Biography

I am a first-year Ph.D. student supervised by Prof. Chuanxia Zheng at Physical Vision Group, College of Computing and Data Science (CCDS), Nanyang Technological University (NTU), Singapore. Before that, I was fortunate to intern at Tencent ARC Lab and Shanghai AI Lab, working with Dr. Wenbo Hu, Prof. Jianfei Cai, Prof. Xiaoguang Han, Prof. Bo Dai, Dr. Linning Xu, and Dr. Mulin Yu.

I obtained my Master’s degree from the University of Science and Technology of China (USTC) in 2025, where I was advised by Prof. Yongdong Zhang and Prof. Tianzhu Zhang. Prior to that, I received my B.Eng. degree in Computer Science and Technology from Northwestern Polytechnical University (NWPU) in 2022, under the guidance of Prof. Yuchao Dai.

My research interests lie in 3D Computer Vision, with a particular focus on:

• 3D/4D World Model
• 3D Gaussian Splatting & Neural Rendering
• Monocular Depth Estimation
