I am a third-year Ph.D. candidate at the School of Computer Science, Fudan University (FDU) and Shanghai AI Laboratory, Shanghai, China. I'm foutunate to be advised by Prof. Xuelong Li and be part of the IPEC@Team. My research focuses on Embodied AI and 3D Computer Vision, with a long-term vision of achieving L2-level Physical Intelligence. I'm excited about the prospect of an "GPT moment" in Embodied AI, where AI systems can learn to interact with the physical world in a more human-like way.

I was a research intern at Shanghai AI Laboratory with Prof. Xuelong Li. In Dec 2024, I secured the National Natural Science Foundation of China (NSFC) grant to support my research.

I will finish my PhD in fall 2027, and I am actively looking for research internship or exciting startup opportunities.
