Dr Du is a Postdoctoral Fellow at the Department of Social Work and Social Administration, HKU. Her research focuses on public transport, urban redevelopment, and their health impacts on older people in Hong Kong. She holds a PhD in Urban Planning and Design from The University of Hong Kong, where her work centred on transport and healthy ageing. Prior to her doctoral studies, she gained three years of experience as a research assistant in sociology and housing studies.

She applies mixed qualitative and quantitative methods, including natural experiments, to compare pre- and post-transport intervention changes in older adults’ mobility and health. In-depth interviews are used to understand behavioural adaptation processes and the pathways linking these changes to subjective well-being. Her research provides insights to inform policies that support age-friendly environments and healthy ageing by addressing older adults’ transport needs.
