I am a last-year PhD student in PolyU NLP Group at The Hong Kong Polytechnic University, fortunately advised by Prof. Maggie Wenjie Li.
I am interested in 💡 LLM-based reasoning, 🤖 Conversational AI and 🩺 Medical AI. Recently, I focus on the following topics:
- LLM-based Reasoning;
- Interpretable Medical Dialogue Systems involving diagnosis, prescriptions, concultations, etc. I am committed to enabling machines to function as reliable and trustworthy clinicians;
- Other applications empowered by Large Language Models (LLMs).
🔥 I am available on the job market and actively looking for industry opportunities!
