About me

I am a second-year Ph.D. student in Computer Science at the University of Massachusetts Amherst (UMass), advised by Prof. Alexandra Meliou. Before joining UMass, I earned my B.Eng. degree in Computer Science and Engineering from the Southern University of Science and Technology (SUSTech) in 2024.

My research interest focuses on database systems and large-scale data processing, with an emphasis on performance optimization for vector data.
