My research interest lies in obtaining a deeper understanding of the proteinopathies, which lead to neurodegeneration with the use of advanced neuroimaging techniques and fluid biomarkers. My research work so far has focussed on Alzheimer's disease and other causes of dementia. As a physician, I am particularly interested in the incorporation of validated biomarkers to clinical practice for the purpose of diagnosis at the early stages of the disease, as well as evaluation of therapeutic efficacy once disease-modifying treatments become available.
