I am a Postdoctoral Associate in the Department of Mathematics at Yale university, mentored by Wilhelm Schlag, starting in July 2026.

I completed my Ph.D. in the Department of Mathematics at Penn State University in 2026 under the supervision of Toan T. Nguyen. 

I received my bachelor's degree in Mathematical Sciences at KAIST in 2021.

CV

Research Interests

I am interested in the analysis of nonlinear partial differential equations motivated by classical and quantum mean-field kinetic theory, especially in problems related to long-time behavior and stability theory.
