Tianrun Gao

Shanghai, China

I am an incoming PhD student at the School of Computing and Data Science at The University of Hong Kong, starting in November 2026 under the supervision of Prof. Liangqiong Qu. I am currently a research intern at the AI Innovation and Incubation Institute at Fudan University and the Shanghai Academy of AI for Science, supervised by Prof. Long Wei.

I develop physics-aware simulators, generative models, and scientific agents for PDEs, coupled systems, engineering design, and control.

Research interests

Physics-aware AI for simulation, design, control, and discovery
PDEs, coupled physical systems, and fusion energy
Generative models and agentic systems for science
Automated numerical simulation for mechanics and engineering
