Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine ....Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine how evolution works at the DNA level. This proposal will determine if animals that develop identical skull shapes, also show identical changes in their DNA. The findings will define new developmental genes and explain how selection, adaptation and evolution works at the DNA level. Read moreRead less
Interplay between mechanical and biological microenvironments in chondrocyte function: towards an understanding of cartilage pathology. This project will develop state-of-the-art laboratory models of healthy and diseased joints. These models will assist in answering questions about the causes of osteoarthritis, and provide information on how best to treat diseased joints.
Regenerating articular cartilage with smart hydrogels and fabrication technologies. Osteoarthritis affects over 1.6 million Australians and a cure remains elusive. Tissue engineering promises to regenerate joints, but issues with tissue quality, organisation and cost have led to limited clinical application. This project will develop new tissue fabrication technologies to engineer cartilage with appropriate organisation and lower costs.
Calcium signalling by intracellular calcium stores in rabbit, mouse and man: implications for muscle performance and athletic ability. This project addresses essential vital life functions such as respiration and movement and factors that determine whether muscles are better suited to weight lifting, endurance or sprint activities. The outcome will fill an information gap and provide therapeutic targets, significant in medicine, sports and veterinary science.
Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It ....Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It will bear upon the phylogeny of flightlessness among birds. It also has potential implications for studying human limb deformities. Overall, the project will enhance our understanding of how genes control the great diversity that we see in nature.Read moreRead less
The role of muscle and tendon mechanics in human muscle damage. This project aims to examine what sort of forceful stretch is required to cause exercise induced muscle damage (EIMD) in humans and how muscles adapt to limit future damage. Specifically, the project aims to examine how the elastic properties of tendons might reduce muscle damage by buffering stretch in muscle fibres. Using cutting-edge ultrasound imaging technology, human muscle strain in different regions of muscle will be examine ....The role of muscle and tendon mechanics in human muscle damage. This project aims to examine what sort of forceful stretch is required to cause exercise induced muscle damage (EIMD) in humans and how muscles adapt to limit future damage. Specifically, the project aims to examine how the elastic properties of tendons might reduce muscle damage by buffering stretch in muscle fibres. Using cutting-edge ultrasound imaging technology, human muscle strain in different regions of muscle will be examined to quantify the temporal relationship between muscle power absorption and EIMD. The importance of muscle and tendon mechanical properties in buffering the muscle from potential damage will be gauged. This could be a critical mechanism for preventing EIMD in exercising humans.Read moreRead less
Angiogenic defects in mutant growth plate cartilage reveal new modulators of vascular invasion. Converting cartilage to bone requires blood vessel invasion from the bony interface. This project will test, in vitro and in vivo, the hypothesis that collagen fragments regulate blood vessel invasion into cartilage. This data will have implications for processes requiring new blood vessels such as bone growth, cancer, inflammation and ischemia.

Summary
How T cells modulate stem cells and tissue regeneration. The project aims to determine how T cells modulate tissue repair and regeneration in mammals. Most of the mechanisms modulating the healing of tissues are elusive. This research is expected to reveal unknown mechanisms controlling the processes of tissue repair and regeneration, particularly the nexus between the stem cells involved in the tissue healing process and the immune response .
The grand challenge of predicting human movement energetics. This Project aims to advance our understanding of how the neuromuscular system uses energy during movement by exploring the interplay of different factors that influence movement energetics. The Project will explore different levels of organisation; from how muscle fibres consume energy to how those fibres interact and are subsequently controlled within a complex neuromuscular system. Expected outcomes of this Project will be an improv ....The grand challenge of predicting human movement energetics. This Project aims to advance our understanding of how the neuromuscular system uses energy during movement by exploring the interplay of different factors that influence movement energetics. The Project will explore different levels of organisation; from how muscle fibres consume energy to how those fibres interact and are subsequently controlled within a complex neuromuscular system. Expected outcomes of this Project will be an improved capacity to predict energy expenditure of the vast array of movements that humans perform. This will enable accurate monitoring of human energy expenditure and will provide benefits for individualised exercise prescription, enhancing work productivity or designing devices to augment human performance.Read moreRead less

This project aims to develop a platform for quantitative 3-D imaging of cell elasticity in tissue which may make possible new discoveries in cell mechanics. Mechanical properties, in concert with chemical properties, act to determine the function and behaviour of cells, and play a vital role in diseases such as cancer. Measurement of the mechanical properties of the cell in its native tissue environment, currently not possible, could accelerate the understanding of cell mechanics. This project plans to develop in vivo mechano-microscopy by combining innovations in optical microscopy, micro-mechanical loading, and computational methods. It then plans to demonstrate its capability by producing the first 3-D elasticity maps of skeletal muscle cells in living animals.Read moreRead less
