Biography

I am a year four PhD student in Computer Science at the University of Macau, advised by Prof. Derek F. Wong at the NLP2CT Lab. My research focuses on Personalized Large Language Models, LLM Agents, and Multi-Modal RAG systems. I serve as a reviewer for ACL and EMNLP. I’m particularly interested in building AI systems that can better understand individual users and deliver more helpful responses. Beyond research, I enjoy building practical applications. I actively participate in competitions and algorithm challenges to test new ideas. I’ve developed smart education platforms and automated travel planning tools that demonstrate how research can make a real difference. Check out my AI applications to see how I turn research into tools that solve real problems.
