Dr Lockie attended University College School, before training at Edinburgh University. He undertook an intercalated degree, gaining first class honours. After graduation, he worked in Edinburgh before moving to London for his specialist cardiology training.

With an interest in ischaemic heart disease, he undertook a PhD at King’s College, London, winning the Young Investigator prize, as well as presenting and publishing his work around the world.

He spent a year at the Academic Medical Centre in Amsterdam undertaking further training in advanced percutaneous coronary interventions (PCI). He now works as a consultant interventional cardiologist at the Royal Free London.

Dr Lockie specialises in complex PCI, intravascular imaging and coronary physiology, and has an ongoing interest in research being the principle site investigator for several large studies.

He was appointed as clinical service lead for cardiology across all Royal Free London sites and associate professor of cardiology, Univeristy College London. He has also been elected as a fellow of the European Society of Cardiology.
