Biography

I received my Ph.D. in the Robotics Institute, Department of Electrical and Computer Engineering, The Hong Kong University of Science and Technology in 2017. Before that I obtained the B. Eng. degree from South China University of Technology in 2012.

I am a member of Multimedia Technology Research Center (MTrec) in my first two-year postgraduate study, supervised by Prof. Oscar C. Au (IEEE Fellow). I worked on image processing, video coding, and signal processing during this period. After that, I joined the Robotics Institute (RI). My supervisor is Prof. Shaojie Shen. I am working on visual odometry, mapping, 3D reconstruction, visual-inertial fusion, SLAM, and autonomous navigation.

[News] I am now a senior researcher in AI Lab@TencentA few intern positions are available for talented Ph.D. and Master students. Please contact me if you are interested and self-motivated to do cutting-edge work.
