I’m a PhD candidate in Computer Science and Engineering at the Hong Kong University of Science and Technology, supervised by Prof. Tristan Braud. I am fortunate to visit the Active Vision Laboratory, University of Oxford advised by Prof. Victor Prisacariu. I received my bachelor’s degree from Shanghai Jiao Tong University. Research Focus: Improve the user’s Augmented Reality (AR) and Virtual Reality (VR) experience and explore the application of AR and VR technology in visualization.
