About me

I joined Beijing University of Technology (BJUT) in 2015.7, where I am now an associate professor. Before BJUT, I worked at Chinese Aeronautical Establishment from 2012.1 to 2015.6 as a Computer Scientist. I received Ph.D. (2012.1) in Computer Vision at Beijing University of Posts and Telecommunications. During 2008 to 2010 and 2018 to 2019, supported by China Scholarship Council (CSC), I had the opportunity of working as a visiting Ph.D. and visiting scholar respectively in the Department of Computer Science and GRASP Laboratory at University of Pennsylvania (UPENN), USA.

Research Interests

My research interests are computer vision such as video understanding, 3D object detection, object tracking, video recommendation system and other related fields, especially focus on weakly or unsupervised methods.
