I am a postdoctoral research fellow at HKU School of Computing and Data Science (HKUCDS) and HKU Musketeers Foundation Institute of Data Science (HKU IDS), working with Prof. Yanchao Yang and Prof. Yi Ma. My research interests span across the interdisciplinary fields of computer vision, graphics, and robotics. Specifically, I focus on 3D reconstruction and generation from images to support the development of 3D foundation models and embodied AI.
I received my PhD in computer science at Interdisciplinary Research Center (IRC), Shandong University, supervised by Prof. Baoquan Chen. During my PhD, I was a visiting researcher in the Computer Vision and Geometry Group (CVG), ETH Zurich, advised by Prof. Marc Pollefeys. I spent most of my research time in the Visual Computing and Learning Lab (VCL), Peking University, where I also remotely collaborated with Prof. Leonidas J. Guibas and Prof. Thomas Funkhouser. Before that, I was a research intern in the Advanced Innovation Center for Future Visual Entertainment (AICFVE), in Beijing Film Academy, in collaboration with Prof. Kai Xu.
