Biography

I am an Associate Professor at the School of Computer Science and Technology, University of Science and Technology of China (USTC), and a member of the BASE Group of the Anhui Province Key Laboratory of Big Data Analysis and Application.  
I received my Ph.D. in Applied Computer Technology from the Unversity of Science and Technology of China in July, 2020, co-supervised by Prof. Enhong Chen and Prof. Qi Liu, and received my Bachelor degree in Software Engineering from Shandong University in July, 2014.
In 2018-2019, I visited the TIMAN Group at the University of Illinois at Urbana-Champaign (UIUC), working with Prof. Chengxiang Zhai.

Research Interests

My general research interests include Data Mining and Knowledge Discovery, Artificial Intelligence. The main goal is to study how to learn, analyze and organize knowledge from data, as well as designing intelligent systems to help people manage and apply big data and knowledge for improving the service of real-world applications.
