Xingyu Ni

Peking University

I received my PhD in July 2025 from the School of Computer Science at Peking University, China, where I was supervised by Prof. Baoquan Chen. As a member of the Visual Computing and Learning Lab, I was also advised by Dr. Bin Wang and Dr. Mengyu Chu. In the area of fluid animation, I was remotely advised by Dr. Bo Zhu at Georgia Tech, USA. Earlier, I graduated from the Turing Class at Peking University in July 2020, earning dual bachelor’s degrees in Computer Science and Physics.

My research focuses on physically-based visual computing, with a specialization in physical simulation. My academic ambition is to comprehend and reproduce kinetics and dynamics of the real world in a virtual counterpart, building theoretical foundations to reveal the physical principles. In the past years, I have extensive experience in the creation of dynamic physical scenes, particularly in multi-physics coupling and developing novel geometric representations for high-fidelity simulation and rendering. Currently, I am exploring innovative methods to bridge physical scene creation and comprehension, and to enhance traditional graphics pipelines with AI.
