Gwilym Morris is a British Heart Foundation Intermediate Research Fellow at the University of Manchester and Consultant Cardiologist at Manchester University Foundation Trust specialising in ablation of cardiac arrhythmia, especially atrial fibrillation. He has established a translational arrhythmia research group in Manchester, focussed on improved understanding of atrial arrhythmia mechanisms. 

His research background was initially in sinus node disease and biological pacemaking, working with Professor Mark Boyett. Developing this theme, his current project is investigating the contribution of sinus node disease to electrical and structural remodelling of the atria and how this contributes to the development of atrial fibrillation. Within this project he is interrogating how atrial remodelling contributes to the development of drivers of AF.
