About

I have worked as a Consultant Cardiologist in Cambridge for 15 years and am based at Addenbrooke's Hospital and Royal Papworth Hospital. I have extensive experience in all aspects of general cardiology and a subspecialty interest in interventional cardiology.
Following undergraduate training at Cambridge University, I undertook postgraduate medical training at The Royal Brompton National Heart & Lung Hospital and the Oxford University Teaching Hospitals. I returned to Cambridgeshire in 1996 and trained in all aspects of cardiology, with particular emphasis on interventional cardiology. During this period I was awarded a PhD and the British Cardiac Society Young Research Worker's Prize,for research into mechanisms of coronary stent failure. From 2003-2004, I worked in the Department of Interventional Cardiology at University of British Columbia, Vancouver, gaining extensive experience in advanced interventional techniques and strategies for the treatment of coronary disease.
I was appointed Consultant Cardiologist at Papworth and Addenbrooke's Hospitals in 2005. In this position I provide secondary and tertiary centre care to patients with general cardiac problems (valve disease, heart failure, heart rhythm problems), in addition to those with coronary disease. I am one of the members of the Papworth transcatheter aortic valve implantation (TAVI) team. I was Director of the Addenbrooke's Cardiology Department from 2006 to 2014 and am currently Clinical Lead for Coronary Intervention at Royal Papworth Hospital. I maintain a keen research interest, with a particular focus on coronary physiology, novel techniques for treatment of coronary disease, and percutaneous techniques for treatment of valvular heart disease.
