I am looking for new MS/BS students to join my research project working on machine learning and computer vision. If you have a solid mathematical & English background and happen to be interested in my research, please contact me!


I obtained my PhD degree from Tianjin University in 2016. From Sep 2014-Sep 2015, I was a visiting student in University of Wollongong, Australia, supervised by Wanqing Li. My recent research interests lie in the areas of computer vision and machine learning. I am recently interested in building machine larning models for solving computer vision problems.
