Our Group

Our research activities are focussed on understanding the different mechanical subtypes among patients with heart failure (systolic dysfunction), in order to develop tailored therapies to improve left ventricular performance. We work in a collaborative framework with a multidisciplinary emphasis, spanning biomedical engineering, cardiology, diagnostic imaging, and population based clinical outcomes.


Identidying clinical markers to separate out groups of heart failure patients with markedly different profiles of left ventricular systolic performance. 
Using integrative functional imaging (echocardiography, magnetic resonance imaging, perfusion and sympathetic scintigraphy) to explore the mechanics and myocyte milieu in patients.
