Final-year undergraduate @ School of Software, Tsinghua University.
My long-term research goal is twofold: on one hand, to tackle fundamental challenges in traditional theoretical and numerical frameworks of graphics and geometry; on the other, to draw inspiration from classical graphics methodologies to advance emerging domains.
During my undergraduate studies, I have been fortunate to collaborate with Professor Feng Xu, and Professor Hao Pan at Tsinghua University. Besides, I have worked with Professor Shuang Zhao at University of Illinois Urbana-Champaign, Professor Toshiya Hachisuka at University of Waterloo, and Dr. Ryusuke Sugimoto at Institute of Science and Technology Austria.
7 Oct, 2025 – I will be at SIGGRAPH Asia 2025 to present my solo short paper. The presentation will unfold in the form of a magical story set in a fictional world. See you in Hong Kong!
Below are some stills from the show.
Publications
† denotes the corresponding (or sole) author.

My recent interests lie in stochastic methods for solving (boundary) integral equations. Ongoing works also relate to methods of fundamental solutions.
The following publications are ordered by time.

A Caveat on Differentiating Time-Domain Wave Boundary Integral Equations
Physicists usually do not worry about the order of integration and differentiation, since in most cases the functions involved are at least C^1-continuous. However, one cannot always take this for granted. Read more.

Hemisphere Sampling or Spherical Sampling: A Small Detail of Importance Sampling the Poisson Kernel in Walk on Boundary
In WoBToolbox, there is a seemingly puzzling step when sampling this term: the author uses uniform hemisphere sampling to generate rays, and this hemisphere is not aligned with the geometric normal of the boundary. Read more.
