I am currently a first-year Ph.D. student at the State Key Lab of CAD&CG, Zhejiang University (ZJU), advised by Prof. Kun Zhou (ACM/IEEE Fellow).

Previously, I obtained my M.Phil. degree from The Hong Kong University of Science and Technology (Guangzhou) in 2025, where I was advised by Prof. Yuzhe Ma. I received my B.E. degree in Microelectronics from Sun Yat-sen University (SYSU) in 2023.

My research interests primarily lie in Computer Graphics and AI for Science. I am particularly interested in Physics-based Simulation and applying machine learning techniques (such as PINNs and Operator Learning) to solve complex physical problems.
