Dr Morris trained in medicine at the University of Oxford where he won prizes for academic achievement and research. After completing an intercalated degree in Physiology he was awarded a Wellcome Trust scholarship to fund a period of research before commencement of undergraduate clinical training. His postgraduate Medical and Cardiology training was undertaken in Manchester.

He advanced his skills in cardiac ablation and pacing through a clinical fellowship in Pacing and Electrophysiology at the world-leading cardiology department of the Royal Melbourne Hospital led by Professor Jonathan Kalman. During this time he received intensive training in advanced arrhythmia management and ablation, and performed research into mechanisms of atrial fibrillation. He is listed as a heart rhythm specialist performing ablations at https://www.hrsonline.org and www.heartrhythmspecialists.org and in his previous role was of the highest volume operators in Manchester.

He has a strong research interest in heart rhythm disorders. His PhD, funded by the British Heart Foundation, was awarded in 2009 for work investigating the cause of ‘sick sinus syndrome’ and the development of gene therapy for this disease. This research was awarded the Heart Rhythm Society Young Investigator Award and the Turnberg Cup. 

Dr Morris has an ongoing research interest in atrial fibrillation, sinus node disease and arrhythmias in athletes. His expertise and innovation was recently recognised with a grant award of over £800,000 from the British Heart Foundation for research to improve ablation strategies for atrial fibrillation. He is widely published and has been invited to speak at meetings across the world on these topics. He is part of the Cardiac Electrophysiology Research Group at the University of Manchester who are world leaders in the science of heart rhythm disorders, and is working with the team at the John Hunter Hospital to expand the cardiac arrhythmia research program there.
