Summary
Casual Fertility Consequences: The Role of Non-Standard Employment (NSE). This project aims to investigate the role of temporary, casual, part-time paid work (non-standard employment) on Australians’ fertility behaviour (childbirth intentions and outcomes). It expects to use high-quality longitudinal data, engage in novel quasi-experiments (policy changes) to identify new causal mechanisms and pathways between employment types and fertility. Expected outcomes include a novel interdisciplinary th ....Casual Fertility Consequences: The Role of Non-Standard Employment (NSE). This project aims to investigate the role of temporary, casual, part-time paid work (non-standard employment) on Australians’ fertility behaviour (childbirth intentions and outcomes). It expects to use high-quality longitudinal data, engage in novel quasi-experiments (policy changes) to identify new causal mechanisms and pathways between employment types and fertility. Expected outcomes include a novel interdisciplinary theoretical framework, most up-to-date empirical evidence on this topic in Australia, high-quality research outputs and training, and clear work and family policy recommendations. This should significantly benefit families, communities, governments and organisations to lift productivity. Read moreRead less
Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion o ....Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less
Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This k ....Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This knowledge will reveal how IPO5 controls formation of sperm by revealing what other proteins it binds to and how this affects cell signaling and responses to the environment.
Benefits: This will provide information about potential interventions to control fertility or to repair abnormal cells.

Sperm ciliary gating and midpiece formation – a novel player and process. We have identified CCDC112 an essential player in mammalian sperm tail development and male fertility. This project aims to define the role of CCDC112 in 1) the formation of the core to the sperm tail, the axoneme, and 2) the packaging of mitochondria into the midpiece. Within this Discovery Project we will define the mechanism(s) of CCDC112 functions and the consequences of its dysfunction. Insights from this grant will b ....Sperm ciliary gating and midpiece formation – a novel player and process.

Within this Discovery Project we will define the mechanism(s) of CCDC112 functions and the consequences of its dysfunction. Insights from this grant will be of significance to fertility across mammals and may ultimately benefit the selection of highly fertile males within the agricultural sector.Read moreRead less
Decoding microtubule remodelling in sperm production. All eukaryotic cells possess a dynamic microtubule (MT) cytoskeleton, which requires constant remodelling to satisfy its many essential cellular roles. Emerging data suggests modifications to the MT surface (the tubulin code) may act as instructional signposts for remodelling. This project aims to define a fundamental component of the tubulin code, glutamylation, and define how this directs MT severing. It also aims to define the cellular fun ....Decoding microtubule remodelling in sperm production. All eukaryotic cells possess a dynamic microtubule (MT) cytoskeleton, which requires constant remodelling to satisfy its many essential cellular roles. Emerging data suggests modifications to the MT surface (the tubulin code) may act as instructional signposts for remodelling. This project aims to define a fundamental component of the tubulin code, glutamylation, and define how this directs MT severing. It also aims to define the cellular functions of MT-severing enzyme FIGNL1 and key MT glutamylation enzymes (CCP1, CCP5 and TTLL1). Insights will be generated using sperm production as a model system and will thus inform the mechanisms by which fertile sperm are built, in addition to being relevant to cell biology across eukaryotic species.

RNA combines the information content of DNA and the physical properties of proteins. These features mean it's emerging as a major player for new knowledge; for answers to fundamental questions in biology, and for applications in biotechnology. This project aims to understand how non-canonical RNA processing events control gene expression. How mRNA is processed post-transcriptionally for selective storage, translation, stabilisation or decay to control development. RNA-driven processes program morphogenesis and differentiation of spermatids, but via mechanisms only poorly understood. Uncovering the function of extensive cytoplasmic polyadenylation, which is essential for murine fertility, may fuel the next wave of RNA biotech applications. Read moreRead less
