IIIS (“Yao Class”)

Undergraduate Thesis, Tsinghua University, Undergraduate Researcher 09/2025 - 05/2026
- Project: Simulation and Control of String-like Structures, Advisor: Prof. Tao Du
Developed an NVIDIA Warp-based DER simulation and control framework for string-like aquatic soft bodies, including curvature-driven actuation, fluid drag, collision handling, and simulation-based optimization with CMA-ES, TuRBO, and RCFM.
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.
