(also written as Xiang-Yu Guo)

I am a PhD student (2017.8 -- now) at the Department of Computer Science and Engineering of SUNY Buffalo, and I am very fortunate to be advised by Prof. Shi Li.

Before coming to the United States, I obtained my bachelor degree (2014) in Electronic Engineering from Xidian University, and master degree (2017) in Computer Science from Nanjing University under the supervision of Prof. Wei Wang.
