I am currently a first-year PhD student in Computer Science at the Georgia Institute of Technology, advised by Prof. Kexin Rong. Previously, I earned my B.Eng. in Computer Science and Technology from Shanghai Jiao Tong University (SJTU) in 2024, where I had the privilege of working with Prof. Shixuan Sun. I am broadly interested in the intersection of databases and machine learning, particularly how large language models can be used for data-centric tasks.
