Closing the loop between salience and brain activity. This project aims to understand how animals exposed to an abundance of highly complex information decide what to attend to, that is, how they determine visual saliency. The project will approach this question by systematically tracking visual decision-making in the smallest animal brains, in closed-loop virtual reality environment. This approach will uncover basic working principles applicable to any system that needs to pay attention in a vi ....Closing the loop between salience and brain activity. This project aims to understand how animals exposed to an abundance of highly complex information decide what to attend to, that is, how they determine visual saliency. The project will approach this question by systematically tracking visual decision-making in the smallest animal brains, in closed-loop virtual reality environment. This approach will uncover basic working principles applicable to any system that needs to pay attention in a visually cluttered world, from insects to humans or autonomous vehicles.Read moreRead less
Visual guidance of flight in birds. Birds flying rapidly amidst the branches of trees engage continually in a three-dimensional slalom. This project will study birds flying through tunnels and gaps, to understand how they use their eyes and wings to achieve this agility. The results could suggest better designs for unmanned aerial vehicles operating in dense urban environments.
Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control ....Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control pursuit. The resulting algorithms will be incorporated into unmanned aerial vehicles for detecting, monitoring and tracking other objects in the sky, and their performance will be evaluated. The results will provide a better understanding of the biological basis of pursuit behaviour, as well as lead to novel technologies for aerial surveillance and safety.Read moreRead less
Strategies for mid-air collision avoidance in aircraft: lessons from bird flight. Birds seldom collide with each other and other objects, despite the high speeds at which they fly in complex environments. This project will examine how birds sense and avoid impending collisions, and will use these results to design novel strategies for the detection and avoidance of aircraft mid-air collisions.
A contractile cochlear frame - a possible new mechanism of sound adaptation. It is generally accepted that the rigid frame that harbours sensory structures in the hearing organs of modern higher vertebrates has only a passive supporting role. We have discovered a contractile component in the cartilaginous cochlear frame of the lizard Teratoscincus scincus and demonstrated that the tonus of the contractile tissue can be regulated. We hypothesize a new, previously unknown mechanism of slow mechani ....A contractile cochlear frame - a possible new mechanism of sound adaptation. It is generally accepted that the rigid frame that harbours sensory structures in the hearing organs of modern higher vertebrates has only a passive supporting role. We have discovered a contractile component in the cartilaginous cochlear frame of the lizard Teratoscincus scincus and demonstrated that the tonus of the contractile tissue can be regulated. We hypothesize a new, previously unknown mechanism of slow mechanical adaptation in the vertebrate hearing organ. The aim of the proposed project is to examine this hypothesis in more detail.

Plasticity in the periphery: how sensory experience modulates the sense of smell. This project will investigate how sensory experience modulates the molecular and neural mechanisms underlying the sense of smell. The outcomes will help us understand the phenomenon why scent perception changes throughout life, and illuminate how exposure to odours in the daily environment can modulate the sense of smell.
Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psycholo ....Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psychological conditions, including attention deficit disorder, autism, and schizophrenia, which have major social and economic costs in Australia. Therefore, by expanding our understanding of how attention operates at the level of neurons, we can begin to develop targeted treatments for addressing these conditions. Read moreRead less
Deep Downunder: designing a deep-sea exploration and discovery capability for Australia. Exploration of the deep-sea with the modern technologies to be developed by Deep-Downunder is a first for Australia. We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on ....Deep Downunder: designing a deep-sea exploration and discovery capability for Australia.

We aim to explore and discover life at depths from 50-3000m off The Great Barrier Reef, around the seamounts of Lord Howe Island and Tasmania and in the deep canyons of WA and SA. We expect to discover new species, hope for a glimpse of giant squid at home and will answer specific questions on Australia's ocean biology, fisheries and biotechnology never before approachable. To be effective guardians of Australian waters we must learn what lies in the depths we can't see from a boat.Read moreRead less

This project aims to reveal how the visual systems of marine creatures from the Great Barrier Reef receive and interpret colour and polarisation information, much of which is invisible to the human eye. It aims to utilise this data to tackle fundamental questions in neuroscience and inform bio-inspired camera design and machine-vision solutions. The resulting new generation of polarisation cameras will be used to characterise the environments, animals and brains that inspired them in the first place. This will help the understanding of how nervous systems convey information and may improve our ability to detect dysfunction in neurons and other cells.Read moreRead less
New dimensions in colour and polarisation vision on The Great Barrier Reef. Many animals possess colour vision that outperforms humans and some also have a type of vision we lack altogether, polarisation vision. By comparing design and discovering strategies from the sensory systems of animals on The Great Barrier Reef, the project will enhance our knowledge of their sensory world, their ecosystem and broader visual neuroscience.
