Welcome to Yi’s Homepage!

I am a first-year Ph.D student in the Department of Computer Science at Virginia Tech, fortunately advised by Dr.Xuan Wang. I am also a student member of the Sanghani Center for Artificial Intelligence and Data Analytics at VT. Before that, I received my B.S. in computer science from Wuhan University.

Research Interest

My primary research interests are Graph Data Mining, NLP, and AI for Sciences.
