I qualified from Guy's and St Thomas' Hospitals Medical School in 1996 graduating with University Honours. I underwent post-graduate training at Hammersmith, Royal Brompton and King's College Hospitals in London and undertook a two year interventional cardiology fellowship at the Aalst Cardiovascular Centre in Belgium. I was appointed as Clinical Lecturer in Cardiology at King's College London in 2008 prior to taking up my current post as Consultant Cardiologist at King's College Hospital in 2010.
I have received over 11 awards, scholarships and prizes including the British Cardiac Society John Parker Fellowship (2005-2007) and Golding Bird and Treasures Medals.
In 2012 I was invited to join a panel of 5 cardiologists to provide a comprehensive round-the-clock cardiology opinion for the Olympic Family during the 2012 London Olympic Games.

Consultant Cardiologist - King's College Hospital
Honorary Senior Lecturer Cardiology - King's College London
Ongoing clinical research programme with emphasis on applied coronary physiology and all aspects of interventional cardiology, in particular myocardial infarction. Involved in multiple international clinical trials. To date I have co-supervised two students at King's College London.
My work is supported through a number of scientific grants and over the past five years I have received awards from the British Cardiac Society, British Heart Foundation and National Academy of Sciences.
Throughout my career I have received over 11 Awards, Scholarships, Prizes and Medals in cardiology as well as medicine including the prestigious British Cardiac Society John Parker Fellowship (2005-2007), the Ford Caiger Prize in Cardiology, the Golding Bird Medal in Molecular Biology and the Treasurers' Medal of Guy’s and St Thomas’ Hospitals.
