Summary
Reproductive and pregnancy disorders are common in Australian men and women, with 6% couples seeking infertility services and another 30% experiencing recurrent miscarriage, preeclampsia or preterm birth, often resulting in life-time health problems for children, and sometimes stillbirth. This research will investigate the immune causes of these conditions, and the results will contribute to new health tools, diagnostics and medical treatments to support maternal and infant health.
Decoding tissue-specific components of cereal grain development. This project aims to investigate how barley flowers produce cells that deliver nutrients into developing seeds. This project expects to generate new knowledge through international collaboration and technical improvements in cell biology and genetics, overcoming current methodological limitations to precisely influence seed size, shape and quality, which are traits of agricultural relevance to the Australian cereal industry.

This project expects to generate new knowledge through international collaboration and technical improvements in cell biology and genetics, overcoming current methodological limitations to precisely influence seed size, shape and quality, which are traits of agricultural relevance to the Australian cereal industry. Expected outcomes include strengthened international partnerships, leveraged funding and increased knowledge of plant reproduction. This should provide significant benefits, including upskilled researchers, improved research capacity and genetic targets to optimise seed production in challenging climatic conditions.

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

How mammalian males indirectly control transmission of paternal traits. This project aims to address how environmental insults in males prior to conception are able to modify phenotype of subsequent offspring. This project expects to generate fundamental knowledge in a key biological pathway on how non-genetic factors delivered by sperm at conception are able to program the growth of the developing embryo.The knowledge generated from this project will provide understanding and biological options ....How mammalian males indirectly control transmission of paternal traits.

This project expects to generate fundamental knowledge in a key biological pathway on how non-genetic factors delivered by sperm at conception are able to program the growth of the developing embryo.The knowledge generated from this project will provide understanding and biological options for responding to, and potentially mitigating the impacts of environmental change on the mammalian reproductive system.Read moreRead less
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.

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
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.

Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distribut ....Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distributed network of nodes can create a detailed picture of the surrounding radio-frequency (RF) environment: the nodes can work together to map the “RF weather”. In this project we will design advanced sensing and localisation methods to accurately map the RF spectrum, and then exploit this map in communication system design.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.

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.
