I am currently on the job market and actively looking for industry opportunities. 🚀🚀🚀

I am a final-year joint Ph.D. student, advised by Prof. Maggie, Wenjie Li@NLP Group, PolyU and Prof. Jiang Liu@iMED Shenzhen, SUSTech. 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.

News

[Sep. 2024] 🔥 ICon is accepted by EMNLP 2024 Findings.

Research

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

• Medical Report Generation: Accurate (ORGan@ACL'23) , Precise (Recap@EMNLP'23 Findings) , and Consistent (ICon@EMNLP'24 Findings) Radiology Report Generation;
• Medical VQA
• 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, Emulation@ACL'24 Findings and IADDx).

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