Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire ....Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire risk and spread, trained and validated on a two-decade satellite fire record. The predictive ability of the model will be tested on the 2019/20 fire season to determine if novel drivers of fire can be identified, and the model itself will be operationalised into a novel short-to-mid term fire risk prediction tool.

Summary
Atmospheric trace gases: Fuelling the dormant microbial majority. This project aims to determine the physiological roles and ecological significance of hydrogen, methane and carbon monoxide scavenging. Bacteria adapt to adverse environmental conditions such as energy-starvation by entering dormant states. The fuel sources that sustain this dormant majority have yet to be resolved. Aerobic soil bacteria survive by scavenging trace gases from the atmosphere; they literally live on thin air. These ....Atmospheric trace gases: Fuelling the dormant microbial majority. This project aims to determine the physiological roles and ecological significance of hydrogen, methane and carbon monoxide scavenging. Bacteria adapt to adverse environmental conditions such as energy-starvation by entering dormant states. The fuel sources that sustain this dormant majority have yet to be resolved. Aerobic soil bacteria survive by scavenging trace gases from the atmosphere; they literally live on thin air. These trace gas scavengers are the major biological sinks in the global methane and hydrogen cycles. This project aims to study entire ecosystems of trace gas scavengers, which could enhance understanding of soil microbial ecology and biogeochemical cycling. By studying the regulation and distribution of gas scavenging, we can better model how these sinks respond to global change.Read moreRead less
Revealing the microbial process of iron-driven anaerobic ammonium oxidation. This project aims to gain fundamental understanding of the recently discovered microbially-facilitated process of anaerobic ammonium oxidation that is coupled to iron reduction. This process (called Feammox) is suggested to be responsible for significant nitrogen loss from soil and sediment ecosystems, resulting in pollution of the atmosphere and our water systems. In the project, the Feammox microorganisms will be enri ....Revealing the microbial process of iron-driven anaerobic ammonium oxidation.

This process (called Feammox) is suggested to be responsible for significant nitrogen loss from soil and sediment ecosystems, resulting in pollution of the atmosphere and our water systems. In the project, the Feammox microorganisms will be enriched and characterised to reveal the metabolic details of the iron reduction and ammonium oxidation pathways. This will improve understanding of ecosystem nitrogen flux and benefit the management of nitrogen fertilizers used to meet the food and energy requirements of the world’s growing populations.Read moreRead less
Portable instrument for quantification and genotyping of Cryptosporidium . Cryptosporidium is a parasitic protozoan, causing more than 48,000 deaths in children under 5 and 7.2 million disability-adjusted-life-years globally. A low-cost device that rapidly detects the parasite in drinking and recreational water is needed to enable effective disease management practices.

A low-cost device that rapidly detects the parasite in drinking and recreational water is needed to enable effective disease management practices. Partnering with Advanced Universal Diagnotik, Seqwater, ALS Water and Gold Coast Water, this project aims to develop a novel device, comprising advanced microfluidics and biosensing technology for parasite quantification, genotyping and viability analysis. Expected outcomes are improved Cryptosporidium management, risk prediction, and rapid mitigation of impending outbreaks. The proposed platform has a great potential for detecting other pathogens.Read moreRead less

This project aims to investigate tolerance (the ability to limit the detrimental effects of infection) as a key animal defence strategy against disease. It focuses on diseases in natural systems, using the devastating amphibian fungal skin disease, chytridiomycosis, as a model. Expected outcomes include improved understanding of the relative importance of tolerance and resistance, and insight into the key immune and physiologic mechanisms underlying variations in tolerance. Anticipated benefits include improved strategies for mitigating infectious wildlife diseases via identifying targets for therapeutic interventions, ecological management and assisted-evolution strategies. This project should also benefit amphibian conservation globally.Read moreRead less
