Weirong Chen
Hi! I am a second-year PhD student at Technical University of Munich and University of Oxford under ELLIS,
supervised by Prof. Daniel Cremers and Prof. Andrea Vedaldi.
Previously, I received my Master's degree in Computer Science from ETH Zurich advised by Prof. Marc Pollefeys.
I worked on 3D vision projects at Microsoft Mixed Reality & AI Lab Zurich, Computer Vision and Geometry Group (CVG), and Computer Vision Lab (CVL).
Before this, I obtained my Bachelor's degree in Computer Science from The Chinese University of Hong Kong
and interned at SenseTime Research.
My research interests lie in the interplay between computer vision and 3D geometry, with a focus on visual localization, 3D/4D reconstruction, and neural scene representations.
I am also broadly interested in object-level perception, egocentric vision, and spatial computing.
