    Research Highlights

    About Me

    Greetings! My name is Dan Xu. I am currently an Assistant Professor in the Department of Computer Science and Engineering at HKUST. I was a Postdoctoral Research Fellow in the Visual Geometry Group (VGG) in the Department of Engineering Science at the University of Oxford, under the supervision of Prof. Andrea Vedaldi and Prof. Andrew Zisserman. I received my Ph.D. in Computer Science from the University of Trento in 2018, under the supervision of Prof. Nicu Sebe in Multimedia and Human Understanding Group (MHUG). I was a student research assistant in MMLab and the Department of Electronic Engineering at The Chinese University of Hong Kong under the supervision of Prof. Xiaogang Wang. My research foucuses on computer vision, multimedia and machine learning. Specifically, I am interested in deep learning, multi-modal and multi-task learning, as well as their applications into 2D/3D perception, understanding, and generation, involving topics such as dense scene prediction (e.g., depths, semantics, objects, and parts), multi-modal multi-task scene perception, open-world understanding, large-scale 3D scene modeling and end-to-end deep visual slam systems, human- and scene-centric 2D/3D generation and editing.
