Urban flood modelling at speed and scale. Frequent floods in urban areas cause damages comparable to extreme floods. This is likely to intensify with future urbanisation and climate change. Although Water Sensitive Urban Design (WSUD) offers sustainable urban drainage solutions, there are no models that can select an optimal WSUD system to deliver on a set urban flood mitigation target. The project aims to develop a new generation of fast urban flood models and the-first-of-its-kind WSUD plannin ....Urban flood modelling at speed and scale. Frequent floods in urban areas cause damages comparable to extreme floods. This is likely to intensify with future urbanisation and climate change. Although Water Sensitive Urban Design (WSUD) offers sustainable urban drainage solutions, there are no models that can select an optimal WSUD system to deliver on a set urban flood mitigation target. The project aims to develop a new generation of fast urban flood models and the-first-of-its-kind WSUD planning tool to support industry and governments to effectively reduce the urban flooding damages. The project outcomes are also applicable for advancing early warning systems and real-time control of floods.Read moreRead less
Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutant ....Electron transport catalysis in organohalide pollutant respiration. This project aims to understand the link between substrate specificity and gene sequence of dehalogenating enzymes in organohalide respiring bacteria (ORB) and the mechanism by which electrons are transferred to dehalogenating enzymes through protein-protein interactions. Organohalides were present in Earth's early history and now pollute the environment globally. Organohalide respiring bacteria (ORB) can degrade these pollutants by using them as terminal electron acceptors in their respiratory metabolism. This represents one of the most ancient respiratory systems on Earth about which little is known. This project will add to our fundamental knowledge of microbial evolution and metabolic systems, and pave the way for next generation organohalide remediation technologies.Read moreRead less
Understanding how bacteria form multicellular biofilm communities on surfaces: the role of cyclic diguanylate as a potent biofilm activator. Bacteria usually exist as multicellular communities called biofilms when attached to surfaces, frequently to the detriment of the environment, industry and health. This project will explore the strategies bacteria use to switch from living as free-floating, individual cells to forming biofilms by studying how bacteria 'switch on' their biofilm genes.

Improved rainfall measurement using mobile phone tower link attenuation. The project aims to use the microwave link data between mobile phone towers to complement the sparse rain gauge network in urban areas, to allow more accurate near-real-time monitoring of rainfall. Accurate near-real-time precipitation data at high resolution are critical to flash flood forecasting in and around Australia's capital cities. Current estimates suffer from the limited availability of rain gauge data in urban ar ....Improved rainfall measurement using mobile phone tower link attenuation. The project aims to use the microwave link data between mobile phone towers to complement the sparse rain gauge network in urban areas, to allow more accurate near-real-time monitoring of rainfall. Accurate near-real-time precipitation data at high resolution are critical to flash flood forecasting in and around Australia's capital cities. Current estimates suffer from the limited availability of rain gauge data in urban areas. However, mobile phone towers abound and the microwave links between them can provide information on rainfall intensity, meaning that these data could be used to supplement the rain gauge data. This project plans to develop the technology to generate precipitation maps using mobile phone network link, rain gauge and weather radar data.Read moreRead less

This project aims to investigate the molecular processes underpinning the degradation of polycyclic aromatic hydrocarbons (PAHs) by bacteria. PAHs are persistent environmental contaminants linked to several human diseases, including cancer. Bacteria capable of degrading PAHs could be used to naturally and effectively reduce environmental PAH loads to below safe levels. The project will apply techniques in functional genomics and biochemistry to help define the ways that PAHs are taken up from the environment by bacteria, their fate within bacterial cells, and the ways that bacteria overcome the inherent toxicity of PAHs. The knowledge generated is expected to enhance our capacity to rationally deploy bacteria for PAH degradation.Read moreRead less
