The Making of Hong Kong:
3D pedestrian network as the critical walking infrastructure
The three-dimensional pedestrian network, enabling multi-level city living in a vertical metropolis, is a fundamental consideration in urban planning and design practices for high-density cities.

"My research interests focus on public transport and urban redevelopment and their health impact on older people in Hong Kong. Before starting a doctoral degree, I had three-year working experience as a research assistant in sociology and housing studies."
Current Research
Yao's thesis investigates causal links between public transport changes and older adults' travel behavior, social engagement, and well-being. Older people face mobility challenges, so transport modifications can impact accessibility, social connections, and well-being. She explores how interventions shape travel adaptation and how psycho-social and environmental factors mediate behavior change impacting well-being.
She applies mixed qualitative/quantitative methods using a natural experiment to compare pre/post-transport intervention differences in older adults' mobility and health. In-depth interviews aid in understanding the behavior adaptation process and pathways from changes to subjective well-being. Findings can help policy support age-friendly, healthy aging by supporting older adults' transport needs.
