Zhiwei Liu (刘 志伟)

Currently, I am a 4th year Ph.D. student at Computer Science department of University of Illinois at Chicago. I am advised by Prof. Philip S. Yu in the Big Data and Social Computing Lab.

Before joining UIC, I received B.Eng degree in computer science and technology from Yingcai Honor School of the University of Electronic Science and Technology of China, advised by Prof. Yang Yang.

My research interests lie in data mining and machine learning. Specifically, my research focuses on graph neural networks, recommender systems and fraud detection.
