Computational Reconstruction of Cardiac Pacemaker Activation and Atrial Propagation. This study seeks to develop accurate computer models of electrical activity in pacemaker and atrial cells of the heart, in order to understand how the heartbeat originates and propagates across the atria during normal and abnormal rhythms. In Australia, atrial fibrillation represents the most common form of chronic cardiac arrhythmia encountered in clinical practice, as well as being a major risk factor in strok ....Computational Reconstruction of Cardiac Pacemaker Activation and Atrial Propagation. This study seeks to develop accurate computer models of electrical activity in pacemaker and atrial cells of the heart, in order to understand how the heartbeat originates and propagates across the atria during normal and abnormal rhythms. In Australia, atrial fibrillation represents the most common form of chronic cardiac arrhythmia encountered in clinical practice, as well as being a major risk factor in stroke. Accurate computer modelling of normal and abnormal heart rhythms will provide greater insights into the development of antiarrythmic drugs as well as advancing knowledge of key electrical phenomena in the heart.Read moreRead less
Function and evolution of optical structures in nature. Designing optical structures that simultaneously satisfy multiple and conflicting criteria and satisfy difficult manufacturing constraints is technologically challenging. However, Nature has been doing this for millions of years. This project is a systematic study of optical structures in one of Nature's most diverse range of species: butterflies. The microstructures inside butterfly scales have an amazing diversity of geometries that produ ....Function and evolution of optical structures in nature. Designing optical structures that simultaneously satisfy multiple and conflicting criteria and satisfy difficult manufacturing constraints is technologically challenging. However, Nature has been doing this for millions of years. This project is a systematic study of optical structures in one of Nature's most diverse range of species: butterflies. The microstructures inside butterfly scales have an amazing diversity of geometries that produce structural colour and are amongst the most complex naturally occurring optical structures produced by a single cell.Read moreRead less
