High-speed underwater communication is vitally important for Australian offshore oil and gas industries, marine commercial operations, and defence applications. However, due to the challenges posed by the harsh underwater channel, current underwater communication systems have significant limitations on data rate and bit-error-rate for many applications and environments. This project aims to develop a real-time signal processing platform for reliable high-speed communication through the extremely bandlimited and reverberant underwater acoustic channel. New channel estimation, tracking and equalisation algorithms developed in this project will significantly enhance the capacity of underwater communication systems.Read moreRead less
Increasing the range and rate of underwater acoustic communication systems using multi-hop relay. Australia has a very long coastline, thus it is vitally important for Australia to efficiently explore and exploit the rich resources in the ocean. This project develops novel communication technologies for long-range and high-rate underwater acoustic communications that are crucial to Australian ocean-related industries and defence applications.

Electronics of the future: self-powering wireless circuit design. The aim of this project is to build a foundation for ultra-low-power wireless circuit design using technologies other than silicon. Scaling of transistors in silicon has been pushed to its limit and is of marginal benefit for low-power wireless circuit design. This project aims to address these limits by developing energy-efficient technology for wireless applications. The intended outcome of this project will be a self-powered, h ....Electronics of the future: self-powering wireless circuit design. The aim of this project is to build a foundation for ultra-low-power wireless circuit design using technologies other than silicon. Scaling of transistors in silicon has been pushed to its limit and is of marginal benefit for low-power wireless circuit design. This project aims to address these limits by developing energy-efficient technology for wireless applications. The intended outcome of this project will be a self-powered, high data rate receiver that will be critical in 5th-generation wireless systems. This could be used for a range of innovative wireless applications, for example in health care and environmental monitoring.Read moreRead less

Associate Professor Kate Denton is an internationally recognised cardiovascular researcher. A focus of Dr Denton’s research is to find out why women do not respond to current treatments as well as men, and how factors in pregnancy (nutrition, stress, alcohol) drive the development of cardiovascular disease in offspring. Dr Denton is also leading research to understand why a new high blood pressure treatment (blocking nerves to the kidney) is proving more effective than expected.
Responsive transport environments: spatial and visual user information technologies to allow improved passenger flow and a better customer experience.

Summary
We will determine how low oxygen levels in the kidney lead to kidney disease. We can now measure the levels of oxygen in kidney tissue in rats 24 hours a day, 7 days a week, in a completely non-invasive way. We will study two common kinds of kidney disease. One, acute kidney injury, can result from administration of contrast agents used in x-ray diagnostic procedures. The other, chronic kidney disease, is common in patients with diabetes or high blood pressure.
Technology optimisation of integrated circuits with applications to wireless communication systems in medicine. This project will define and verify methods to help engineers pick the best technology for designing critical wireless monitoring systems used for medical devices. This project will also verify these methods by developing a wireless, implantable blood pressure monitor with real-time video.

Summary
Emotional stress triggers physiological reactions that affect our heart and blood pressure. For people with a weak or failing heart, this can lead to stroke and death. This project explores the effects and the sites of action in the brain of two different types drugs that could potentially reduce or prevent such accidents. Unlike the drugs that are currently in use, these two drugs act directly in the parts of the brain that control cardiovascular responses to emotional stress.
RGS5 Signalling In Cardiovascular And Smooth Muscle Cell Physiology

Summary
Cardiovascular diseases, including hypertension, remain one of the largest causes of morbidity and mortality in Western populations. We have identified a molecule, called Regulator of G protein signalling 5 (RGS5), which is involved in pathological vessel remodelling and in the regulation of blood pressure. This molecule is a prime candidate for drug development. We will study the precise role of RGS5 in cardiovascular disease models and regulatory pathways in cell systems.
