Mufei Li (李牧非)'s Homepage

I’m a second-year PhD student in machine learning at Georgia Institute of Technology, advised by Prof. Pan Li. My current research interests include retrieval-augmented generation (RAG) and graph generative models.

Prior to that, I was a software development engineer (SDE) at Amazon Web Services (AWS) Shanghai AI Lab. I received my bachelor’s degree in Honors Math from NYU Shanghai.
