Undergraduate Thesis, Tsinghua University, Undergraduate Researcher 09/2025 - Present
- Project: Simulation and Control of String-like Structures, Advisor: Prof. Tao Du
Implementing high-performance Discrete Elastic Rods (DER) simulation with collision handling, optimized via NVIDIA Warp; currently employing CMA-ES (preliminary) to explore bio-inspired locomotion for string-like robots.
Hao Su Lab, University of California San Diego, Research Intern 02/2025 - 08/2025
- Project: Latte Art Optimization, Advisor: Prof. Hao Su
Developing a differentiable two-fluid SPH simulator coupled with a differentiable renderer to optimize the generation of latte art and analyzing gradient error in differentiable SPH. Leveraged NVIDIA Warp to achieve GPU acceleration.
