I am a postdoctoral research fellow at School of Computing and Data Science and Institute of Data Science, The University of Hong Kong, working with Prof. Yanchao Yang and Prof. Yi Ma. My research interests span the interdisciplinary fields of computer vision, graphics, and robotics. Specifically, I focus on 3D reconstruction and generation from images to advance 3D foundation models and embodied AI.
I received my PhD in computer science at Shandong University, supervised by Prof. Baoquan Chen. During my PhD, I was a visiting researcher at ETH Zurich, advised by Prof. Marc Pollefeys. I spent a happy time as a visiting PhD student at Peking University, where I also remotely collaborated with Prof. Leonidas J. Guibas and Prof. Thomas Funkhouser. Before that, I was a research intern at Beijing Film Academy, working with Prof. Kai Xu and Prof. Baoquan Chen.
