How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the m ....How human vision separately determines object and scene motion. This project aims to enhance understanding of how people process visual scenes containing multiple moving objects of interest. The project intends to measure human visual performance to determine how the brain processes multiple motion signals simultaneously. Expected outcomes include an increased understanding of how we are able to use an evolving visual scene to distinguish between changes due to self-motion and those due to the motion of multiple moving objects such as crowded city footpaths and busy roads. The results will improve our understanding of failures to see moving objects in challenging viewing conditions (for example, high density traffic), and inform work in the design of autonomous driving and augmented reality display systems.Read moreRead less
Colour vision in marsupials. The ability to distinguish colours is a crucial aspect of vision, providing vital data for sexual selection, predator detection and food acquisition. Studies of mammalian colour vision have largely overlooked marsupials. Our recent investigation of spectral sensitivity in two Australian species revealed a colour discrimination capacity beyond that of placentals (excluding primates), implying disparate evolutionary pressures in the two groups. We will provide the fi ....Colour vision in marsupials. The ability to distinguish colours is a crucial aspect of vision, providing vital data for sexual selection, predator detection and food acquisition. Studies of mammalian colour vision have largely overlooked marsupials. Our recent investigation of spectral sensitivity in two Australian species revealed a colour discrimination capacity beyond that of placentals (excluding primates), implying disparate evolutionary pressures in the two groups. We will provide the first comprehensive description of colour vision in marsupials, studying species with differing rhythmicities, habitats and diets. Wavelength sensitivity and molecular structure of retinal visual pigments will be assessed in relation to evolutionary influences and ecological demands.

Food allergies have emerged as a major public health concern affecting 1 in 10 Australian infants. Hospitals waiting times are in excess of 12-months for specialist services. Recent changes in the environment are driving up rates of food allergy but the mechanisms are unclear. Epigenetics is the science of how the environment influences gene behaviour. This fellowship will address the important and urgent question of how modern environments are changing our genes, leading to food allergy.
Neural plasticity in older adult human vision. This project aims to expand our understanding of age related changes in brain function, specifically plasticity. The project will increase knowledge of the role of an inhibitory neurotransmitter GABA in visual plasticity. Expected outcomes include new knowledge regarding the regulation of brain function in adulthood, enabling future research and planning for societal benefit to older Australia.
Using shape change for object perception: human and artificial vision. This project aims to examine the steps taken by the visual system to code the shape of objects, including those that change shape over time. The project seeks to employ experiments assessing human vision and machine learning techniques to examine these codes and, in particular, focus on the advantages of a system that exaggerates shape change over time. Expected outcomes include an improved shape code based on superior human ....Using shape change for object perception: human and artificial vision. This project aims to examine the steps taken by the visual system to code the shape of objects, including those that change shape over time. The project seeks to employ experiments assessing human vision and machine learning techniques to examine these codes and, in particular, focus on the advantages of a system that exaggerates shape change over time. Expected outcomes include an improved shape code based on superior human performance that can have many applications in automated visual systems. This project can directly benefit the animation industries where the creation of realistic movement of humans and animals remains a computationally intensive challenge.Read moreRead less
Neural metrics for space time and numerosity. What we propose is ground-breaking research. It will increase Australia's international competitiveness is science, expand the knowledge base of brain function and psychology and provide valuable training for research scientists.
Evolution and function of colour vision in mammals. The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity. Understanding species colour discrimination will contribute to protective measures of ....Evolution and function of colour vision in mammals. The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity. Understanding species colour discrimination will contribute to protective measures of Australia's unique fauna, presenting social and economic assets for the local and national community, and will set a standard that should be applied world-wide. Close international links and intellectual exchange will be invaluable to the Australian science community, including students.

Resolving multi-sensory conflict as we age: audio-visual integration and the role of normal and abnormal sensory decline. Australia has an ageing population. Even the healthiest older individuals undergo some deterioration of vision and hearing, however, these senses are almost invariably studied in isolation. The real world is multisensory. This project will enhance our knowledge of how ageing impacts on the interpretation of visual and auditory information regarding the timing and location of ....Resolving multi-sensory conflict as we age: audio-visual integration and the role of normal and abnormal sensory decline. Australia has an ageing population. Even the healthiest older individuals undergo some deterioration of vision and hearing, however, these senses are almost invariably studied in isolation. The real world is multisensory. This project will enhance our knowledge of how ageing impacts on the interpretation of visual and auditory information regarding the timing and location of objects; essential precursors to many real world tasks, for example: driving, interpreting speech, and hazard avoidance. This knowledge is essential for the optimisation of audio-visual environments for the elderly, and for the development of tools to improve performance in the presence of sensory decline due to age-related eye disease.Read moreRead less
Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' t ....Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' to birds since they see colours differently from humans. We will determine bird spectral sensitivities and compare them to the spectral reflectance of wind-farms. We will then develop modifications improving the visibility of wind-farms to birds, thereby reducing fatalities.Read moreRead less

Summary
Australian research has identified serious health consequences arising from the 7 to 10 hours of daily sitting that most people do, especially in relation to ‘diseases of inactivity’ – type 2 diabetes, coronary heart disease and breast and colon cancer – that are an unwelcome burden on individuals, families and health systems. This new research examines the practical feasibility and the preventive-health benefits of changing children’s and adults’ sitting time in schools, workplaces and the home ....Australian research has identified serious health consequences arising from the 7 to 10 hours of daily sitting that most people do, especially in relation to ‘diseases of inactivity’ – type 2 diabetes, coronary heart disease and breast and colon cancer – that are an unwelcome burden on individuals, families and health systems.
