This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum performance, delivering typically less than 20% of the loaded dose to the target site, the lungs. The new fundamental knowledge resulting from this research will enable the engineering of a high-efficiency groundbreaking DPI, with the potential to be fully adaptive user-specific benefiting millions of Australians.

Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it.

This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infecti ....Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infection pressure settings, as a chemo-preventative for these disease agents. Tropical regions spanning northern Australia and Southern Asia are highly conducive to a plethora of canine vector-borne and parasitic pathogens that cause significant morbidity and mortality in dogs. Many of these agents also pose a risk to public health. The outcomes will be directly translated to best-practice guidelines for the advancement of companion animal (and indirectly human) health and welfare.Read moreRead less
Reducing health disparities for culturally and linguistically diverse peoples. This project aims to develop a greater understanding of migrants and the factors that predict poor health outcomes related to blood-borne viruses and sexually transmitted infections. The delayed access by migrants to healthcare from culturally and linguistically diverse backgrounds results in late diagnosis, low treatment uptake, and poorer health outcomes, with enhanced risk of infection and increased burden on the h ....Reducing health disparities for culturally and linguistically diverse peoples. This project aims to develop a greater understanding of migrants and the factors that predict poor health outcomes related to blood-borne viruses and sexually transmitted infections. The delayed access by migrants to healthcare from culturally and linguistically diverse backgrounds results in late diagnosis, low treatment uptake, and poorer health outcomes, with enhanced risk of infection and increased burden on the health system. The data collected in this project will assist in developing health services to meet these needs.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less

The knowledge of the diversity of infectious disease-causing agents in NSW dairy cattle is not comprehensive. Thus, the immediate goal of this proposal is to redress this knowledge gap using untargeted microbial genomic sequencing to characterise and identify known and emerging enteric and respiratory pathogens in dairy calves. We will determine the occurrence and distribution of their microbial species across all NSW dairy regions. This will enable the Australian dairy industry to improve animal health and productivity, and diagnostic capacity, which will allow farmers to make informed management decisions about disease control strategies.
