😊 About me
I am a Ph.D. student in Cyber Security at Jinan University, supervised by Prof. Tianlong Gu, affiliated with the Engineering Research Center of Trustworthy Artificial Intelligence (Ministry of Education). I am currently a visiting student at Nanyang Technological University (NTU), sponsored by the China Scholarship Council (CSC), and am fortunate to be advised by Prof. Bo An (AAAI Fellow) and Assoc. Prof. Nicolas Vun Chan Hua.
Research interests: Trustworthy AI, with a focus on AI Safety, Content Moderation, and Fairness. I am also interested in multimodal learning and recommender systems, and have collaborated with other researchers on related topics.
I collaborate with Dr. Shuai Zhao on AI safety and trustworthy large language models, and with Dr. Yanhao Jia on multimodal bias.
My research aims to understand and enhance the capabilities of next-generation general AI systems in real-world applications.
