AI Researcher

👋👋Hi, I'm Chi! I am currently working full-time with Prof. Yiming Li on some crazy and interesting works. I graduated from Northwestern University with M.S. in Computer Engineering, supervised by Prof. Manling Li, and collaborated with Prof. Huajie Shao. Previously, I worked in the Machine Vision and Robotics Laboratory at Northeastern University, mentored by Prof. Kechen Song, where I obtained my bachelor's degree in Intelligent Manufacturing Engineering.

📊 Data-Driven Large Scale Training 🌍 World Models with Physical Laws 🤖 Embodied AI

Research Focus

Data Collection & Curation

I believe high-quality, carefully curated data is becoming a foundational advantage for embodied agents.

Physics-Grounded World Models

I am interested in world models that learn through physical-world interaction and reflect the constraints of real-world physics.

Embodied Agents

I aim to develop embodied agents capable of continuous adaptation, self-improvement, and lifelong learning.
