About Me

I am a third-year Ph.D. candidate in the Data Science and Analytics Thrust, at The Hong Kong University of Science and Technology (Guangzhou), supervised by Prof. Wei Wang and co-supervised by Prof. Lei Li.

Research Interests

My research focuses on vector databases, particularly vector similarity search. My interests include techniques such as graph-based vector index and vector quantization technology, as well as integrating complex queries with vector databases.
