Research interests

My current research aims to develop a method of arterialising human saphenous veins (hSV) for use in coronary artery bypass surgery. An ongoing issue, with detrimental health and economic costs, is the development of thrombosis and lack of graft patency in 50% of autologous or synthetic venous grafts within 10 years of implant. Arterial conduits have been shown to remain patent in >95% of cases at 15-20 years post-bypass, and have improved long-term mortality rates. However, only ~20% of bypass grafts are performed using autologous arteries due to difficulties obtaining tissue and the likelihood of ageing-related arterial disease e.g. atherosclerosis. Using our bioreactor in vitro system, which allows us to perfuse the conduits at venous to arterial pulsatile pressures, we hope to develop cell seeding strategies and modify haemodynamic properties to turn decellularised hSVs into arteries for implant, which remain patent.

Following an 18-month change in research direction, developing methods to optimise islet cell transplantation in patients with Type I diabetes, this project returns to my scientific roots in cardiovascular research. My PhD at Imperial College London, and subsequent postdoctoral research in Bristol Heart Institute, focussed on changes in blood flow patterns, wall shear stress (haemodynamics), vessel wall mechanics and their effects on atherosclerosis development and atherosclerotic plaque rupture.  

In Bristol, we are in the unique position of having the recently opened Translational Biomedical Research Centre (TBRC) for large animal work, and also have access to patient samples through the Bristol Royal infirmary and Bristol Children’s Hospital.
