I am a third-year PhD student in PolyU NLP Group at The Hong Kong Polytechnic University, fortunately advised by Prof. Maggie Wenjie Li.

I am interested in 🤖 Conversational AI and 🩺 Clinical Natural Language Processing (Clinical NLP). Recently, I focus on the following topics:

• Interpretable Medical Dialogue Systems involving diagnosis, prescriptions, concultations, etc. I am committed to enabling machines to function as reliable and trustworthy clinicians;
• Radiology Report Generation;
• Other applications empowered by Large Language Models (LLMs). My focus lies on reasoning and alignment.
