I'm an evolutionary biologist by training, but my current research includes field ecology, molecular biology, phylodynamics and bioinformatics. I take a systems biology approach to asking questions about how our changing world (and especially urbanisation), is likely to impact infectious disease risk for people living in the tropics.

The ecological and evolutionary factors influencing the establishment and persistence of community associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in resourcelimited, high-burden settings
- Indicative Funding
- $603,908 over 3 years
- Summary
- Our preliminary data suggests that there is high circulation of methicillin resistant Staphylococcus aureus (CA-MRSA) in the highlands of PNG. We propose a hospital- and community-based study to determine the ecological and evolutionary factors associated with the establishment of the highly virulent MRSA ST93 clone in the highlands of PNG. This study will provide vital information for clinicians, public health professionals and policy makers in PNG to guide treatment and interventions to reduce the impact of MRSA-associated AHO in the country. Indeed, these findings will also inform strategies for the treatment and prevention of MRSA-associated AHO in other resource-limited settings.

Can portable genome sequencing provide a rapid, comprehensive, point-of-care diagnostic test for Far North Queensland hospitals and healthcare centres?
- Indicative Funding
- $49,987 over 2 years
- Summary
- Respiratory disease, fevers, and sepsis are common in FNQ and treatment often requires admission to hospital. These infections have many different causes, and diagnosing them requires multiple tests that take weeks to perform. Consequently, patients are treated with broad-spectrum antibiotics before a pathogen is identified, leading to poorer outcomes for the patient and contributing to the spread of antibiotic-resistant infections. We will trial new genome sequencing technology as a point-of-care diagnostic test for fever, sepsis, and pneumonia at Cairns Hospital, and test the hypothesis that this approach will increase the proportion of infections that are diagnosed and reduce the time-to-diagnosis.

Portable genome sequencing as a point-of-care diagnostic test in remote tropical Australia.
- Indicative Funding
- $36,159 over 1 year
- Summary
- Respiratory disease, fevers, and sepsis are common in tropical northern Australia, and treatment often requires admission to hospital. We will trial new portable genome sequencing technology as a point-of-care diagnostic test for fever, sepsis, and pneumonia at Thursday Island Hospital in Far North Queensland. We will test the hypothesis that this new approach will increase the proportion of infections that are diagnosed and reduce the time it takes to achieve a diagnosis. Throughout the course of this project, clinical staff and health workers will have the opportunity to be trained in specimen preparation, genome sequencing, and data interpretation.

Metagenomics for Pathogen Detection and Dynamics in Australia?s Tropical North
- Indicative Funding
- $182,779 over 2 years
- Summary
- Metagenomic NGS (mNGS) can reveal features of the host response to infection, identify genes associated with antimicrobial resistance or virulence, and allow for real-time epidemiological tracking of outbreaks. Given the complex clinical and epidemiological landscape of Australia?s tropical north, mNGS techniques have the potential to improve diagnostic capabilities, reduce time-totreatment and exposure to unnecessary antimicrobials, and increase our understanding of the patterns of emergence and spread of infectious diseases in the region.
