Welcome to GeoX Lab!

About me

I am an Assistant Professor in the Department of Land Surveying and Geo-Informatics in The Hong Kong Polytechnic University (PolyU). I received PhD degree in Geo-Informatics from Royal Institute of Technology KTH, Sweden in 2012. Prior to joining PolyU in 2016, I worked as a postdoc at the GIS and GeoCollaboration Lab at Ryerson University, Toronto, Canada.




My research interest focuses on GIScience, transportation geography, and complex network. My research goal is to use state-of-art technologies to advance smart city for a better urban life. I am particularly interested in integrating advances in machine learning into human mobility modeling, human-environment interactions analysis and human behavior analysis across physical and virtual spaces.


GeoX Lab

GeoX Lab aims to develop state-of-art GIScience theories and technologies to advance smart city for a better city life. The rise of Big Data has led to a new paradigm of urban computing and informatics. Our research work focuses on using large databases and geographic information system to build up an urban computing platform to analyze urban performance indexes.
