Professional Profile

I am a consultant cardiologist based at the Northern General Hospital. I am one of the primary cardiac device implanters and lead for device and lead extraction. I assist with the running of the inherited cardiac conditions service and have specialist interests in heart muscle diseases and channelopathies. I also assist with delivery of the heart failure service and support the ambulatory intravenous diuretic service and community heart failure team. I have an active research portfolio and am currently PI and sub-PI for 4 clinical trials.
