About

I am currently a second-year Ph.D. student in the College of Computer Science and Technology at Zhejiang University. My research interests include high-dimensional data storage, retrieval, and their applications in large language models (LLMs).

My current research focuses on the following topics:

  • Graph-based vector indexing and retrieval algorithms
  • Complex query processing in high-dimensional data
  • Vector database and its applications in large language models
