I am a master candidate under the supervision of Prof. Yushu Zhang at Nanjing University of Aeronautics and Astronautics (NUAA).

My research focuses on multimedia security and privacy protection.

My current work involves visual content privacy protection through differential privacy and advanced computer vision techniques.
