Biography

I am a third-year joint Phd student at The Hong Kong Polytechnic University (PolyU) & Southern University of Science and Technology (SUSTech) from 2021, advised by Prof. Maggie, Wenjie Li and Prof. Jiang Liu. I received my Master's degree from China Agricultural University (CAU) in 2020, and Bachelor's degree from Guangdong University of Technology (GDUT) in 2017.

Always open to collaboration. Feel free to drop an email and I'll be happy to have a discussion. 😁

Research

Currently, I am working on Medical Natural Language Processing and Medical Multimodal Learning. Especially, I focus on the following directions:

• Medical Report Generation:
  • Accurate (ORGan@ACL'23) , Precise (Recap@EMNLP'23 Findings) , and Consistent (ICon) Radiology Report Generation;
  • Ophthalmic Report Generation;
• Healthcare Agents: interested in developing healthcare agents that can utilize other medical applications (e.g., medical report generation systems) and provide consultations (DFMed@ACL'23 Findings and IADDx).
