Research Interests

We use both human and mouse cells in vitro and models of atherosclerosis with genetic manipulation to study the role of specific gene products or cells in atherosclerosis. In particular, we have developed unique cell-type ablation systems to analyse the role of specific cells in vivo. Recent work has focussed on the protective mechanisms that ensure survival in VSMCs, and their defects in disease as well as the triggers for VSMC apoptosis and cell senescence. We have also identified novel mechanisms of regulating cell death receptors in vascular cells and how cell: cell interactions govern cell death.

Our clinical studies have used radiofrequency (virtual histology) intravascular ultrasound and computed tomography to determine the types and composition of plaques that determine patient presentation and future events, and are refining these techniques to examine vulnerable plaque characteristics. Collaborations with physical scientists are ongoing to model the mechanical properties of vulnerable plaques.
