About Me

I am currently a Ph.D. student at the School of Electrical Engineering and Computer Science, the University of Queensland, supervised by A/Prof. Guangdong Bai and Dr. Jason Xue. My research focuses on tackling real-world security & privacy issues, especially on building trustworthy AI and designing privacy-preserving systems.

Research Interests

• Trustworthy AI
• Safety of Multimodal Models and Large Language Models
• NSFW Content Generation and Mitigation
• Privacy-Preserving on Purpose Limitation Principle
