Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blo ....Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blood flow and the exchange of expertise between leading researchers in Australia and Canada. In the long-term, this will enhance Australia’s research capacity in fetal physiology and may lead to new tools for monitoring or supporting fetal development.Read moreRead less
Quantifying yeast cell mechanisms: filamentous growth and biofilm formation. This project aims to quantify the cellular mechanisms of yeast growth to advance our understanding of these organisms and support strategies to prevent and treat disease. Although yeasts are some of the most studied organisms in biology, their modes of filamentous growth and biofilm formation are not fully understood. Yeasts such as the Candida species cause potentially lethal infections through filamentous invasion of ....Quantifying yeast cell mechanisms: filamentous growth and biofilm formation. This project aims to quantify the cellular mechanisms of yeast growth to advance our understanding of these organisms and support strategies to prevent and treat disease. Although yeasts are some of the most studied organisms in biology, their modes of filamentous growth and biofilm formation are not fully understood. Yeasts such as the Candida species cause potentially lethal infections through filamentous invasion of tissues. The project plans to develop methods to quantify the mechanisms driving these growth processes. These methods will be designed to permit classification and selection of strain-specific properties of yeasts, providing a deeper understanding of the mechanisms controlling cellular and colonial morphology in the growth of Saccharomyces cerevisiae, the most important yeast in both biotechnology and bioscience.Read moreRead less

This project will define a novel, and essential, pathway for male fertility and may ultimately have relevance to the maintenance of health or improving fertility.
TREX-mediated nuclear mRNA export in neuronal differentiation and function. This project aims to study nucleus-to-cytoplasm information flow and the cellular toolbox required for this process. To ensure competitive growth and survival, plant and animal cells have sophisticated mechanisms of information transfer. One such process is efficient export of molecules from the cell nucleus (the coding space) to the cell cytoplasm (the protein synthesis space). This project will use a cell-based system ....TREX-mediated nuclear mRNA export in neuronal differentiation and function. This project aims to study nucleus-to-cytoplasm information flow and the cellular toolbox required for this process. To ensure competitive growth and survival, plant and animal cells have sophisticated mechanisms of information transfer. One such process is efficient export of molecules from the cell nucleus (the coding space) to the cell cytoplasm (the protein synthesis space). This project will use a cell-based system that can precisely control different aspects of the toolbox performance to understand this process. The knowledge and resources generated can be used to develop products or services with tangible economic and health benefits.Read moreRead less
Cell death by self-eating: Autophagy-dependent tissue removal. This project aims to study the mechanisms and regulation of autophagy-dependent cell death. Cell death maintains cell and tissue homeostasis. Although most cell death is mediated by apoptosis, other modes of cell deletion have emerged recently. One form of cell death involves autophagy, the catabolic process of cellular self-digestion through lysosomal enzymes. As autophagy is a default mechanism of cell survival under stress, the id ....Cell death by self-eating: Autophagy-dependent tissue removal. This project aims to study the mechanisms and regulation of autophagy-dependent cell death. Cell death maintains cell and tissue homeostasis. Although most cell death is mediated by apoptosis, other modes of cell deletion have emerged recently. One form of cell death involves autophagy, the catabolic process of cellular self-digestion through lysosomal enzymes. As autophagy is a default mechanism of cell survival under stress, the idea of autophagy-dependent cell death has been controversial. This proposal aims to resolve this question and provide highly topical knowledge of broad biological significance.Read moreRead less
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 fun ....Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 function in the testes including stem versus progenitor cell activity and genome-wide target gene regulation. These studies will uncover the molecular and cellular mechanism by which SOX3 controls spermatogenesis and provide unique insight into how a single TF controls context-dependent differentiation in sperm versus brain progenitor cells.Read moreRead less
How Scientific Theories are Confirmed: A History of Atomic Theories of Matter. This project addresses the question of how scientific theories are confirmed by experiment - a fundamentally important aspect of philosophy of science and science itself - that has yet to be definitively answered.

This project challenges the standard narrative of women in the 1950s through a study of the intersections of higher education, gender and place. By studying women graduates in Australia and the United States within the context of demographic, employment and cultural change, it develops life histories of graduate women over several decades of their post-universtiy lives, drawing on comparative sources. It offers a new framework for women's educational history, one that goes beyond access and focuses on the new identities that were formed as graduate women negotiated the contradictions of higher education and the dominant femininity of the period.Read moreRead less
