Neurodegeneration and Neuropathology Group
Our research group focuses on research in Alzheimer’s disease and other related neurodegenerative diseases, including Parkinson’s disease, Creutzfeldt-Jakob disease, Frontotemporal dementia, Huntington’s disease, and age-related molecular degeneration. We have also been focusing on describing the natural history of Alzheimer’s disease as a necessary preparatory step for disease modifying therapies.

About our research
We aim to identify the specific conformer of the Aβ amyloid peptide which accumulates in Alzheimer’s disease brain. In both familial early onset Alzheimer’s disease (in which Aβ is over-produced) and in late onset sporadic Alzheimer’s disease (in which Aβ is poorly cleared from the brain), the same underlying process causes the synapses in the brain to degenerate. Based on this knowledge, we are able to seek imaging and other biomarkers in the CSF and blood and to discover suitable lead compounds that can target the Aβ oligomer itself.
Research projects
- Biomarker discovery for neurodegenerative disease
- Can we achieve precise medication use in people living with Alzheimer’s disease?
- Can we identify novel biomarkers for early detection of Alzheimer’s disease?
- Characterisation of a putative new class of brain glial cells with possible roles in Alzheimer’s disease and related disorders
- Contribution of APOE genome mosaicism to sporadic Alzheimer’s disease
