About Me

I am currently a PhD student in School of Computing and Augmented Intelligence (SCAI) at Arizona State University, advised by Prof. Jin Wang. My research interests include data discovery, data integration, and AI for database systems. I am broadly interested in developing intelligent database systems that leverage modern machine learning and large language models to improve data management and analytics.
