I am a final year Master student at BBNC Lab, Department of Automation, Tsinghua University, supervised by Prof. Dr. Xiangyang Ji. I got my bachelor's degree also from Department of Automation, Tsinghua University. I'm a incoming PhD student at CVG, ETH Zurich, supervised by Prof. Dr. Marc Pollefeys.

My research interest lies in 3D computer vision, especially scene reconstruction and understanding, human-scene interaction and pose estimation.

Some of my close colllaborators include PD Dr. Federico Tombari, Dr. Francis Engelmann, Dr. Yan Di, Dr. Gu Wang, Fangjinhua Wang and Ruida Zhang.

I am invited as a reviewer for CVPR, ICCV and ECCV. I'm a student member of Chinese Society of Image and Graphics (CSIG).

Miscellaneous

I love sports. I enjoy playing soccer⚽ and badminton🏸, etc. and serve as a winger of soccer team of DA, THU. I'm a soccer fans of Man. Utd. and José Mourinho.

I'm also interested in writing novels and poems. Some of my works are published on Chinese literary magazines. My Wechat official account is named "了妄", where I share some literary works I wrote.

I'm a guitar player admiring Tommy Emmanuel and Kotaro Oshio. Meanwhile, I'm a figure skating fans of Yuzuru Hanyu.
