I am a first year PhD student of Perception and embodied INtElligence (PINE) Lab at Nanyang Techological University. Before that, I received my Bachelor and Master degree from Shanghai Jiao Tong University (SJTU), ranking top 20%.

I am currently advised by Prof. Ziwei Wang, and working closely with Prof. Yiling Xu and Rui Ye. My research interests lie in embodied ai, world model, media perceptual quality assessment (e.g., 3D point cloud, image) and low-level vision. Specifically, I focus on world model and mobile manipulation.

I am actively seeking opportunities for Research Internship, please feel free to contact me!!!
