😊 About me

I am a Ph.D. student in Cyber Security at Jinan University, under the primary supervision of Prof. Tianlong Gu. 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 and Assoc. Prof. Nicolas Vun Chan Hua​. My research interests:

  • AI Safety
  • Content Moderation
  • Fairness
  • Recommender System

My research aims to understand and enhance the capabilities of next-generation general AI systems in real-world applications. Specifically, my work focuses on fairness in large language models and multimodal recommender systems, addressing algorithmic bias, representation disparities, and safety issues to build trustworthy and equitable AI technologies.
