Summary
A fundamental question in neuroscience is how the brain selectively processes sensory information to generate a reliable representation of the world. Positioned in the centre of the brain, the thalamus plays a key role in sensory processing. This project investigates how the interaction between thalamus and cortex shapes the selection and gating of sensory information. This is a fundamental question in basic neuroscience with the potential to increase our knowledge about attentional deficits.

Summary
We have developed a novel animal model by which to study arthritic disease caused by insect-transmitted viruses known as arboviruses. The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal.

The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal. The production by our immune systems of soluble mediators (cytokines-chemokines) and antibodies is an overwhelming positive aspect of our physiological response to infection by microbes. Protection from disease by these immune compounds can happen naturally, or the body's ability to produce these factors can be exploited to our benefit via the administration of vaccines. However, these factors can also be detrimental to the host contributing to severe disease. For instance, work performed almost 40 years ago showed for the first time that under particular conditions, antibodies against viruses can enhance infection, instead of inhibiting infection as normally seen. In the intervening years work by scientists all over the world has associated antibody-dependent enhancement (ADE) of infection to many types of viruses; ADE is even thought to be a risk factor to serious disease with dengue virus, and has been shown in vitro for the AIDS virus and Ebola virus. We have recently discovered a molecular mechanism which explains how antibody enhances viral infection in vitro. In studies on immune cells infected with Ross River Virus (RRV) we found that infection helped by antibody resulted in the specific disruption to the production of cellular chemicals which are toxic to viruses. Are these mechanisms of antibody-enhanced infection also found in animals? Will such mode of infection cause enhanced disease and tissue pathology (arthritis) in animals?Read moreRead less

This project aims to analyse the illegal parrot trade by utilising conservation genomic approaches. The project will reveal wildlife trade routes in South-east Asia by developing cutting-edge forensic genomic techniques and criminological methods. Expected outcomes of this project include new field-deployable sequencing technology to provide in-situ genetic information for identifying the taxonomy and provenance of confiscated specimens, and a first ever genetic database of traded wildlife. The project will facilitate important countermeasures to the illegal wildlife trade including confiscation, reintroduction, improved law enforcement, and education for better biodiversity outcomes in our region.Read moreRead less
The Molecular Basis of Nanoparticle Resistance in Mixed-Species Biofilm. The project aims to understand how the globally significant mixed-species growth of pathogens develop resistance to silver nanoparticle, currently one of the most important alternative antimicrobials to antibiotics.

The project aims to understand how the globally significant mixed-species growth of pathogens develop resistance to silver nanoparticle, currently one of the most important alternative antimicrobials to antibiotics. The integrated research is to elucidate, for the first time, the nanoparticle multi-targeting toxicity on mixed-species bacterial community and how, in turn, the bacteria activate their cell-to-cell signalling for a synergistic defence to adapt to the nanoparticle toxicity. The pioneering knowledge is the foundation for technologies targeting the interspecies metabolite cross-talking to overcome the resistance phenomena, ensuring a long-term efficacy of the alternative antimicrobial on the difficult-to-control pathogenic growth.Read moreRead less

Australian facility for taphonomic experimental research: The aim of this project is to establish a unique Australian research facility dedicated to studying the physical, chemical, and biological processes of human decomposition. This facility will be the first of its kind in Australia and the Southern Hemisphere, drawing together a collaborative team of experts in a broad range of taphonomy disciplines. The results of the research are expected to advance our limited understanding of the taphonomic processes acting on remains in a natural Australian environment. The outcomes will assist police and forensic services to improve their procedures for searching, locating, recovering, and identifying missing persons, victims of homicide, and victims of disaster on both a national and international scale.Read moreRead less

Floods are the biggest and severest natural disaster we face year after year. Furthermore, there has been little improvement in our capability to prevent flood damage over past decades. This research proposes a paradigm shift in the way flood forecasting, warning and evacuation proceeds, using 21st century technologies for collecting and incorporating flood related data into existing modelling platforms. It is argued that assimilating real-time satellite soil moisture data into flood models can increase accuracy manifold, even if the images are uncertain. The understanding gained in course of the proposed project has the potential to significantly reduce the damage caused year after year, especially in the data poor regions of the world.Read moreRead less

This project aims to identify the causal effects of counter-COVID school closures, stay-at-home mandates and government support payments on the educational and developmental outcomes of Australian children. It will establish, for the first time, a comprehensive causal evidence base on the average and distributional impacts of these policies on children across the spectrum of schooling years from preschool to secondary school completion. This project expects to advance our understanding of child skill accumulation and the relative importance of schools, parents, peers and government intervention. Anticipated benefits include providing policy recommendations to restore student learning outcomes and reduce educational inequality in Australia.Read moreRead less

Human RSV is a major cause of morbidity and life-threatening respiratory tract disease in infants and young children worldwide, and is recognised as an important respiratory pathogen in elderly adults and immune compromised patients. The recent isolation of HMPV from children hospitalised with respiratory tract illness similar to RSV, but with an unknown etiology, suggests that HMPV may mediate similar clinical pathology. Nothing is currently known about the immune response to HMPV, or the association of these responses with lung disease. The objectives of this proposal are to elucidate the mechanisms of immunity and disease pathogenesis associated with human metapneumovirus (HMPV) and to investigate the use of a novel vaccine to protect against HMPV infection. Once this data is obtained, the study will provide the foundation for further research in the development of vaccines or therapeutic protocols to treat HMPV. It will also provide valuable information for understanding the disease in humans. Also,it is likely that HMPV, like hRSV, may prove to be an agent associated with long-term decreased pulmonary function and airflow limitation perhaps developing to asthma.Read moreRead less

This project aims to study and provide ways to overcome vulnerability in Indonesia. Half the Indonesian population is still clustered around the poverty line, contributing to their vulnerability. This project will identify vulnerable groups and why they are vulnerable. Using a common framework of the life course in eight Indonesian field sites, this project will investigate whether social networks and welfare programs reduce vulnerability, and pinpoint strategies for reducing vulnerabilities in the future. The project expects to show how vulnerable citizens in Indonesia can be made more secure, helping to build a more stable and prosperous region.Read moreRead less
