My research is focused on translational research in Alzheimer’s disease and related dementias (ADRD), specifically in delineating the pathogenic mechanisms linking AD and other common neurodegenerative and vascular pathologies. My current research focus is on limbic-predominant age-related TDP-43 encephalopathy (LATE), a common brain pathology that causes amnestic dementia in the elderly. I am pursuing several lines of inquiry, including:
- What is the pathogenic role of arteriolosclerosis in LATE?
- What are the key differences between pure LATE and LATE + AD?
- How do we definitively differentiate LATE from FTLD-TDP (frontotemporal lobar degeneration with TDP-43 lesions)?
My collaborative research involves:
- Developing biomarkers for early diagnosis of AD and differentiating AD from other tauopathies.
- Investigating the molecular mechanisms of differential AD susceptibility by spatial transcriptomic profiling.
