I am an Assistant Professor within the Department of Urban Planning and Design and the director of the Urban Analytics and Interventions Research Lab at the University of Hong Kong. My research interest lies in causal inference in urban interventions’ social and health effects, using natural experiments. Social science researchers often ask questions about cause and effect. In the context of my research, we are talking about “causes” that are built environment interventions via urban planning and design practices, such as street experiments, a new transport infrastructure, urban regeneration programme, and “effects” in individual and public health and social and economic outcomes. Note the growing body of research on social and health effects of built environment is mostly observational studies constrained in their ability to make causal inferences. I use carefully constructed natural experiments that allow credible causal inference of urban interventions. It is interdisciplinary research on urban analytics, empirical social science, and urban studies and planning.

My ongoing research revolves around three main themes: urban redevelopment and social and health impacts of older people; new metro, active travel and wider health effects; street and public space interventions linked with long-term changes. The three research themes cover different types of urban interventions (e.g., complex interventions, short term actions). Most of the research has secured grants. If you are interested in knowing more about my research, please visit the Urban Analytics and Interventions Research Lab (https://www.ulab.hku.hk).

I have a PhD degree in Geoinformation Science from the Inter-Faculty Programme at The Chinese University of Hong Kong (2014). During doctoral research, I received training from exchange programmes within Center for Geographic Analysis at Harvard University and Department of Geography at University of Cambridge. After doctoral training, I had four-year research experiences as a research associate, postdoctoral fellow, and research assistant professor in geography, planning and architecture schools at The Chinese University of Hong Kong, Peking University and The University of Hong Kong.
