Why do only some exotics become invasive? Combining ecological and genomic approaches to address alternative hypotheses in a recent Australian weed. This project will specifically test alternative hypotheses about how weeds become invasive.

Combining ecological and genomic approaches to address alternative hypotheses in a recent Australian weed. This project will specifically test alternative hypotheses about how weeds become invasive. As invasive weeds affect both agricultural and native ecosystems equally, research on understanding the mechanisms of weed invasion is critical. Outcomes will benefit Australia by allowing better prioritisation of management against exotic plants already in the country by providing predictive tools to estimate likelihood of spread. For formal Pest Risk Analysis by regulators (eg Biosecurity Australia), our project will provide genomic tools by which the potential weediness of a regulated plant can be assessed through genetic screening, and forms part of an international effort to identify 'weedy genes'.

Defining the earliest events in lymphatic vasculature formation from veins. Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo.

Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo. The project aims to utilise zebrafish and mouse embryos to greatly expand knowledge in the formation of this essential vertebrate tissue. Ultimately, this is expected to provide new knowledge in stem and precursor cell differentiation, the evolution of complex organ systems and tissue formation. Outcomes may impact on future biotechnology in the areas of tissues engineering, stem cell differentiation and regeneration.Read moreRead less

Solar-thermal desalination system for parallel water-electricity generation. This project aims to develop a multi-functional solar-thermal desalination device to simultaneously produce clean water and electricity. Interfacial solar evaporation-based desalination technology has the unique advantage of using solar light as the sole energy source for affordable clean water production.

This project aims to develop a multi-functional solar-thermal desalination device to simultaneously produce clean water and electricity. Interfacial solar evaporation-based desalination technology has the unique advantage of using solar light as the sole energy source for affordable clean water production. However, its absolute evaporation rate is still too low for practical application and all of the latent heat released from vapor condensation during desalination is wasted. Solving these two critical issues by the study of energy nexus, design and fabrication of advanced photothermal materials and desalination devices could accelerate practical adoption of this technology and benefit millions of people who desperately need clean water.

This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understanding of how decision-making evolves in healthy ageing, and a tool based on genetic scores and computational modelling to predict an individual's trajectory of cognitive function. This could help identify individuals who are at risk for cognitive decline, which could then inform better interventions.Read moreRead less
Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the ....Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the techniques of cognitive neuroscience, the project aims to provide a better understanding of the cognitive and neural mechanisms that govern attention in an applied setting. It expects to identify the factors that exacerbate lapses in attention and collisions. The effect of everyday impediments such as mobile phones, alcohol and fatigue will be investigated together with means of minimising these attentional lapses and improving safety.Read moreRead less
