About me

I’m currently a Ph.D. candidate (2020 Fall - Now) in Computer Science and Engineering at the University of Notre Dame, advised by Prof. Fanny Ye. Before that, I received my M.S. degree from The Ohio State University, advised by Prof. Ping Zhang, and my B.S. degree from Xidian University.

My research field lies in graph machine learning and its application. Specifically, I enjoy doing research on semi-supervised and self-supervised representation learning via graph neural networks.
