Research Interests

Diffusion Model Architecture: Reimagine diffusion training as a multi-task learning, and introduce how to synergize the training of multiple denoising tasks. [ICLR’24] [ECCV’24] [AAAI’25]
3D/4D Generation: Create high-quality 3D/4D objects and scenes by using generative models such as GAN, diffusion, and RF models, and lifting them into neural scene representations, such as point clouds, NeRF, and 3DGS. [TPAMI’24] [CVPR’24] [CVPR’25] [ICCV’25a] [ICCV’25b]
Video Generation/Understanding: Recently, I am working on various applications in video generation and understandings, including controllable video generation and scalable VideoLLMs. [CVPR’26a] [CVPR’26b]
