I am currently a first-year Ph.D. student at Shanghai Jiao Tong University (SJTU), under the supervision of Prof. Cewu Lu and Prof. Yong-Lu Li in the RHOS group at MVIG. Prior to that, I received my Bachelor’s degree from SJTU in 2025.

My research interests lie in understanding and modeling the dynamic 2D and 3D physical world. I am especially interested in robotic scenarios, where perception, interaction, and physical reasoning are tightly coupled.
