My research focuses on embodied foundation models for whole-body intelligence through agentic world and action modeling. I develop these models for physical agents, combining learning from human and robot experience with the capabilities of general-purpose large language models and agentic systems. I also build virtual worlds for robot learning and evaluation by combining learned dynamics models with physics-based simulation.

I serve as technical co-lead of the World Model team and technical lead of the Robotics Simulation team at XPENG Robotics.

Previously, I was a postdoctoral research fellow at Nanyang Technological University, Singapore, where I also received my Ph.D., advised by Prof. Guosheng Lin and Prof. Kim-Hui Yap. I interned at ByteDance with Dr. Jiashi Feng.
