I am an Assistant Professor (tenure-track) in the Department of Mathematics at Hanyang University.

Previously, I held the following positions:

• CMC Fellow (Hyo Chul Myung Assistant Professor)
  June E Huh Center for Mathematical Challenges in Korea Institute for Advanced Study (KIAS), February 2024~August 2025

• Research Fellow
  School of Mathematics at KIAS mentored by Prof. Kyeongsu Choi, March 2022~January 2024

• Postdoctoral Researcher
  Basic Science Research Institute, Pohang University of Science and Technology, March 2021~February 2022

I earned my Ph.D. in the Department of Mathematics at Pohang University of Science and Technology (POSTECH)
under the advisement of Yun Sung Choi (POSTECH) and Manuel Maestre (University of Valencia) in February 2021.
