Summary
Fortifying animal and plant germ cells against proteotoxic stress. Cellular stress is responsible for widespread inefficiencies in plant and animal reproduction. Using high resolution proteomics and cryo-electron microscopy, this project aims to investigate how plant and animal germ cells respond to environmental stresses that are known to disrupt fertility, and assess two novel strategies to decrease the sensitivity of cells to stress.

Cellular stress is responsible for widespread inefficiencies in plant and animal reproduction. Using high resolution proteomics and cryo-electron microscopy, this project aims to investigate how plant and animal germ cells respond to environmental stresses that are known to disrupt fertility, and assess two novel strategies to decrease the sensitivity of cells to stress. This project is expected to generate new global knowledge in the area of fertility regulation with the potential to improve the tolerance of crop species to heat stress, prevent economic losses and help to secure future food production. Further, this project has the intended benefit of improving the fertility of animal species that suffer from stress-induced infertility.

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.

Inflammation as an early form of maternal-fetal signalling in pregnancy. The project aims to understand the role of inflammatory signalling in marsupial pregnancy. This project is expected to explain why inflammation, a processes normally confined to injury and infection, is a part of reproduction in live-bearing mammals. Outcomes of this project include robust measures of the capacity for, impact of, and evolution of, inflammatory signalling in marsupial pregnancy. The project will provide new ....Inflammation as an early form of maternal-fetal signalling in pregnancy. The project aims to understand the role of inflammatory signalling in marsupial pregnancy.

Outcomes of this project include robust measures of the capacity for, impact of, and evolution of, inflammatory signalling in marsupial pregnancy. The project will provide new knowledge about the unique biology of Australia's marsupial fauna.This project will provide significant benefits, including enhanced capacity for reproduction research in Australia, new international collaborations between Melbourne and Yale, and a new explanation for the puzzling role of inflammation in pregnancy.Read moreRead less

Summary
Determining the regulation of ovary development with single cell sequencing. This project will greatly advance our understanding of ovary development and mammalian reproduction. I will investigate the process of ovarian primordial follicle activation including its genetic regulation, the importance of supportive granulosa cells and the biological significance of regulatory factors.

This project will greatly advance our understanding of ovary development and mammalian reproduction. I will investigate the process of ovarian primordial follicle activation including its genetic regulation, the importance of supportive granulosa cells and the biological significance of regulatory factors. This will be achieved through the comprehensive investigation of a single cell transcriptomic dataset of ovarian development (Aim 1) in conjunction with functional studies (Aim 2). The outcomes of which will hold significant benefit to animal reproduction through new strategies to improve livestock productivity and control invasive pest species. These outcomes are of economic and environmental and benefit nationally.Read moreRead less

Banking on spermatogonial stem cells to safeguard Australian native fauna. Spermatogonial stem cells in the testis are an untapped resource for species conservation. This project aims to characterise metabolic pathways that control spermatogonial stem cell function, and define the conserved nature of these pathways between model species (mouse) and vulnerable Australian native fauna.

Spermatogonial stem cells in the testis are an untapped resource for species conservation. This project aims to characterise metabolic pathways that control spermatogonial stem cell function, and define the conserved nature of these pathways between model species (mouse) and vulnerable Australian native fauna. Expected outcomes of this project include an enhanced capacity to culture koala spermatogonia in vitro, which will be a first step towards using spermatogonial biobanking as a tool to maintain genetic diversity in this species. Outcomes from this study should provide significant benefits in safeguarding our unique Australian native species, which is of particular importance following the catastrophic 2019/20 bushfire season.Read moreRead less

This project aims to address the global biodiversity crisis by incorporating evolutionary theory into the study of reproductive technologies. With 41% of amphibian species now threatened with extinction, this project expects to revolutionise the field, enhancing the propagation and genetic management of threatened amphibians. Specifically, incorporating evolutionary theory into the study of amphibian reproductive technologies will increase our capacity to predict spermiation responses and identify parental-genetic incompatibilities that may compromise offspring viability. Ultimately, this novel approach will provide significant benefits by fast-tracking the development of reproductive technologies for threatened species recovery.Read moreRead less
