Current research interests

Our research aims to understand how cerebrovascular dysfunction contributes to neurodegeneration and dementia in order to identify new therapeutic targets.

We combine molecular approaches with advanced imaging in experimental models, including MRI and microscopy, to investigate the causes and consequences of blood-brain barrier (BBB) dysfunction in ageing and neurodegenerative disease. A central focus of the lab is the interaction between pericytes and endothelial cells that maintain microvascular stability. Disruption of this crosstalk is increasingly recognised as a key driver of vascular dysfunction, inflammation, and metabolic imbalance in the brain.

Using genetic mouse models of pericyte ablation, AAV-based approaches to induce endothelial dysfunction, and models of cerebral amyloidosis, we study how vascular injury develops and propagates across the neurovascular unit. We are particularly interested in the heterogeneity of pericyte and endothelial subpopulations along the arteriovenous axis and how these specialised vascular cells change during ageing and disease.

Ultimately, our goal is to identify mechanisms and therapeutic strategies that preserve BBB integrity and vascular function in cerebral small vessel disease and Alzheimer’s disease.

Research in a nutshell

The brain relies on a dense network of blood vessels to deliver oxygen and nutrients while tightly controlling its internal environment through the blood-brain barrier (BBB). Increasing evidence shows that breakdown of this barrier is one of the earliest events in disorders that lead to dementia.

Our research focuses on understanding why this vascular barrier fails. In particular, we study pericytes - specialised cells that support brain capillaries and help maintain BBB integrity. Using advanced molecular approaches and in vivo imaging, including MRI and microscopy, we investigate how dysfunction of these cells disrupts vascular stability and brain function.

By uncovering the mechanisms that drive BBB breakdown, our goal is to identify new strategies to protect the brain vasculature and prevent cognitive decline.
