He is part of the  team that introduced CT coronary angiography and percutaneous aortic valve implantation into clinical practice in Auckland.

Malcolm's research interests relate to the application of imaging and genomics to the treatment and prevention of ischaemic heart disease, and the diagnosis and management of valvular heart disease. 

Research | Current

Cardiovascular genomics, biomarkers and imaging to more accurately predict cardiovascular risk and personalise therapy.

Malcolm is the principal investigator on MENZACS ( Multi Ethnic New Zealand Acute Coronary Syndrome Study) , and a co-investigator on the National Science Challenge Healthier Lives project for equitable CVD and diabetes risk prediction.

Other fields/areas:

The use of digital technology to enhance medical student teaching in cardiology.

The use of transoesophageal echocardiography in the perioperative setting.

The use of biosensors to assist in diagnosis of cardiovascular disease.
