I am a first-year Ph.D. student from MMLab, The Chinese University of Hong Kong, and my advisor is Prof. Tianfan Xue. I received both my Bachelor's and Master's degrees from Beijing Institute of Technology, supervised by Prof. Jianan Li. I spent a wonderful time in Qcraft and SenseTime as a research intern, mentored by Boyin Zhang and Dr. Zhanpeng Huang, respectively.

My current research interest lies in 3D vision, especially for high-quality, scalable 3D Generation with Diffusion Model and NeRF.

My previous work mainly focused on 3D perception on Point Clouds. I have also been working on NeRF and Diffusion Model for 3D generation. (*: Equal Contribution †: Corresponding Author)

We establish new lidar-scanned scene flow datasets and propose a fast and hierarchical network for real-world scene flow estimation.

We propose a novel class-aware 3D proposal generation strategy and an efficient fully sparse convolutional 3D refinement module for vote-based Indoor 3D Detection.

We propose the first powerful 3D window-based transformer backbone on sparse 3D voxels leveraging mixed-scale information.

We propose a novel multi-modality two-stage approach to effectively and efficiently fuse point clouds and camera images in the Regions of Interest(RoI).

The dynamic graph constructing strategy can well capture the fine-grained geometry ignored by previous aggregation operations.
