Minghui Xu   (徐明辉)

In 2021, I joined the School of Computer Science and Technology, Shandong University , where I am also a member of the Institute of Intelligent Computing (IIC). Before that, I completed my PhD in Computer Science at The George Washington University in 2021 (advised by Prof. Xiuzhen Cheng) and my BS degree in Physics at the Beijing Normal University in 2018.
