I am a BRL postdoctoral researcher at DGIST starting in March 2025, mentored by Prof. Kangjin Han. I was a graduate student under Professor Antoine Vigneron in the Department of Computer Science and Engineering at UNIST.
My main research is in Computational Geometry, and I am interested in solving computational geometry problems using various mathematical fields such as combinatorics, hyperbolic geometry, algebraic geometry, and geometric group theory. I have a broad interest in theoretical computer science beyond computational geometry, though I do not claim expertise in every subfield.
Recently, I have been focusing on the following research problems. If you are interested in discussing these topics or exploring potential collaborations, please feel free to reach out to me via email. Depending on funding availability, I may also be able to invite you to our institution for further in-depth discussions.
