Dr Liew is a Senior Consultant (Geriatric Psychiatrist) at Singapore General Hospital, a Clinical Associate Professor at Duke-NUS Medical School, and an adjunct Associate Professor at the NUS Saw Swee Hock School of Public Health. He holds a PhD in Public Health, being a past recipient of the National Medical Research Council’s research fellowship. He has keen interest in Health Services Research (HSR), which stems from his curiosity about the complex nature of healthcare, especially in the context of how human behaviour interacts with the healthcare system. His approach to HSR often involves blending an understanding of the clinical context and human behaviour – together with data analytics – to provide less conventional solutions to the complex issues in the current healthcare system. Through HSR, Dr Liew seeks to leverage on systems-level interventions to improve health-related outcomes and benefit the older population.
