Professor Clark was educated at Pembroke College, Cambridge, and trained in medicine at the Westminster Medical School. He trained in cardiology at Manchester Royal Infirmary, the National Heart and Lung Institute (London) and the Western Infirmary, Glasgow.
He became a Senior Lecturer in cardiology in the University of Hull in 1999 and was promoted to Reader in 2004 and then Professor in 2009. He is responsible for running the echocardiography service in Hull, and he plays an active role in the day-to-day provision of cardiology services to the population of Hull and the East Riding of Yorkshire.
He is Chair of the British Society for Heart Failure, and is a member of the working groups for Heart Failure and Cardiac Rehabilitation and Exercise Physiology in the European Society of Cardiology.
Professor Clark has published over 300 papers, predominantly in the general area of heart failure, but including some work on contraception in primary care! Recent papers in include:

Professor Clark lectures all the years in HYMS, mainly on cardiovascular medicine. He takes a group of third years and is responsible for making certain that they can read an ECG before they leave!
Professor Clark is the current chair of the British Society for Heart Failure, a member of the Board, Council and Executive of the British Cardiovascular Society and a member of the Working Groups for Rehabilitation and Heart Failure for the European Society of Cardiology. He helped produce the UK guidelines on heart transplantation and is on the steering group for several multinational clinical trials. He is the editor of the Oxford Textbook of Heart Failure.
