was taken on Jeju Island.
My research interests lie in structural graph theory, algorithmic graph theory, and complexity theory. In particular, I’m interested in graph parameters, especially twin-width, forbidden induced subgraphs or minors, parameterized complexity, kernelization, NP-hardness, and approximation algorithms for graph problems.
Since September 2022, I have been organizing the Workshop for Young Mathematicians in Korea with graduate students Dongjun Choi (Seoul National University), Beomho Kim (KAIST), Keunsu Kim (POSTECH), Yeongjong Kim (KAIST), and Sungsu Jeon (POSTECH). The purpose of the workshop is to build academic and social networks among graduate students studying mathematics in Korea. In the workshop, we invite graduate students and young doctors for introductory talks on their research and encourage graduate students to communicate with others in various research fields.
Since October 2021, I have been organizing the KAIST Math Graduate student Seminar (KMGS) with a Ph.D. student Yeongjong Kim and master’s students Beomho Kim and Hyunwoo Lee from KAIST. We organized the seminar hoping that many graduate students in the department of mathematical sciences of KAIST communicate academically and socially with each other. If you are a graduate student in the department hoping to make a talk, please submit the abstract of your talk by following the instructions on the KMGS site. It’s fine if the contents of your talk are not published.
Since March 2020, I have been running the YouTube channel FPT Complexity. You can see various lecture videos or conference talks about parameterized complexity there. If you have any comments on this channel or want to recommend other videos, channels, or playlists, please let me know via the email below. For more information about parameterized complexity, you can visit Parameterized Complexity Community Wiki.
You can also see my profile on the DIMAG site. Nice to meet you! 🙂
