I am a Research Professor (Zijiang Young Scholar) and Ph.D. Supervisor at the School of Geospatial Artificial Intelligence, East China Normal University (ECNU). My research interests lie in spatial intelligence, 3D vision, point cloud processing. The overarching goal of my research is to enable machines to reliably perceive, understand, and reconstruct complex 3D environments. Before that, I was a Postdoctoral Research Fellow at College of Computing and Data Science, Nanyang Technological University, working with Prof. Ying He. I received my Ph.D. from Sun Yat-sen University in 2023, supervised by Prof. Yulan Guo.
In 2025, I was selected for the Shanghai Overseas High-Level Talent Program (上海市海外高层次人才计划) and Ministry of Education's Overseas Postdoctoral Talent Introduction Program (教育部博士后海外引才专项).
OPENINGS
Ph.D. / Master / RA / Postdoc — I am always looking for self-motivated students, research interns, and researchers to work on 3D vision and spatial intelligence, covering topics such as multi-agent collaborative 3D detection, 3D scene reconstruction and generation.
If interested, send me your resume.
