About

Hi, here's Shuo, a learner of robotics.

I'm a Senior Research Engineer at Cortex Robot, Inc. (Cortex AI) in San Francisco, where I work on robot data from both the real world and simulation, on human egocentric data, and on deploying foundation models to real robots.

Previously, I earned my M.S. in ECE from the University of Washington. I also spent my time as a student researcher with the Perceptual Reasoning and Interaction Research (PRIOR) team at the Allen Institute for AI (AI2), co-advised by Prof. Ranjay Krishna and Prof. Jiafei Duan. Before UW, I earned my B.E. in Robot Engineering from Southeast University, where I worked with Prof. Chenxing Wang.

More broadly, I work on robot learning: scaling the data robots learn from, building foundation models for robot manipulation, and controlling them for real-world deployment. If you'd like to chat, please feel free to reach out — always happy to meet up in SF and the Bay Area!
