Short Bio

Welcome to my homepage. I am a PhD student in the Department of Mathematics at the Chinese University of Hong Kong, under the supervision of Professor Bangti Jin. Previously, I received my Bachelor of Economics at Shanghai University of Finance and Economics in 2023.

My research lies at the intersection of inverse problems, statistical inference, and uncertainty quantification, with a focus on PDE-constrained applications.

Research Interests

• Inverse problems for partial differential equations
• Bayesian nonparametric statistics
• Numerical analysis
