Design and analysis of clinical and population health studies
Professor Cheung and his team have been investigating innovative, efficient and robust approaches to study designs and their associated analytic methods, covering individual and cluster randomized trials, case-control and case-only studies, and real-world evidence research. These developments have been motivated by and applied to studies of global child health, vaccine, and palliative care.

Analysis of recurrent time-to-event and incidence data
Recent developments in vaccines and pharmaceutical prevention measures often involve conditions that can recur, such as acute gastroenteritis and pneumonia, as opposed to diseases that can only occur once in a lifetime. Health services research also often involve recurrent event outcomes, such as emergency department visits and hospital readmissions. Conventional analytic methods that are oriented to studying a single event or first event is not sufficient. Methods to analyse recurrent event data is a key research area of the team.     

Quality of life and health utility amid life-limiting illness
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. They also study factors that affect and interventions that improve health and quality of life outcomes of patients with palliative or long-term care needs and their caregivers.
