About me

I'm currently an assistant professor at School of Computer Science (School of Cyber Science and Engineering), Shanghai Jiao Tong University (SJTU).
I am also a member of the AI&Cognition Security Lab, working closely with Prof. Xinghao Jiang and Tanfeng Sun.

Before joining SJTU, I worked closely with IEEE Fellow Prof. Hong Yan and Min Xie as a postdoctoral research fellow at the City University of Hong Kong (CityU-HK) from 2021.12 to 2024.02. I was also an associate researcher at the City University of Hong Kong-Shenzhen Research Institute in 2021, and a visiting Ph.D. student with the Rapid Rich Object Search Lab (ROSE) led by IEEE Fellow Prof. Alex C. Kot, Nanyang Technological University, Singapore. I received a Ph.D. degree in Cybersecurity from Shanghai Jiao Tong University (2021), and was awarded as the outstanding graduate of SJTU. Prior to that, I studied at State Key Laboratory of Information Engineering in Surveying, Mapping, and Remote Sensing, Wuhan University, Hubei-Wuhan, China.

As a researcher in the field of multimedia forensics and security, my research is related to AI-Generated Content Detection\Fake Image&Video Detection\Image&Video Forgery Detection\Deep learning\Machine Learning, etc. I am committed to leveraging advanced technologies to address real-world multimedia information security challenges.

Recruitment: Pleased to announce that I have 2-3 Master's positions available for the academic year starting in 2026. Besides, I am actively looking for interns/engineers/visitors with CV/ML/Cybersecurity background to work together on various multimedia security topics. If you share same/similar interests, pls feel free to drop me an email with your resume, publications (if any), and a brief statement of interest.
