Prof. Xuejie Ding is an Assistant Professor in the Department of Social Work and Social Administration at The University of Hong Kong (HKU). She hold a DPhil in Sociology from the University of Oxford, and her research lies at the intersection of population health, biodemographic patterns of health, social demography, and the dynamics of work and family. She conducts cross-disciplinary research to uncover how social determinants, biological processes, life course experiences, and environmental contexts intersect to shape and mitigate health inequalities. Her research has been published in high-impact journals such as Nature Human Behaviour, PNAS, BMJ Open, Journal of Epidemiology and Community Health, and Social Science & Medicine. These publications have advanced understanding of how structural inequalities become biologically embedded, how energy and housing deprivation affect public health, and how genetic and environmental factors interact to influence life-course outcomes. Her work has been presented at leading international conferences, and it has informed both scholarly and policy discussions—including contributions to UK governmental advisory reports during the COVID-19 pandemic. Prior to joining HKU, she held research positions at the University of Oxford and the WZB Berlin Social Science Center, and was affiliated with the Leverhulme Centre for Demographic Science and the Pandemic Science Institute. At HKU, she is committed to building an interdisciplinary research program that bridges social science, public health, and policy impact—particularly through work on work–family dynamics, population health and (mental) health outcomes.
