Short Biography

I am a Ph.D. student at the school of Data Science and Engineering, East China Normal University, advised by Prof. Peng Cai. I am fortunate to work closely with Prof. Xuan Zhou and Prof. Aoying Zhou. I have a broad interest in many topics of databases, especially AI4DB, which currently focuses on large language models (LLMs) enables database performance optimization (LLM4DB). Prior to that, I worked as a kernel R&D engineer at VMWare Greenplum database team, focused on nested transactions and query optimization. I have published several papers at top international database conferences (CCF-A), such as SIGMOD, VLDB, and ICDE.
