Haemodynamic investigation of flow diverter stents for the treatment of intracranial aneurysms. This project will explore the engineering of a flow diverter, an endovascular device for the treatment of brain aneurysms. The project will determine the optimal design of new types of flow diverters, which in turn could improve the effectiveness of treatments, thus reducing the associated costs of cerebral haemorrhage and stroke.

The curable precursor of cervical cancer is cervical intra-epithelial neoplasia (CIN). Various cancer probes will be constructed for the identification of CIN based on electrical measurements on tissue. Through studies of the cellular structure and the junction between cells, a theoretical model of the electrode/mucus/tissue system will be developed at and below the surface of the tissue under examination. Theoretical modelling, probe development and detection algorithms will be used to identify CIN in real-time with concurrently high sensitivity and specificity. Effective electrical probes for early detection of cancer (cervical, lung and breast) will be of enormous national and international benefit.Read moreRead less
Dynamic magnetic resonance imaging in orthopaedics. The research in this proposal aims at developing new imaging systems that enable joints to be imaged while they are moving.

Also, acute injuries to knees, hips, shoulders and other joints will be able to be better diagnosed and hence improve treatment planning as a result.Read moreRead less
Combined optical and electrical stimulation of auditory neurons. The bionic ear, which has now helped to improve the hearing of over 200,000 people worldwide, is a great example of Australian innovation success. This project aims to develop the fundamental technology that will underpin the next generation of these devices using a combination of infrared light and electrical signals to stimulate auditory nerves.
Intelligent training (iTraining) for the human Achilles tendon. The project aims to improve understanding of the mechanical environment of the Achilles tendon. The Achilles tendon plays a crucial role in human motor function and is also a structure that is commonly injured and notoriously difficult to treat. A major barrier to improving Achilles tendon function, preventing tendon injury and enhancing tendon repair is a poor understanding of the mechanical environment of the Achilles tendon durin ....Intelligent training (iTraining) for the human Achilles tendon. The project aims to improve understanding of the mechanical environment of the Achilles tendon. The Achilles tendon plays a crucial role in human motor function and is also a structure that is commonly injured and notoriously difficult to treat. A major barrier to improving Achilles tendon function, preventing tendon injury and enhancing tendon repair is a poor understanding of the mechanical environment of the Achilles tendon during training and rehabilitation. The project aims to develop a better understanding of the loading conditions that optimise tendon metabolism. Based on this, it then intends to develop new technologies to estimate the mechanical behaviour of the human Achilles tendon in real time based on integrated use of wearable technology, and new training guidelines that will optimise human tendon adaptation.Read moreRead less

Copycat companies have arisen overseas, but Cochlear Ltd. remains the market leader, due to their commitment to ongoing R&D. The present project involves magnetic resonance imaging and finite element analysis to study the current leakage pathways in the cranial cavity for the purpose of optimizing the design and placement of the return electrode. The obvious benefit of this is longer battery life. Better understanding of current leakage over other intracranial nerves is the other anticipated benefit.Read moreRead less
Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device. The Holy Grail for developers of rotary blood pumps used as left ventricular assist devices is to control the pump to meet the body's metabolic demand and to do this without the need for implanting additional sensors. The controller must also detect and avoid dangerous states associated with over and under pumping.
In this research we will derive and implement a pump control algorithm that will ....Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device.
