CHEUNG Yin Bun is a Professor at Duke-NUS Medical School, Singapore, and Adjunct Professor at Tampere University, Finland. Prior to joining Duke-NUS in 2012, he served as a senior lecturer at the London School of Hygiene & Tropical Medicine and Chief Scientific Officer at the Singapore Clinical Research Institute.

He received his degrees in social science, medical demography, statistics and paediatric epidemiology from institutions in Hong Kong, Singapore, and the United Kingdom. He has broad interest in the studies of child health, statistical methodology, and health and quality of life outcomes.

As of 2021, he is the principal investigator of a statistical methodology study to improve the design and analysis of vaccine and infectious disease studies (funded by the National Medical Research Council) and a study to evaluate the measurement of quality of life of family caregivers of patients with chronic heart disease (funded by the Lien Center for Palliative Care).

He is the author of Statistical Analysis of Human Growth and Development (CRC Press, 2014) and co-author of Survival Analysis: A Practical Approach (Wiley, 2006). He is the developer of the Singapore Caregiver Quality of Life Scale.

 

Research Interest

Design and analysis of studies of vaccines and pharmaceutical preventive measures against infectious diseases

Recent developments in vaccines and pharmaceutical prevention measures often involve conditions that can recur, such as acute gastroenteritis, malaria and pneumonia, as opposed to diseases that can only occur once in a lifetime. In a series of research projects funded by the National Medical Research Council, Professor Cheung and his team have been investigating efficient and robust approaches to study design and statistical analysis of recurrent events, covering individual and cluster randomized trials, case-control studies and within-unit comparative methods. These developments have been motivated by and applied to studies of child health in low-income countries.    

Quantification of patients’ and caregivers’ quality of life and health utility

Professor Cheung and his team develop and evaluate methods and measurement scales to quantify patients’ and caregivers’ quality of life and health utility, with focus on suitability and usability in Asian and clinical settings. Some recent achievements include the development of the Singapore Caregiver Quality of Life Scale and its short forms and sample size determination formula for EQ-5D-5L value set studies. These developments have been motivated by and applied to studies of patients with palliative or long-term care needs and their caregivers.
