Biography

I am currently an Associate Professor, PhD supervisor at the Complex Laboratory of New Finance and Economics (NiceLab), School of Computing and Artificial Intelligence, and Research Institute for Digital Economy and Interdisciplinary Sciences, Southwestern University of Finance and Economics (SWUFE). I (supervised by Prof. Fengli Zhang and Prof. Fan Zhou) received the Ph.D. degree in Software Engineering from University of Electronic Science and Technology of China (UESTC), Chengdu, China. I was a visiting scholar, supervised by Prof. Diego Klabjan and Prof. Goce Trajchevski, at Northwestern University from 2019 to 2020.

I am now leading the Geospatial Intelligence and Social Computing (GeoSoc) group at NiceLab. And I also serve as one of the team leaders at The Research Team of Trustworthy Artificial Intelligence R&D and Application. Broadly, my research focuses on Deep Learning+Mobility Mining (e.g., spatio-temporal data processing and location-based services (LBS)). Additionally, I am also partly interested in Regional/Urban Economics in Social Computing. Our research group has established deep collaborations with several universities both domestically and internationally, including Iowa State University, University of Maryland, Delft University of Technology, Vrije University Amsterdam, and etc.
