Pengxiang Ding

Researcher & Founder

Pengxiang Ding 丁鹏翔

I am the founder and CEO of Symbiosis Robotics (共生知行), where we build foundation models for whole-body humanoid intelligence.

My research focuses on vision-language-action models and whole-body control.

I am a Ph.D. student at Zhejiang University in a joint program with Westlake University, advised by Prof. Donglin Wang in the Machine Intelligence Laboratory (MiLAB).

Previously, I received my M.Sc. from the School of Artificial Intelligence at BUPT in 2022, advised by Prof. Jianqin Yin.
