Sun, Guibo

I am a Research Assistant Professor in the Faculty of Architecture at the University of Hong Kong. My research focuses on the relationships between built environment and health. My recent work includes a series of studies on the integration of urban rail transit and walking environment in Chinese cities. I am also working on the measurement of high-dense built environment in Hong Kong for health studies. My current NSFC project is a ‘natural experiment’ of urban rail infrastructure and active travel in Nanchang, which is a medium-sized city of China. I received my Ph.D. in Geoinformation Science from The Chinese University of Hong Kong (2014).
