Biography

I am currently an Associate Professor, PhD supervisor at the Complex Laboratory of New Finance and Economics (NiceLab) and School of Computing and Artificial Intelligence, 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 now lead the GeoText group at NiceLab. 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.
