刘佳润

I am a researcher of Unmanned Vehicle Dept., Cainiao Inc., Alibaba Group. I obtained my M.S. degree from the ZJU3DV group of State Key Lab of CAD&CG, Zhejiang University in 2025, advised by Prof. Guofeng Zhang. Before that, I got my bachelor degree from Zhejiang University as well. I am interested in 3D vision and generative models, as well as world models and applications in autonomous driving and embodied AI.
