I am currently a Postdoctoral Researcher at Spatial Intelligence and Robotics Lab, Westlake University, led by Prof. Peidong Liu (刘沛东). Before that, I worked at City Brain Lab, Alibaba DAMO Academy as a Senior Algorithm Engineer. I obtained my B.S. degree from Harbin Institute of Technology in 2017, and obtained my Ph.D. degree from Zhejiang University in 2022. My doctoral advisor is Prof. Haibin Shen (沈海斌). My research focuses on Spatial Intelligence, especially 3D-Grounded Representation, World Model, and World Action Model. I have published papers in top-tier venues such as CVPR, NeurIPS, AAAI, ACM MM, TMM, and TCSVT. 🔥 I am looking for research or industry positions in the field of Spatial Intelligence, especially in areas related to World Models, World Action Models and 3D AIGC.
