Real-world AI is won by systems, not models.

Founder & CTO of Chestnut Robotics (previously TetherIA), building dexterous robots for the real world. Tech lead for the planning model behind XPeng's production end-to-end driving; planning foundation models at Waymo. Physicist by training, computer vision by trade. Author of Physical AI Deep Dives.

Building — Chestnut Robotics

The data-driven dexterous hand, and the pipeline that trains it.

We build the Aero Hand and the data engine behind it — egocentric, high-fidelity capture that turns human demonstrations into robot skill. Aero Hand (18-DOF, sub-mm) · Aero UMI (capture exoskeleton) · GAIN3D (3D reconstruction) · a robotic foundation model on top.

Writing — Physical AI Deep Dives

I think in public about hard problems in physical AI.

The most useful split in robot learning isn't VLA vs. world model — it's system thinking vs. model thinking.

About

A researcher who builds in production.

I trained as a physicist (USTC, 2010–14), then moved into computer vision for my PhD, working on medical image analysis (Virginia Tech, 2014–19). From 2019 to 2025 I carried vision into autonomous driving through three of the field's paradigm shifts — monocular 3D detection, learning-based planning, then end-to-end foundation models, the last shipped to production at XPeng. In 2025 I cofounded Chestnut Robotics to do the same for robots. Every move has followed one read — a field AI had just cracked open.

Focus — dexterous manipulation, data engines, foundation models for the physical world.
Belief — real-world AI is a systems problem before it's a model problem.
Now — the Aero Hand, and teaching robots to use it.
