Short Bio

I am a first-year Master’s student at the School of Electronic and Computer Engineering, Peking University , advised by Prof. Li Yuan and Prof. Yonghong Tian . I am also fortunate to work closely with Prof. Daquan Zhou. I received my B.E. degree from the University of Chinese Academy of Sciences (UCAS) in 2025, where I was awarded as an Outstanding Graduate.

My research interests primarily lie in video generation for real-world applications.

Omni-Grid: Taming Image-based Unified Multimodal Models to Video

Juncheng Ma, Yuelin Li, Yufan Deng, Zhenyu Tang, Dongdong Yu, Li Yuan, Changhu Wang, Daquan Zhou†, Yonghong Tian†

Under Review

We present a cost-efficient approach to adapt image-based UMMs to the video domain while preserving their original strengths. Our model surpasses previous video-based UMMs on VBench, while also exhibiting zero-shot multimodal interleaved abilities in video, including CoT reasoning and text rendering.

FastAvatar: Accelerating Portrait Animation via Memory-Adaptive Caching

Juncheng Ma, Yuxuan Du, Yanan SUN, Zhening Xing, Changlin Li, Zhenyu Tang, Bo Li, Peng-Tao Jiang, Li Yuan, Daquan Zhou†, Yonghong Tian†

Under Review

We proposed SyncCache, a training-free, audio-aware, and memory-adaptive caching strategy tailored for audio-driven portrait animation, which delivers a 4.12× acceleration on Hunyuan-Avatar and 3.75× on Wan-S2V with negligible degradation in visual quality or audio alignment.
