About Me
I am a Computer Science Ph.D. student at MultiPLES Lab, UCLA Department of Mathematics,
co-advised by Prof. Chenfanfu Jiang and Prof. Demetri Terzopoulos.
I graduated with honors from the University of Electronic Science and Technology of China
(UESTC),
and I was a Research & Development intern at Taichi Graphics, where I was fortunate enough to be supervised by
Dr. Tiantian Liu.
My research interests lie in computer graphics and computational physics.
In particular, I devote myself to physically-based simulation and high-performance computing
on modern graphics architecture.

MeshTaichi: A Compiler for Efficient Mesh-based Operations

We propose MeshTaichi, a novel mesh compiler that provides an intuitive programming
model for efficient mesh-based operations. MeshTaichi achieves a consistent speedup ranging from 1.4
times to 6 times, compared to state-of-the-art mesh data structures and compilers.

Real-time Physics Engine Based on MPM & PBD

We have proposed a real-time physics engine that can handle various materials and
phenomena, including deformable objects, granular objects and water. Furthermore, based on the latest
MLS-MPM method proposed by academia, our engine can handle the coupling of water and sand.

Experiences
Research, development and deployment of MeshTaichi extension
A research program. Developed and deployed a novel mesh compiler based on Taichi that provides an intuitive programming model for efficient mesh-based operations. Devised the programming interface and backend code generation. Implemented XPBD, Projective Dynamics, and Lagrangian-force MPM for experiments. Submitted a patent. Work published in SIGGRAPH Asia 2022.

Development of prototype of Taichi's Vulkan GPU backend
Developed and deployed an IR builder to convert CHI IR (Taichi's intermediate representation) to SPIR-V, which could be executed by Vulkan SDK, as a solution for non-CUDA environment and AOT compilation. Technical talks presented on TaichiCon01/02.
