Ph.D. (Epidemiology): National University of Singapore (Oct 2015)
Dr. Dai-Keller is a Lecturer at the School of Population Health. Her research and teaching focus on chronic disease prevention, food policy, research integrity, and health disparities.
As a nutritional epidemiologist primarily studying ageing, Zhaoli (Joy) has led multiple projects using population-based cohorts, nationally representative survey data, and electronic health records in Singapore, the US, and Australia to study dietary factors and other modifiable risk factors for the development and management of chronic diseases, including hip fractures, osteoarthritis and pain, obesity, cardiovascular disease, and mental health. In addition, her systematic reviews and meta-research assess dietary recommendations in evidence-based public health guidelines and clinical guidelines, with an extent to examine the influence of conflicts of interest in research conduct and dissemination.
Her research addresses the importance of optimal diet and nutrition in improving the quality of ageing life, methodological rigour of evidence-based health guidelines and policies, and equity in healthcare access, particularly for people in racial and ethnic minority groups. She has published over 40 peer-reviewed publications, including those published in top-tier medical journals, including the BMJ, Annals of Rheumatic Diseases, and PLOS Medicine (Published name: Zhaoli Dai).
As a committed public health researcher and educator, her goal is to train students in public health, medicine, or other health disciplines to develop systems thinking and essential analytic skills to address various public health problems.
