​Dr. Fong Sheng is a budding geriatrician clinician-scientist with expertise in the fields of geriatric medicine and geroscience. His research interests include: (1) development of molecular biomarkers for dementia staging in geriatric patients; (2) development and validation of biomarkers of chronic inflammation in ageing-related diseases in order to inform interventions and potential subgroup response; and, (3) development of classifiers of physiological resilience and reserve (e.g. “-omics” based “ageing clocks”) of geriatric patients in order to predict health outcomes and for risk stratification.
