Professor Martyn Nash

BE(Hons), PhD


The primary focus of Martyn's research career has been on bioengineering analyses of the heart in order to understand mechanisms and events underlying cardiac electro-mechanical activity. His PhD focussed on computational modelling and imaging of cardiac mechanics, and subsequently (as a post-doctoral fellow at the University of Oxford from 1997-2002) he established experimental and clinical research programmes to study the electrophysiological function and dysfunction of the heart.

Since returning to Auckland in 2003, Martyn has continued his heart research in collaboration with colleagues in the UK, NZ and Europe. He has also developed new bioengineering research themes applying his modelling and analysis expertise to other organ systems - specifically studying biomechanics of the breast, skin, pelvic floor, lungs, tongue, head (shaken baby syndrome) and equine hoof - much of this through the variety of graduate students that he has supervised.

He develops and applies novel and efficient computational tools in order to interpret the variety and vast quantity of biological observations and recordings that are available from laboratory and clinical studies. He is also engaged in the design and refinement of experimental techniques, medical imaging and bioinstrumentation in order to generate data of sufficient quality to further inform the mathematical modelling analyses. This continual interplay between biological observation, instrumentation and mathematical modelling provides mechanistic insight into physiological function.

Martyn strives to apply this research to facilitate (i) the development of improved medical imaging, biomedical devices and diagnostic techniques, and (ii) the elucidation of possible therapeutic targets for prevention and treatment of disease.
