About me

Hello! I am Mengshi Chen, a third-year Ph.D. student at the Antai College of Economics and Management, Shanghai Jiao Tong University, advised by Prof. Kai Wang. My research interests include databases, deep learning, and graph learning.

My recent work explores language models for tabular data preparation, learned indexes in database systems, and graph learning for financial fraud detection.
