I am an Assistant Professor in the Department of Urban Planning and Design, Faculty of Architecture at the University of Hong Kong. My research focuses on (1) Transport Infrastructure Development: I use natural experimental studies to investigate the impact of new urban rail transit on urban sustainability and healthy living of mega- and medium-sized cities in China. I am interested in the impact of high-speed railways on regional development and economic performance, with a particular interest in the lagged fortune regions in the belt-and-road initiative; (2) Spatial Data Infrastructure Development: I have a rich experience in constructing fine-scale spatial data infrastructure for smart and healthy city research and application. I led the mapping of a three-dimensional pedestrian network for the high-density city of Hong Kong. Working with Hong Kong governmental sectors, the network is becoming a data infrastructure for the city. I am also interested in constructing regional-scale spatial database and modelling for the environmental and social risk assessment, which will be focused on the belt-and-road economic corridors. I received my PhD in Geoinformation Science and Human Geography from The Chinese University of Hong Kong (2014). After doctoral training, I have four-years research experiences as a research associate, postdoctoral fellow, and research assistant professor.
