Here is Lei Liu. I am an AI researcher focused on (medical) large language models and applications. I obtained my PhD from The Chinese Univerity of Hong Kong, Shenzhen (CUHK-SZ) then joined Ant Group with the Plan A Award. Now, I am a postdoctoral researcher sponsored by Ant Group and Zhejiang University.

Hiring：The Ant-Med Algorithm Team is recruiting interns and full-time members for large-scale infra, LLM training and medical applications.
