I'm a postdoctoral researcher at the University of Vienna, where I completed my Ph.D. in Mathematics under Philipp Grohs in 2024. Prior to that, I studied at the Technical University of Munich and Seoul National University, resulting in the attainment of an M.Sc. degree in pure Mathematics in 2020.
