Summary
How does muscle grow and repair after injury or disease? This basic question in the focus of the research in this fellowship. Specific cells are put aside during development to generate the growth and provide stem cells required for regeneration. Using the advantages of the zebrafish system I will record the action of different stem cell populations during growth and disease. I will define the genes required for stem cell action and utilize this knowledge to create new therapeutic pathways.
We will apply genome-wide approaches to identify the gene networks that regulate the self-renewal and the differentiation of muscle stem cells and their fusion to muscle fibres. These studies will deliver the first characterisation of the molecules and pathways implicated in these processes, which are essential steps of muscle growth.
I am a physiologist investigating the molecular basis of normal function in skeletal muscle and the dysfunctions occurring in various muscle diseases and in fatigue. In addition, I investigate analogous dysfunction of calcium release and excitability occu

Summary
Inherited skeletal dystrophies and myopathies are devastating and debilitating disease for which there are no cures and general muscle wasting is major health problem for a significant number of older Australians. Understanding how muscles form, grow and are maintained in model system, the Zebrafish, will provide avenues for treatment of these diseases. We will create models of human muscle diseases in zebrafish and test the usefulness of different therapeutic approaches we develop.

Summary
The focus of my research is to investigate the cellular mechanisms underlying regulation of skeletal muscle size and function in health and disease. By defining these processes we can establish the events contributing to muscle wasting and frailty commonly associated with serious illness and advancing age, and develop interventions to prevent/overcome this important contributor to poor health prospects and reduced survival.
We aim to grow body tissues for surgery, including heart muscle, liver and pancreatic islets (for diabetes) and will investigate using stem cells to repair the brain after stroke. We will attempt to boost the expansion of blood vessels in growing tissues using molecular tools we have found crucial for cell signaling. In growing heart tissues and in stroke we will improve drugs that might boost the potential of stem cells to regenerate damaged tissues
Axonal Regeneration And Degeneration: Cellular And Molecular Mechanisms

Summary
Understanding how to repair of nerve damage following a traumatic injury, a vascular accident, or a degenerative condition, is essential to develop novel effective treatments. We have identified, in a simple genetic model system, the molecular mechanisms that allow a transected nerve to be repaired by reattachment of its two separated fragments. This 'axonal fusion' process is a highly promising innovative approach that can be exploited to restore the original neuronal circuit.
Prof. Herbert conducts clinical research into the effectiveness of physiotherapy interventions. A focus of this research is study of the effectiveness of stretch-based interventions for prevention and treatment of contracture. His clinical research is backed by a program of laboratory research investigating the mechanical properties of human muscles.

Summary
Heart failure (HF) is a common cardiovascular problem which causes disabling symptoms and reduces life expectancy. HF is the commonest cause or contributor to hospitalization in people over 65 years. For patients with advanced HF, survival is worse than that for aggresive cancers. At present, for patients with advanced HF and its complications, there are very few treatment options. Over the next 5 years I will conduct a comprehensive series of studies in animal models and in patients to develop ....Heart failure (HF) is a common cardiovascular problem which causes disabling symptoms and reduces life expectancy.
