I am an assistant professor at Hunan University. I received my Ph.D. degree from Tsinghua University, advised by Prof. Shixia Liu. Before that, I received my B.S. in Electronic Engineering from University of Science and Technology of China. My research interest focuses on visual analytics and machine learning, especially visual analysis methods to improve training data quality.
