Investigating the molecular function of alpha-Haemoglobin stabilising protein. The research described in this proposal will provide new insights into haemoglobin regulation and redox chemistry in erythrocytes. Deregulation of these processes gives rise to a number of debilitating diseases, including varieties of anaemia and thalassaemia-in Australia it is estimated that 3% of the population could be carriers of b-thalassaemia mutations.

The research described in this proposal will provide new insights into haemoglobin regulation and redox chemistry in erythrocytes. Deregulation of these processes gives rise to a number of debilitating diseases, including varieties of anaemia and thalassaemia-in Australia it is estimated that 3% of the population could be carriers of b-thalassaemia mutations. Given the contribution of free aHb to the pathology of b-thalassaemia, understanding the specific aHb-binding factor, AHSP is a goal of national significance. In the long term, manipulation of AHSP function through gene therapy may have a direct role in the treatment of thalassaemia.Read moreRead less
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that dr ....The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that drives expansion? How is expansion controlled spatially? These questions will be addressed in this project by comprehensive study of ion transport processes in a model organism, Neurospora crassa, using osmotic sensitive and transport mutants.Read moreRead less
Advanced matrix-analytic methods with applications. Over the last twenty-five years, matrix-analytic methods have proved to be very successful in formulating and analysing certain classes of stochastic models. Motivated by applications, this project will investigate more advanced matrix-analytic methods than have hitherto been studied.
Sustainable fiscal federalism and reform of the GST distribution system. The primary source of funds for Australian States and Territories is GST revenue distributed by the Commonwealth using an equalisation formula that has proved to be politically unsustainable and in recent times manifestly inadequate to provide the revenue needed in response to crises and natural disasters. A tipping point has been reached and reform is urgently needed. Drawing on international experience with GST distributi ....Sustainable fiscal federalism and reform of the GST distribution system. The primary source of funds for Australian States and Territories is GST revenue distributed by the Commonwealth using an equalisation formula that has proved to be politically unsustainable and in recent times manifestly inadequate to provide the revenue needed in response to crises and natural disasters. A tipping point has been reached and reform is urgently needed. Drawing on international experience with GST distributions specifically and fiscal federalism more generally, the project aims to develop a reform blueprint for a sustainable and equitable fiscal federalism regime in Australia that best aligns with Australia’s current and long-term fiscal needs.Read moreRead less
Visualising neuron-glia interactions in the injured central nervous system. The adult brain and spinal cord recovery poorly from injury. Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain.

Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain. This project will use the latest, cutting-edge microscopy techniques to visualise whether the endogenous astrocyte protein metallothionein can promote regeneration in the injured nervous system of living zebrafish. The successful outcomes of this project will provide significant insight into understanding how the brain responds to injury.Read moreRead less

Summary
Primary open angle glaucoma is a chronic eye disease and one of the leading causes of visual impairment and blindness worldwide. This study will use cutting-edge genetic methods to look at the entire coding component of the human genome (exome) in 271 individuals from large glaucoma families. Our previous studies have shown that these families carry genetic variants that increase disease risk. In this investigation we aim to identify these genes, with the hope they may offer novel targets for tr ....Primary open angle glaucoma is a chronic eye disease and one of the leading causes of visual impairment and blindness worldwide.

Change Detection in Causal Relationships and Measurement of Systemic Risk. Empirical measures of interconnectedness between financial institutions based on tests of Granger causality are currently used in detecting systemic risk. However, researchers need to define periods of calm and stress exogenously in order to implement these tests appropriately. This project aims to develop a new procedure to identify changes in causal relationships and the timing of these changes. The new approach has the ....Change Detection in Causal Relationships and Measurement of Systemic Risk. Empirical measures of interconnectedness between financial institutions based on tests of Granger causality are currently used in detecting systemic risk. However, researchers need to define periods of calm and stress exogenously in order to implement these tests appropriately. This project aims to develop a new procedure to identify changes in causal relationships and the timing of these changes. The new approach has the potential to be a significant improvement in the real-time identification of emerging turmoil in financial markets and provide an improved method for the detection of systemic risk. The new test procedure will be implemented using data for financial and non-financial institutions across Europe, the US and Australia.Read moreRead less

Response inhibition is the ability to stop actions that are in progress but become no longer appropriate, such as halting an order to launch a missile strike when a civilian vehicle is detected. The project focuses on people’s ability to either stop all planned actions or selectively stop some actions while allowing others to occur. The goal is to develop methodology to reliably measure the time it takes to stop actions, investigate the psychological mechanisms involved in stopping, and develop tools for defence-related personnel and job selection. The project provides significant benefits by enabling the study of how response inhibition ensures that appropriate actions occur and how failures of inhibition result in inappropriate actions.

This project will analyse how changes in institutional memory inside government impact on the effectiveness of public policy processes. Institutional memory changes as ministers, public servants and public agencies come and go, but we don’t know what effect these changes have over the quality of public policy. This project will therefore analyse how changes to institutional memory have influenced public services and policies in Australia and the UK. Expected outcomes include best practice recommendations for government - about how to address memory loss to improve public policy - and novel academic findings about how institutional memory influences the character of public service delivery, lesson-learning and long-term reform.Read moreRead less
