Primary Research:

The focus of the group is to understand the basic mechanisms which regulate endothelial homeostasis. Endothelial cells regulate critical vascular functions, such as traffic of cells from blood to tissues, clotting, permeability and angiogenesis. Maintenance of endothelial homeostasis is essential for the prevention and control of vascular inflammatory diseases, thrombosis and atherosclerosis. Endothelial cells are also essential to maintain tissue homeostasis, making this area critical for a wide number of diseases and for regenerative medicine approaches.

The laboratory investigates the molecular pathways that regulate endothelial homeostasis, angiogenesis and vascular stability, with a view to identifying novel target and approaches for the prevention and treatment of diseases. Projects in the group focus on three main areas:

1. Transcriptional and epigenetic control of endothelial homeostasis and angiogenesis by the ETS transcription factor ERG
2. von Willebrand Factor regulation of angiogenesis
3. Circulating endothelial progenitors (Blood Outgrowth Endothelial Cells) in regenerative and precision medicine
