I received my B.S. and Master degrees in Information Engineering at Yangzhou University in 2009 and 2012, respectively. I received my Ph.D. degree in pattern recognition and intelligence system at Nanjing University of Science and Technology with Prof. Huaijiang Sun, in 2017. Currently, I am a Professor in the School of Computer Science at Nanjing University of Information Science and Technology. I am also a member of the Machine Learning and Visual Perception (MLVP) with Prof. Yuhui Zheng.

I have been a visiting student working with Prof. Fatih Porikli at Australian National University (ANU) from Oct. 2015 to Oct. 2016. After 2018, I am a Postdoctoral Researcher at the School of Computer Science and Engineering, Nanyang Technological University (NTU), Singapore, worked with Prof. Weisi Lin.
