About Me

Wei Xiao 肖巍

  • Reinforcement Learning
  • Embodied Intelligence

Hi! I'm a PhD student at Fudan University and Shanghai Innovation Institute, advised by Li Zhang. I also work with Yao (Mark) Mu at ScaleLab@SJTU.

I've had the chance to work on reinforcement learning and embodied intelligence at Shanghai AI Lab, XPENG Robotics, and MiLab@Westlake. I earned my B.Eng. in Automation at Xiamen University, where I was advised by Qifeng Zhou.

I want to build end-to-end, general-purpose robotic systems that can eventually surpass human capabilities. I'm especially excited about robots learning beyond what we can demonstrate. I believe reinforcement learning and scalable learning approaches, such as world models and unsupervised/self-supervised learning, are key to getting there with less reliance on teleoperation data.

Feel free to drop me an email if you're interested in my research, have a collaboration in mind, or just want to chat!
