My research focuses on psychiatry and geriatrics. Both are interpreted broadly to include well-being related to mental health and cognitive/ageing health, rather than only disease meeting diagnostic criteria. In a clinical view, I’m especially focusing on the diagnosis, prognosis, and medicine management of mild cognitive disorders and dementia. In the public health and global health view, I'm also especially focusing on social support and health service utilization, as well as corresponding equity, for people with cognitive disorders.

Research methods include analysis of cross-sectional or longitudinal survey data or electronic clinical records, causal inferences, structural equation modelling, policy/intervention simulation, machine learning, mixed qualitative and quantitative observational studies, economic evaluation, and systematic reviews. My research is inherently multi-disciplinary and involves strong links with epidemiology, statistics, health economics, public health, global health, mental health, and ageing health.
