My clinical interests in the NHS are reflected in the type of patients that I see at the Spire Hospital, with the addition of some patients with medical problems related to diving (SCUBA predominantly).

This stems from my service in the Royal Navy when I was a diving medicine doctor at the Institute of Naval Medicine and the Submarine Escape training tank.

My clinical interests are patent foramen ovale (especially in those who have had a stroke, diving illness and now migraine), novel interventions such as valve implantation (TAVI and pulmonary valves) and all forms of intervention for congenital heart disease.

I have done extensive research on pacing therapy, particularly for heart failure.

I am a proctor (clinical teacher) for St Jude Medical and AGA Medical for PFO closure and appendage occlusion and Medtronic for transcatheter valves, which involves travelling to other hospitals to help them set up their programmes for these techniques.
