Professional Profile

I graduated in Medicine from Cambridge University and trained at several London teaching hospitals in general internal medicine. I then spent 3 years in full time research at Oxford to gain an MD degree. I returned to clinical cardiology training in East Anglia (mainly at the regional centre Papworth Hospital) and finally completed cardiac electrophysiology training with an 18 month fellowship in the internationally renowned unit at the Royal Melbourne Hospital, Australia. I am an internationally accredited specialist in both cardiac electrophysiology and devices (IBHRE).
 
I started as a consultant at Sheffield in January 2014 and together with colleagues provide the regional Cardiac Rhythm Management service. I hold regular arrhythmia clinics and perform the full spectrum of interventional electrophysiology procedures (catheter ablation and device implants/extraction). I also contribute to the general cardiology on call service, looking after acute cardiology inpatients. I am committed to education and training - currently I am the lead for junior doctors within cardiology (core medical/foundation programme). I am also actively involved in clinical research, aimed at better understanding of arrhythmia mechanisms and improving patient care.
