I am currently a Third Year Ph.D. Candidate at NESA Lab, advised by Prof. Shouling Ji. I received my B.S. degree with honors in Computer Science from Ningbo University (Yangming Class), advised by Prof. Diqun Yan. My research focuses on Trustworthy Generative AI in real-world applications, especially AI Security, AI Copyright Protection, and Privacy-Preserving AI. My long-term goal is to strengthen the source governance of AI technology and rectify illegal AI applications. Recently, I have been focusing more on the Security and Privacy risks of MLLMs and T2I models. Looking for undergraduate or graduate students with common research interests to collaborate with. Feel free to contact me by email or scan my WeChat QR code.
