Assistant Professor
School of Computer Engineering, Weifang University, Weifang
Office: 7326, Block VII

I am an assistant professor in Vision and Learning Group from School of Computer Engineering at Weifang University. I received my Ph.D degree from the Department of Electronics Engineering at Pusan National University in 2020, advised by Prof. Jae Ho Kim. Before that, I received my B.S. Degree in School of Information Science and Engineering from Shandong University in 2011 and M.S. Degree in School of Electrical and Electronic Engineering from Nanyang Technological University in 2014. My research interests include image processing, computer vision, and deep learning, etc.
