Biography

I am a master's student in the School of Computer Science at Fudan University, advised by Prof. Zuxuan Wu.

Research Interests

My research focuses on efficient and controllable video generation, spatiotemporal modeling, and post-training for video generation models. I am particularly interested in video frame interpolation, video motion editing, camera-controllable generation, reinforcement learning, and on-policy distillation.
