I am a Ph.D. student at Nanjing University. My research interests include generative world models, controllable video generation, 4D spatial memory, radar simulation, and visual scene understanding.

Before joining Nanjing University, I received my M.S. and B.S. degrees from Beihang University. My previous research covered stereo matching, autonomous driving perception, radar cube simulation, video relighting, and neural rendering.
