I am now an associate professor in School of Information Engineering, Zhengzhou University. I obtained my Ph.D degree in Department of Computer Science from Hong Kong Baptist University (HKBU, 香港浸会大学) in 2015, supervised by Prof. Jianliang Xu. I was a member of Database Group at HKBU and was presented ACM China Doctoral Dissertation Award Chapter Winner at ACM Turing 50th Celebration Conference - China in 2017.
My research interests span the broad area of location-aware problems with particular focus on location-based services, geo-social computing, and mobile data management. I have published more than 20 technical papers, including IEEE-TKDE, IEEE-TSC, IEEE-TMM, ACM-TIST, ACM-TWEB, DKE, IEEE-ICDE, PVLDB, WWW, ACM-CIKM. I have served as servral program committee members for IEEE-CPSNA, IEEE-BigData, APWEB-WAIM, and a program committee co-chair for IEEE-MUST2019 in conjunction with IEEE-MDM2019.
