Guian Fang

I am a Ph.D. student at Show Lab, National University of Singapore, advised by Prof. Mike Zheng Shou.

Previously, I received my B.Eng. in Intelligent Science and Technology at the School of Intelligent Systems Engineering, Sun Yat-sen University, advised by Xiaodan Liang (梁小丹), co-supervised by Shengcai Liao.

My research centers on generative video models and world models for long-form visual generation, with recent work on video diffusion distillation and embodied intelligence.

Beyond research, I build agentic visual-generation pipelines and runtime infrastructure for coding agents, and I am open to collaboration.
