About Me

I am now working as a Pre-tenure Associate Professor at Fudan University with the Research Institute of Intelligent Complex Systems. My current research interests consist of mobile systems and user behavior modeling in online social networks. I am serving as the PI of National Natural Science Foundation of China (No. 62102094).

I received  my PhD degree in Computer Science and graduated from Fudan University with honor in Sep. 2020, co-advised by  Prof. Yang Chen and Prof. Xin Wang. In addition, I have been co-supervised by Prof. Xiaoming Fu at Computer Network Group of the University of Goettingen and have collaborations with Prof. Pan Hui at Hong Kong University of Science and Technology and University of Helsinki.

Before joining the Researh Institute of Intelligent Complex Systems, I worked as a Postdoc Researcher at School of Computer Science, Fudan University (Shanghai Super Postdoc Fellowship), and served as the PI of China Postdoctoral Science Foundation (No. 2021M690667, No. 2022T150130).
