Hi!👋 I’m Yimin, a second-year Computer Science Ph.D. student at the National University of Singapore (NUS🦁), fortunate to be supervised by Prof. Xiao Xiaokui.
Previously, I received my B.Eng. in Computer Science & Engineering with honors from The Chinese University of Hong Kong, Shenzhen (LGU🐲) in 2021, graduating third in my major. Before starting my Ph.D. in 2023, I completed my master’s degree at NUS, where I explored AI-assisted stream processing systems with the TikTok Infra group.
My current research focuses on LLM-assisted data management, information retrieval, and conversational agent systems.
Feel free to drop me an email if you have any questions or opportunities!
