About me

Welcome to my personal webpage. I am an Assistant Professor of Mathematics at Southwest Jiaotong University.

You can find my CV here: CV (Google Drive, update: 07.2025).

My research focuses on mathematical control theory for stochastic partial differential equations (SPDEs) and related inverse problems, which are fundamental for understanding systems affected by random disturbances.
