About me

Hi! I am a postdoctoral researcher at University of Twente, working with Johannes Schmidt-Hieber. Before that, I completed my Ph.D. studies at the Seoul National University under the supervision of Yongdai Kim in 2024. 

My research focuses on statistical machine learning and deep learning theory.

Currently, I’m working on a project funded by the European Research Council that extends mathematics and statistics from artificial neural networks to biological neural networks.
