I am a PhD student at CVG, ETH Zurich, supervised by Prof. Dr. Marc Pollefeys. I got my Bachelor's and Master's degree from BBNC Lab, Department of Automation, Tsinghua University, supervised by Prof. Dr. Xiangyang Ji. My research interest lies in 3D computer vision, egocentric vision, robotic perception.

Some of my close colllaborators include PD Dr. Federico Tombari, Dr. Francis Engelmann, Dr. Gu Wang, Dr. Fangjinhua Wang, Dr. Xi Wang. I am invited as a reviewer for CVPR, ICCV, ECCV and NeurIPS.
