Dr. Hanzhang Xu, PhD, RN, CNE, FAAN, is an Associate Professor at the Duke University School of Nursing with joint appointments at the Duke University School of Medicine in the Department of Family Medicine and Community Health and the Duke-NUS Medical School in the Health Services & Systems Research Signature Program. She also serves as a Senior Fellow at Duke’s Center for the Study of Aging and Human Development and as a Faculty Affiliate at the Duke Global Health Institute.
As a clinician scientist, Dr. Xu’s research and scholarship center around social determinants of health and disparities in health care and outcomes in diverse older adult populations, with a particular focus on cardiovascular and brain health. Her current program of research falls under two themes: (i) health disparities in a multinational context, with a particular focus on the cognitive function and dementia care among older adults; and (ii) the integration of patient-reported social factors in cardiovascular outcome research.
She has led several research projects funded by the National Institutes of Health (NIH) that leverage the strengths of big data repositories such as electronic health records (EHR), Medicare claims, national survey data and disease registries to improve the cardiovascular and brain health of older adults, with a total award amount being over $5 million. Her work in these areas has been widely cited by researchers in at least 53 countries across 6 continents, and has been featured in international media outlets, including in Yahoo!, TIME, Forbes, and the Mirror.
Dr. Xu is a Fellow of the American Academy of Nursing and was inducted into Sigma Theta Tau International Honor Society of Nursing. She serves on the Editorial Board of the Journal of Aging and Health.

John S. Ji, PhD

Adjunct Associate Professor of Global Health, Duke Kunshan University

John Ji is an Associate Professor at Tsinghua University’s Vanke School of Public Health, doctoral student advisor, and Adjunct Associate Professor at Duke Kunshan University Global Health Research Center. Previously, John was an Assistant Professor and Director of Graduate Studies in the iMEP program at Duke Kunshan University, with a secondary appointment at Duke University’s Nicholas School of the Environment. John received his BA in Neuroscience from Johns Hopkins University and an ScM in Epidemiology and ScD in Environmental Health from Harvard School of Public Health. John teaches a required course on research methods. He launched the first planetary health course at DKU.

John’s research in environmental epidemiology employs population studies to examine the impact of climate and environmental risk factors on health. Specifically, John focuses on how living environments can extend life expectancy and health span, with a particular interest in the effects of green spaces on life expectancy, the modification of air pollution impacts through the interaction of plant-based diets and built environment green spaces, and the development of health-oriented early warning systems for heatwaves. His research found functional aging as a critical climate-sensitive risk factor in the aging population, complementing traditional disease-oriented methods and enhancing adaptation and resilience in cities and communities.

John has authored over 150 peer-reviewed journal articles, featured in high-impact publications such as Environmental Health Perspectives, The Lancet Planetary Health, International Journal of Epidemiology, and Nature Medicine. Stanford/Elsevier lists him among the top 2% of scientists. He led a Lancet series on climate change and health adaptation in the Western Pacific region, published in The Lancet Regional Health – Western Pacific, aiming to shape local policies to enhance climate resilience and adaptation strategies.

John is an Associate Editor for The BMJ, leading a collection on large-scale cohort studies focused on shaping the future of epidemiological research in China. He is also a member of the Advisory Board for The Lancet Regional Health – Western Pacific, and formerly Senior Editor at The Lancet weekly journal. In addition to his editorial responsibilities, John is a councilor for the International Society of Environmental Epidemiology (ISEE) Asia Western Pacific Chapter and a member of the World Health Organization (WHO) Technical Advisory Group (TAG) on Climate Health Ethics.
