    Interests

    I am a Research Associate studying the role of cerebrovascular dysfunction in dementia and cognitive impairment, with the help of multimodal neuroimaging techniques and clinical data in humans. Currently, my research focuses on the associations between cerebral small vessel disease, inflammation, and blood brain barrier permeability. I am also interested in studying the early risk factors of dementia, and how cerebral small vessel disease is involved in early dementia pathogenesis. In particular, I am interested in how cerebral small vessel disease relates to established dementia risk factors and molecular imaging markers of dementia (e.g., amyloid, tau, neuroinflammation), as a way to further our understanding of how various pathologies interact in their contribution to neurodegeneration and clinical outcomes. On top of my academic work, I support younger researchers as the Early Career Investigator Representative of the International Society of Vascular Behavioural and Cognitive Disorders (VasCog) (https://www.vascog.org/).
