Introduction
I am an Associate Professor in Urban Planning and Design with extensive international experience. My research integrates quantitative, qualitative, and spatial analyses to examine urban policy, mobility, housing, and social equity. I blend STEM methods with social science insights to inform sustainable, inclusive urban development and public policy. I have published widely and collaborated across China, South Korea, and the U.S.

Modern streetview image data provide two types of valuable information: the objective built environment and humans' subjective perception of the streetscape. In the road safety domain, the built environment has been identified as playing a significant role while indicators of human perception are commonly used to evaluate street quality in urban pl...
This study examines the transformation of urban air transportation in Chengdu before and after the opening of Tianfu International Airport, with a focus on the impact of a multi-airport system (MAS) on low-cost carriers (LCCs) and full-service carriers (FSCs) in megacities. Using actual operational data, this study systematically analyzes the chang...
The 15-minute community life circle (15-min CLC) concept focuses on providing accessible services for older adults within a short walking distance. However, few studies have developed a comprehensive evaluation system of 15-min CLC walking accessibility for older people, and little is known about the effects of street-level environment characterist...
Recent urban studies have highlighted the significant role of education in the underlying dynamics of urban segregation, particularly residential segregation. In China, residence-based education policy links school enrollment to place of residence, driving up housing prices in desirable school districts and inducing residential segregation. However...
This study investigates the impact of a newly implemented public transport interchange discount policy in Suzhou, China, focusing on its effects on metro-to-bus interchange behaviors across various spatial and temporal dimensions. Utilizing two distinct datasets spanning periods before and after the policy's implementation, a comprehensive spatial-...
To effectively capture and explain complex, nonlinear relationships within bicycle crash frequency data and account for unobserved heterogeneity simultaneously, this study proposes a new hybrid framework that combines the Random Forest-based SHapley Additive exPlanations (RF-SHAP) method with a random parameter negative binomial regression model (R...
Our study presents fresh insight into the impacts of air-related information accessibility and policy awareness on citizen’s life satisfaction, through the lens of perceived air pollution sources. It is widely accepted that disclosing information about air pollution adversely affects an individual’s life satisfaction. However, the impact of informa...
This study employs the stated preference method to explore airline passengers' choices during security screening and examines their trade-offs between privacy and efficiency. We compare two Asian economic hub cities (i.e. Hong Kong and Shanghai), with 500 business and leisure travellers sampled from each city. A generalised mixed multinomial logit...
The so-called "Corona Blue" decline in mental health after the COVID-19 outbreak. This study examines how COVID-19 risk perception affects mental health via urban space usage in Seoul, Korea, and Shanghai, China. It uniquely explores direct PR-MH and OS-MH effects, along with indirect effects mediated by pandemic-driven changes in urban space utili...
The COVID-19 pandemic has brought about significant social changes through government prevention andcontrol measures, changes in people’s risk perceptions, and lifestyle changes. In response, urban inhabitantschanged their behaviors significantly, including their preferences for transportation modes and urban spaces inresponse to government quarant...
This comparative study examines the shifts in perception and behavior among urban residents in Seoul and Shanghai during the COVID-19 pandemic. The findings reveal significant disparities in perception and behavior between the cities and variations within each city at different stages of the pandemic. Shanghai residents had a higher perception of t...
The COVID-19 pandemic has hit the world and made significant impacts on all parts of human settlement areas. Passenger journeys on public transportation have dropped significantly. This study looks at the effects of the COVID-19 on the change of bike usage-subway ridership integration between 2019 and 2020 in New York City (NYC), USA. To investigat...
The development of city transportation often promotes prosperity in urban economies, but it can also cause safety issues that adversely affect local residents. It is widely acknowledged that the built environment has a significant impact on traffic accidents. Many studies have shown a link between different land use characteristics and accidents, a...
In recent years, many cities have implemented bike-sharing programs (BSP) to improve the travel efficiency of short trips. Early studies have analyzed how built environment factors affected bike-sharing usage. However, these studies mainly used global regression models that cannot demonstrate the spatial variation relationship between the built env...
In cities, road traffic accidents are critical endangerment to people’s safety. A vast number of studies which are designed to understand these accidents’ leading causes and mechanisms exist. The widely held view is that emerging analysis methods can be a critical tool for understanding the complex interactions between land use and urban transporta...
This paper explores door-to-door commuting pa erns and the way commuting time is associated with three factors: the built environment, transport mode (from residence and workplace to HSR stations), and commute frequency. Econometric and statistical analyses are employed to examine evidence from China that draws on a survey targeting Suzhou-based HS...
In recent years, many cities around the world have implemented bike-sharing programs. A number of studies on the relationship between the built environment and bike usage have provided important insights into understanding bike-sharing systems. However, the effects of the built environment on the structural properties of bike-sharing networks are s...
Each year, thousands of units are lost from the assisted rental housing inventory through deterioration and default, subsidy expiration, and market-rate conversion. While a good deal of research and data collection has focused on identifying at-risk developments, less is known about what happens to former assisted developments after they exit incom...
This study explores how the locations and characteristics of neighborhoods affected the process of housing filtering in the Orlando metropolitan area during the 2000s. The results show that racial composition was an important determinant of filtering down and that the foreclosure rate and income composition of neighborhoods became more important fa...
This study analyzes the effects of impact fees on urban form and congestion through econometric analysis. The results show that there is some evidence that impact fees might reduce congestion by creating disincentives to residential development and job creation. However, direct evidence of a negative effect of impact fees in development and job gro...
