The deaths of newborn infants account for 46 per cent of all deaths in children under five, with the majority (75 per cent) occurring within the first week of life and around 50 per cent of these dying within 24 hours of birth. Birth is a stage of considerable vulnerability, as the newborn’s physiology must undergo remarkable changes allowing it to transition its existence from an aqueous to a gaseous environment independent from its mother. This project is focused on providing a better understanding of the transition to newborn life. The knowledge gained will be used to develop more effective approaches for managing infants at birth. In particular, Prof Hooper’s team will develop a neonatal version of ‘precision medicine’, targeting care to the specific needs and requirements of the infants as they transition to newborn life.

Disorders of sex development (intersex conditions) and gender dysphoria (transsex) can be traumatic in children and adults and require ongoing endocrine, surgical and psychosocial care. Dr Harley is studying the genetics of these conditions to improve patient management. He has also uncovered completely unexpected roles for male sex determining gene SRY in the male brain and will test his novel SRY-based disease-modifying therapy in a first-in-human clinical trial on men with Parkinson’s disease.

Colon cancer is one of the top three cancers in Australia in both incidence and mortality. One of the main challenges in colorectal cancer is the lack of targeted therapies. This is because the main genetic driver in this cancer, b-catenin, is a transcription factor which cannot be easily treated with drugs. Using a diverse set of tools that we’ve generated such as mouse genetic models, drug screens, whole genome CRISPR screens, and clinical patient material, Associate Professor Firestein is progressing promising therapeutic targets and biomarkers. This Research Fellowship will support scientific studies to identify the key genetic regulators of b-catenin and progress new therapeutic opportunities to the clinic.

Regenerative medicine has been heralded as the next wave of medical advancement. The realisation of this promise requires an integrated approach to operationalising manufacturing capabilities, commercialising and obtaining regulatory approval for market entry of regenerative medicine.  Dr Lim’s vision is to increase patient accessibility by addressing technological and manufacturing challenges to expedite regulatory approval and reduce costs of treatments.  She will be working with Australian biotech companies, Scinogy Pty Ltd and Cell Therapies Pty Ltd, to traverse the translational valleys.

Brain injury and long-term neurodevelopmental disability in preterm babies remains high – more than 7000 preterm babies born each year in Australia require intensive care. Many clinical practices in the neonatal intensive care unit (NICU) have been adopted from adult or paediatric treatments and are not specific for preterm infants. Associate Professor Wong will interrogate the effects of clinical treatments used in the NICU on brain oxygen delivery and neuropathy in the preterm brain. The research will inform clinicians when choosing the appropriate interventions for protecting the vulnerable preterm brain.

Dr Forster’s research group is focused on the role played by the complex microbial communities that exist throughout our bodies. The group aims to elucidate how these microbes contribute to our health and explore how they can cause or exacerbate numerous immune related diseases. Through this Fellowship, Dr Forster will work with his research group to apply this knowledge and develop methods to modify the microbial communities as a therapeutic option for disease prevention and cure.

Preterm babies exposed to inflammation during pregnancy have a high incidence of breathing difficulties and brain injury, which often lead to cerebral palsy. Dr Stojanovska’s research aims to investigate whether inflammation injures the fetal brainstem – a life-sustaining brain region which controls our breathing, and whether anti-inflammatory treatments can protect against this injury. Outcomes of this work will guide clinical trials focused on reducing the burden of preterm brain injury.

This study will provide strong evidence of the usefulness of a simple blood test to predict the likelihood of a successful IVF embryo transfer.  Blood samples from IVF centres in Australia and Singapore will be collected and used to assess the reliability of a previously developed serum signature in predicting the outcome of embryo transfer. This will aid clinical decision-making in the treatment of infertile women, improve IVF success rates and reduce both financial and emotional costs.
