I am currently pursuing my Ph.D. in the Department of Computer and Information Sciences (CIS) at the University of Delaware (UD), advised by Xi Peng. Previously I collaborate with Julie Michelle Klinger on designing machine learning frameworks tailored for geospatial data analysis. My research primarily revolves around Computer Vision and Machine Learning. Specifically, I am dedicated to exploring the application of trustworthy deep learning models. Additionally, my research also involves developing frameworks for video learning and understanding.

Prior to joining the University of Delaware, I completed my M.S. degree in the Department of Computer Science at Boston University advised by Margrit Betke. During that period, my research focus was on developing models for text detection and recognition. Before that, I got my B.Eng. degree from the Wuhan University of Technology.

In the industry, I am fortunate to have the opportunities to intern or collaborate with Fan Du (Dolby Laboratories), Ting Liu (Google), Long Zhao (Google), Liangzhe Yuan (Google), R. Manmatha (Amazon), Yusheng Xie (Amazon).
