About Me

Hello! My name is Zeqin Yu, and I am currently a second-year PhD student at Sun Yat-sen University (Sep. 2023 - Jun. 2027), advised by Prof. Jiangqun Ni. I completed my Master’s degree at Shenzhen University, where I was advised by Prof. Bin Li and worked in the Guangdong Key Laboratory of Intelligent Information Processing and Shenzhen Key Laboratory of Media Security. I obtained my Bachelor’s degree from Shenzhen University as well.

My research interests are primarily focused on multimedia forensics and security, particularly in detecting and preventing manipulation and forgery of images, videos, and other media content. I also have extensive experience in competitions and data creation, particularly with real-world tampered images and videos.

If you are interested in my research or would like to explore collaboration opportunities, feel free to reach out! I am also currently looking for internship or exchange student opportunities!
