Summary
A number of injuries, including stroke, result in tissue loss. Consequently promoting repair will require restoration of tissue structure, replacement cells and a supportive environment to promote integration of these new cells. This study will engineer and develop novel scaffolds that can replace tissue whilst additionally providing physical and chemical support for newly implanted stem cells. This work will be conducted in an animal model of stroke.
Standardising Protocols For The Differentiation And Integration Of Human Pluripotent Stem Cell-derived Neural Transplants In Parkinson's Disease

Summary
Clinical trials have shown that transplanting dopamine neurons (specific nerve cells) into the brain of Parkinson’s disease patients can improve symptoms. Trials use fetal tissue for implantation, which is unsustainable and highly variable. This proposal will examine stem cells as an alternative. We will establish a reliable protocol to instruct human stem cells to become dopamine neurons, develop methods to select these cells and, examine the integration of these transplanted cells in the brain

Summary
Many obstacles exist for cell transplantation in ParkinsonÍs Disease; namely poor graft survival, restoration of appropriate circuitry and adequate nerve fiber growth from new cells. Using knowledge of how neural circuits are established during fetal development, we will attempt to recapitulate these events following transplantation. Further, we will identify new and novel cues in regulating the connectivity and growth of these nerve fibers.

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Learning deep resilient behaviour for uncertainty-aware autonomy. This research project aims to propose a novel framework for developing uncertainty-aware autonomous systems using deep learning. There are fundamental gaps in our knowledge of deep uncertainty quantification and its application for risk-aware decision making. Novel algorithms will be proposed to reliably generate deep uncertainty estimates with low computational overhead. These estimates will be then exploited by safety-critical s ....Learning deep resilient behaviour for uncertainty-aware autonomy. This research project aims to propose a novel framework for developing uncertainty-aware autonomous systems using deep learning. There are fundamental gaps in our knowledge of deep uncertainty quantification and its application for risk-aware decision making. Novel algorithms will be proposed to reliably generate deep uncertainty estimates with low computational overhead. These estimates will be then exploited by safety-critical systems such as autonomous robots to identify risky actions and avoid catastrophise. Developed algorithms will be implemented on an autonomous robotic system to make it averse to uncertainties. The outcomes will greatly increase reliable telerobotic applications in mining, manufacturing, defence, and health.Read moreRead less
Discovering Patterns using Near Unsupervised Leaning to Support the Quick Detection of New Animal Disease Outbreaks Caused by Viruses. Without the capability to identify and study the vast majority of extant viruses using traditional laboratory techniques, emerging threats to Australian livestock health cannot be efficiently diagnosed or treated.

Without the capability to identify and study the vast majority of extant viruses using traditional laboratory techniques, emerging threats to Australian livestock health cannot be efficiently diagnosed or treated. New approaches based on high-throughput sequencing have recently been developed to study such viruses, but making sense of the sequence data is still a complex problem. Together with the project's Partner Organisations, including YourGene Biosciences Australia and the CSIRO Australian Animal Health Laboratory, this project aims to develop new computational methods to broaden the scope of detection and analysis of unknown viruses, enhancing the capability for research into the causative viral agents of animal diseases.Read moreRead less
A Novel Treatment For Ischemic Stroke: Preclinical Assessment In The Nonhuman Primate

Summary
A major source of repair inhibition after brain injury is debris from dying cells, which contains proteins that hinder repair. This project will examine the expression of these proteins in a clinically-relevant model of ischemic stroke and determine if blocking the effect of these proteins neutralises their repair-inhibiting properties. If successful, there is likelihood that this drug, and method of delivery, could be translated into the human for treatment following an ischemic stroke.

This project aims to address the key deficiencies of driving and flight simulators by developing novel human perception-based motion cueing algorithms (MCAs) and leveraging advanced artificial intelligence techniques. Despite widespread applications, existing motion simulators fail to deliver the most accurate human sensation to the user. This failure is mainly attributable to the inefficiency and inflexibility of MCAs used by simulators. It is expected that this project will significantly increase simulator motion fidelity and eliminate motion sickness. This will have substantial benefits to Australian research communities and industries, particularly where simulators are used for training, performance evaluation and virtual prototyping.Read moreRead less

Summary
Spina bifida and anencephaly are two common human congenital malformations that form part of a wide spectrum of mutations known collectively as neural tube defects (NTDs). Patients with the most severe form of spina bifida have a failure of the vertebral column and skin to close over the spinal cord and therefore suffer from limb paralysis and marked bladder and bowel dysfunction. Infants with anencephaly have an open cranial vault and failure of normal brain development and die within the first ....Spina bifida and anencephaly are two common human congenital malformations that form part of a wide spectrum of mutations known collectively as neural tube defects (NTDs). Patients with the most severe form of spina bifida have a failure of the vertebral column and skin to close over the spinal cord and therefore suffer from limb paralysis and marked bladder and bowel dysfunction. Infants with anencephaly have an open cranial vault and failure of normal brain development and die within the first few hours of life. These abnormalities occur frequently (1-1000 live births) and are a direct result of failure of the neural tube to close during embryogenesis. NTDs are influenced by both environmental and genetic factors. The best characterised environmental factor is the dietary supplement folate, which when administered before conception results in a reduction in the incidence of spina bifida. The genetic complexity is evidenced by the array of mouse genetic mutations that give rise to NTDs. One of these mouse mutations, known as Curly tail (ct), has served as the major animal model of human NTDs. This is because the ct mice are resistant to folate administration (like most of the cases of spina bifida currently seen in patients) and because the mice seem to have normal development in virtually all other organ systems. Ironically, the genetic mutation that causes the curly tail phenotype has remained undiscovered for over 50 years. We have now identified the gene mutated in the curly tail mice. This gene is highly conserved in humans suggesting that it will play a similar role in neural tube development in man. The gene, known as GRHL-3, is a descendant of a fly gene critical for development of the nervous system in that organism. The studies we propose here will examine the developmental pathways involved in normal neural tube closure in mice and humans and will impact on our understanding of these devastating congenital malformations.Read moreRead less
Seizures appear unpredictable and greatly affect the quality of all aspects of life for patients with epilepsy and their carers. New advances in complex systems theory suggest that transitions from normal brain activity to seizures are preceded by measurable changes in the brain’s responses to stimuli, known as critical slowing. Measurement of critical slowing will enable prediction of seizures, providing a warning system, and possibly an opportunity to deliver preventative therapies.
