About Me

I am an Associate Professor at the School of Geospatial Engineering and Science and Technology, Sun Yat-Sen University. Before joining SYSU, I was a postdoctoral fellow at the University of Bonn. Before that, I received my Ph.D. and B.S. and worked as a postdoctoral fellow at School of Resource and Environmental Sciences, Wuhan University, supervised by Huanfeng Shen. In my final year of doctoral studies, I was a visiting scholar at the University of Hanover.

My primary research interests lie in the cartography, image processing and pattern recognition.
