Jiarun Liu 刘佳润

I work on autonomous driving research at NIO Inc. Previously, I was an algorithm engineer at Cainiao, Alibaba Group.

I received my M.S. from the ZJU3DV group, State Key Lab of CAD&CG, Zhejiang University, advised by Prof. Guofeng Zhang. My interests span 3D vision, generative and world models, autonomous driving, and embodied AI.
