Gwilym Morris is a cardiologist and electrophysiologist at the John Hunter Hospital, Newcastle. He has a long standing clinical and research interest in electrical remodelling of the heart, including that caused by endurance athletic training. Prior to relocating in 2022 to Australia he worked with Prof Mark Boyett investigating function and disease of the cardiac conduction system, and established the Translational Arrhythmia Research Group in Manchester University, UK. Among other projects the groups worked on athletic remodelling of the sinoatrial node, the atrioventricular node and pulmonary vein arrhythmogenesis.
