About Me

I’m Runlin Lei (雷润林), a third-year Ph.D. student at Renmin University of China, advised by Prof. Zhewei Wei. My research interests primary focus on graph machine learning.

Before my Ph.D. journey, I obtained my Bachelor’s degree from Shanghai University of Finance and Economics, advised by Prof. Hongsong Yuan and Prof. Hua Liu.
