I am currently a Research Assistant Professor (RAP) in the Department of Applied Mathematics at The Hong Kong Polytechnic University (PolyU). My research focuses on numerical analysis and scientific computing, with particular interests in:

I completed both my B.S. and Ph.D. degrees at Tsinghua University, where I worked under the guidance of Prof. Chunxiong Zheng on absorbing boundary conditions and the semiclassical Schrödinger equation. Afterward, I joined PolyU as a postdoctoral fellow, collaborating with Prof. Buyang Li on geometrical PDEs, fluid-structure interactions, and nonlinear dispersive equations.

I’m enthusiastic about connecting with fellow researchers and students. If you’re interested in collaborating on exciting numerical PDE projects, feel free to reach out!
