His research areas cover big data and urban planning, sustainable transportation, economic development policy, housing and land use policy, and migration and employment. His publications have appeared in leading journals, e.g., Landscape and Urban Planning, Transportation Research Part D, Cities, and Journal of Cleaner Production. His research has been cited frequently in well-known scientific media, e.g., the Wall Street Journal, Slate Magazine, and CityLab. In recent years, he obtained more than HK$3,800,000 in research grants from government agencies. He was the winner of the 5th Charles M. Tiebout Prize in Regional Science in 2011 and the Regional Science Springer Prize in 2014. Currently, he is an associate editor of The Journal of Urban Management and a special issue co-editor of Transportation Research Part D. dense neighborhoods. Hong Kong should avoid further concentration of employment in/around traditional highdensity downtown areas. Instead, it should promote industrial and commercial activities in newly developed peripheral areas, such as Lantau Island, Sheung Shui, and Sai Kung. Decentralization of employment not only could reduce commute distance and time for residents living in remote areas but also could distribute traffic loads more evenly across the city and relieve traffic congestion in dense areas. 2. Further strengthening the rail system Hong Kong residents heavily rely on public transit, especially rails. The rail system substantially reduces commute time for long-distance trips. Facilities located near rail stations also enhance the capacity of other public transit services. Therefore, Hong Kong could utilize the rail network as the backbone of future public transit development. 3. Allocating more land around rail stations for residential use Residents living around rail stations can access rail transit more easily and benefit from public transit hubs built near the rail stations. Therefore, more land around rail stations should be allocated to residential use. Moreover, the proportion of commercial use around rail stations should be reduced because commercial development forces residents to live farther away from public transit facilities. 4. An optimal built environment depends on transit modes and neighborhood characteristics This study reveals the heterogeneous impacts of the built environment on job accesibility for residents using various transit modes and living in various neighborhoods around the city. It is crucial for urban planners to understand the unique characteristics of neighborhoods and the specific needs of commuters if they wish to enhance job accessibility through optimizing the built environment.
