$380,558.00
Summary
Muscle wasting is a consequence of aging, cancer, HIV-AIDS, obesity and work-sport injuries. It increases the risk of injury, impacts on recovery and places an economic burden on our healthcare system. Atrogin-1 and STARS are muscle specific genes believed to regulate muscle mass. This project aims to determine how human atrogin-1 and STARS are regulated and how they can influence muscle loss. These studies may provide new targets for reducing human muscle wasting.
In Vivo Responses To Pathogen-derived Mediators Of Acute Inflammation

Funding Amount
$94,250.00
Summary
Sepsis causes large numbers of deaths worldwide. It is not known why some patients tolerate an infection and fully recover, while other patients with an equivalent infection are highly vulnerable to severe illness and death from sepsis. Heart failure is a common underlying condition in sepsis. This research will focus on how an infection can cause sudden cardiac death. It will have implications for care of patients with severe infection and also sudden infant death syndrome.
Bacterial Pathogenomics: Whole-genome Sequencing To Investigate Infection Transmission, Pathogenesis And Antibiotic Resistance

Funding Amount
$475,946.00
Summary
As bacterial superbugs – resistant to multiple antibiotics – dominate the headlines, the pipeline for new antibiotics has all but dried up. High-throughput DNA sequencing heralds a golden opportunity for infectious disease research. By studying the entire collection of genes - the genome - of large numbers of multidrug resistant bacterial strains, we aim to better understand the genetic changes that govern the emergence and global spread of superbugs and translate these findings into the clinic.
Addressing Important Evidence Gaps In The Management Of Severe Infectious Diseases

Summary
There are currently large gaps in the evidence base for management of common severe bacterial infections. My research plan focuses on the most common of these: Staphylococcus aureus infections, bone and joint infections, skin infections, and severe sepsis. In order to both generate important evidence to inform practice, as well as to develop my own skills and experience as an expert in clinical trials, I have initiated randomised controlled trials in each of these areas.
Immunological Mechanisms And Management Of Serious Illness And Injury
Funder
National Health and Medical Research Council
Funding Amount
$334,539.00
Summary
This fellowship will improve outcomes for seriously ill and injured people, in particular anaphylaxis (life-threatening severe allergy), sepsis (infection) and severe brain injury. Novel laboratory research will be brought to the emergency bedside and integrated with clinical trials aimed at improving outcomes from these conditions. As well as providing immediate benefits in terms of understanding disease processes, this research will pave the way for new therapeutic approaches in the future.
Determining The Bacterial Contributions To Tuberculosis And Identification Of Drug Targets

Funding Amount
$443,946.00
Summary
Serious issues of drug resistance have emerged in tuberculosis prevention and are placing enormous pressure on global health systems. We have identified an enzyme of M. tuberculosis that is essential for its survival. This project will develop potent inhibitory compounds for this enzyme. Further, we will identify new drug targets through a screen to specifically identify the genes of the organism essential for its survival in the body. This information will be used to develop new TB drugs.
Structural Characterization Of A Novel AB5 Cytoxin - SubAB
Funder
National Health and Medical Research Council
Funding Amount
$210,760.00
Summary
The proposed research program, using a combinantion of structural biology and biophysical techniques will provide insight into the role of novel AB5 toxin from E. coli. This study will not only improve our fundamental understanding the mode of action of this toxin from this devastating pathogen, but could lead to the design of rational antimicrobials. The knowledge gained will increase Australian international research profile.
Targeting Bacterial ÏsuperbugsÍ By Innovative Combination Dosing Strategies And New Antibiotics

National Health and Medical Research Council
Funding Amount
$463,650.00
Summary
This research project will elucidate the mechanistic basis to optimally combine available beta-lactam antibiotics to prevent resistance of gram-negative bacterial ïsuperbugsÍ. These mechanistic insights will be utilised to develop novel antibiotics that are active against these multidrug-resistant bacteria. The interdisciplinary project will substantially contribute to solving the global crisis due to multidrug-resistant bacteria and inform the design of effective new antibiotics.
Impact Of Pneumococcal Vaccination And Environmental Factors On Pneumococcal Carriage And Disease.

Summary
Pneumonia is the leading killer of children <5y of age worldwide, and the pneumococcal bacterium is a common cause. Pneumococci are carried in the noses of healthy children. In this project we will determine 1) whether carriage can be used to monitor the impact of vaccination in resource-poor settings, 2) the effect of new vaccines on ear disease and transmission using infant mouse models and 3) if exposure to smoke effects the ability of pneumococci to cause disease and altered gene expressi ....Pneumonia is the leading killer of children <5y of age worldwide, and the pneumococcal bacterium is a common cause.
