I qualified in 1989 from Glasgow University MB ChB with commendation, and was awarded the Andrew J. Hutton Medal and Prize in Surgery, and the Asher Asher Memorial Medal and Prize in Otolaryngology.

Most of my training was within the west of Scotland and I took up my first Consultant post at Ayr Hospital in 2001.  I gained a doctorate (MD) from the University of Glasgow in 2002, and in 2006 moved to UCL Hospitals NHS Trust as Consultant Cardiologist.

I am the Director of Barts Heart Centre. Barts Heart Centre is one of the largest cardiovascular centres in Europe. It was formed in 2015 from the merger in 2015 of the cardiac centres at University College London Hospitals NHS Trust, St Bartholomew’s Hospital and the London Chest Hospital. I became Director in 2019.

I am married with three children and live in Pinner, north-west London.  I play golf (badly) and am involved in my local community.
