Our research integrates experimental, advanced imaging and mathematical modelling approaches to uncover the molecular and systems-level mechanisms driving infectious and neurodegenerative diseases, aiming to engineer new treatment strategies.
Our research focuses on neurodegenerative diseases such as Alzheimer’s disease and frontotemporal dementia, as well as infectious diseases caused by viruses such as SARS-CoV-2 and Zika. Using advanced imaging techniques, such as super-resolution microscopy, alongside biochemical techniques, we investigate the underlying pathomechanisms. We also develop multiscale mathematical models integrating phenomena from molecular to human population levels to understand treatment failures and predict strategies for improving outcomes. The ongoing projects address the following questions:
- What molecular mechanisms underlie synapse and neuronal loss in neurodegenerative diseases?
- Why are only a subset of neurons impacted by pathology, known as selective neuronal vulnerability, in Alzheimer’s disease and other neurodegenerative diseases?
- What role does innate immunity, including interferon and complement signalling, play in the initiation and progression of Alzheimer’s disease?
- Is there a mechanistic link between vaccination, viral infections, and neurodegenerative diseases?
