  • I released a reference implementation of our SIGGRAPH North America 2023 paper, "A Practical Walk-on-Boundary Method for Boundary Value Problems." The code is available here, and the paper is available here. (July 16, 2023)

    • About Me

    I am a PhD candidate in computer science under the supervision of Prof. Toshiya Hachisuka and Prof. Christopher Batty at the University of Waterloo. Before this, I received my bachelor's degree in computer science and mathematics from HKUST, where I worked with Prof. Pedro V. Sander. My research interests lie in computer graphics, particularly in physically based animation. In my PhD studies, I am focusing on the use of integral equations and Monte Carlo methods for non-rendering tasks.
