I am a Ph.D. student from the Department of Computer Science and Technology at Tsinghua University. I am supervised by Prof. Zhiyuan Liu and affiliated with the THUNLP Lab. My research interests lie within the intersection of Natural Language Processing and Information Retrieval.

I received my bachelor degree from Tsinghua University in Jun. 2021.

Projects

I’m the project leader and developer of MiniCPM-Embedding, MiniCPM-Reranker, MiniCPM-Embedding-Light, MiniCPM-Reranker-Light, and OpenMatch-v2.
