About Me

I am an undergraduate student at Yuanpei College, Peking University (PKU), supervised by Prof. Wenzheng Chen at the Visual Computing and Learning (VCL) Lab. I am also privileged to work closely with Prof. Yixin Zhu at Peking University and Kaichen Zhou at Massachusetts Institute of Technology.

My research centers on closing the Real-Sim-Real loop for robot learning — capturing real-world environments into high-fidelity digital twins, training generalizable policies at scale in simulation, and deploying back to the physical world. I’m always open to research discussions and collaboration. Feel free to reach out via changxinhai@pku.edu.cn or WeChat.

Research Interests

I work on the Real-Sim-Real loop for embodied AI, spanning 3D vision and robot learning.

  • 3D Vision: High-fidelity reconstruction, 3D generation, digital twins, and scene understanding.
  • Embodied AI: Simulation, world models, mobile manipulation, and sim-to-real transfer.
