Summary
Phenotypic plasticity of reef fish vision in a changing world. This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal. Through an innovative approach to understanding colour vision and animal behaviour ....Phenotypic plasticity of reef fish vision in a changing world. This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal. Through an innovative approach to understanding colour vision and animal behaviour, this project expects to advance Australia’s leadership in neuroscience and ecology, while also increasing the capacity for international collaborations. Beyond the scientific benefit, it will create public awareness about an endangered ecosystem, inform reef guardianship and may inspire new sensory technology.Read moreRead less
Action selection in insects: how a microbrain knows what to do. Identifying what to do demands integrating sensory information with our current physiological state and memory of past experience to select the best possible action. This is the action selection problem. Our project aims to discover how tiny insect brains solve this fundamental problem. The project combines neural recordings from animals exploring virtual reality, behavioural analyses and computational modelling. The expected outco ....Action selection in insects: how a microbrain knows what to do. Identifying what to do demands integrating sensory information with our current physiological state and memory of past experience to select the best possible action. This is the action selection problem. Our project aims to discover how tiny insect brains solve this fundamental problem. The project combines neural recordings from animals exploring virtual reality, behavioural analyses and computational modelling. The expected outcome is a new understanding of the brain as an effective behavioural control system. This will benefit systems and comparative neuroscience. Our findings may also inspire solutions for robotic systems that must operate autonomously in remote and challenging environments such as disaster relief or exploration.Read moreRead less
A role for sleep in optimising attention. All animal brains are prediction machines, which allows even tiny flies to effectively navigate complex environments. To predict what will happen next is important for guiding attention, but also for detecting anything surprising. This project aims to understand how prediction is optimized by sleep in Drosophila flies. We aim to use electrophysiology and calcium imaging to map visual prediction error signals across the fly brain, and then determine how g ....A role for sleep in optimising attention. All animal brains are prediction machines, which allows even tiny flies to effectively navigate complex environments. To predict what will happen next is important for guiding attention, but also for detecting anything surprising. This project aims to understand how prediction is optimized by sleep in Drosophila flies. We aim to use electrophysiology and calcium imaging to map visual prediction error signals across the fly brain, and then determine how genetically controlled delivery of sleep regulates the quality and distribution of these signals. This knowledge will benefit our understanding of how brains balance a capacity for prediction versus surprise, by examining how evolution has solved this difficult problem in the smallest brains.Read moreRead less
Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport).

Combining biomechanics and movement ecology of kangaroos and relatives. Kangaroos and their relatives are unique in their body form, hopping gait and by the fact that increased speed does not come at an increased energetic cost. This project aims to build 3D musculoskeletal models to understand how muscles and tendons interact, enabling greater distances to be travelled using less energy. Further, it will use animal tracking devices and machine-learning tools to quantify movements in the wild. T ....Combining biomechanics and movement ecology of kangaroos and relatives.

This project aims to build 3D musculoskeletal models to understand how muscles and tendons interact, enabling greater distances to be travelled using less energy. Further, it will use animal tracking devices and machine-learning tools to quantify movements in the wild. This framework will provide novel insights into how energetics, morphology, and habitat have shaped the evolution of this unique group. This may open doors to a range of future ecological, physiological, and conservation studies and provide biological inspiration for energetically efficient robotic and assistive devices.Read moreRead less

Rethinking the function of the human foot. Human feet are unique in shape and structure, having evolved to allow upright locomotion. Despite their importance, we don’t understand how foot shape and structure facilitates upright locomotion.This DECRA aims to explore the relationship between foot morphology and foot function. I will close a large knowledge gap by applying novel experimental and shape modelling approaches to provide unprecedented insights into human foot function. The primary expected outcome is a detailed understanding of how foot shape and structure influences our ability to walk and run. This research will create a paradigm shift in how we think about feet in the context of human evolution, human athletic performance and athletic footwear design.Read moreRead less
Skin in the game: biomimetics, fitness and the springtail cuticle. This project aims to examine the relationship between cuticle (skin) properties, water balance, and fitness in springtails, key players in soil systems. Springtail cuticles are diverse, responsive, and extremely resistant to wetting by water, alcohol and other substances. Their Australian diversity has not been well explored for biomimetic new materials.

This project aims to examine the relationship between cuticle (skin) properties, water balance, and fitness in springtails, key players in soil systems. Springtail cuticles are diverse, responsive, and extremely resistant to wetting by water, alcohol and other substances. Their Australian diversity has not been well explored for biomimetic new materials. This project expects to explore options for new applications in materials science and engineering by generalising the cuticle structure-function relationship. Expected outcomes are new information to harness for industry the diversity of nature’s self-cleaning, water repellent surfaces. Significant benefits lie in potential new biomimetic manufacturing options.Read moreRead less

This project aims to explain the past and protect the present biodiversity of endangered marsupial mammals such as bilbies and koalas. It will generate new knowledge using an interdisciplinary combination of 3D analysis of skull shape, reflecting a mammal’s ability to feed and sense its surrounds, with the fast-moving fields of marsupial conservation and evolutionary genetics. This will help to anticipate if, and how, changing environments and declining numbers reduce these species’ ability to adapt. Benefits include better information to support improved conservation decisions and identification of genes underlying the evolution of marsupial skull diversity.Read moreRead less
