Activity-induced gene expression is central to neural plasticity, learning, and memory; however, the underlying mechanisms of these processes in the brain have yet to be fully resolved. The aim of this proposal is to obtain a deeper understanding of the functional relationship between genes and brain function. By elucidating the full repertoire of epigenetic mechanisms in the brain during learning and the formation of memory, it is hoped that the true nature of brain adaptation across the lifespan will be revealed. Findings which may then provide new opportunities to strengthen, maintain and optimise cognitive function.Read moreRead less

Investigations into the antibacterial mechanism of action of cannabidiol. Cannabidiol (CBD) comes from a set of naturally occurring compounds, with a range of applications in mainstream culture. We have recently reported that CBD has excellent antimicrobial properties, with the ability to kill bacteria. This project aims to understand how CBD works by examining CBD-bacterial interactions at a genetic and molecular level.

Cannabidiol (CBD) comes from a set of naturally occurring compounds, with a range of applications in mainstream culture. We have recently reported that CBD has excellent antimicrobial properties, with the ability to kill bacteria. This project aims to understand how CBD works by examining CBD-bacterial interactions at a genetic and molecular level. By understanding how CBD acts on and within bacterial cells, we can create fundamental new knowledge that could lead to the design of improved analogs of CBD to that can treat bacterial infections. As a much-needed completely new antibiotic class, this will lead to significant benefits, supporting Australia's National Strategy to combat the challenges posed by antimicrobial resistance.Read moreRead less

This should lead to significant benefits, including high impact publications, additional collaborations with industrial partner Botanix, and a new class of antibiotics to overcome antibiotic resistance.Read moreRead less
Decoding miRNA regulated genetic circuits. This project will aim to develop a much better understanding of how the process of making proteins from genes is regulated, and will develop scientific software capable of predicting how a cell will respond to changes in this regulation. The results will have widespread use, including assistance in deciding the best treatments for genetic diseases.
Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined wit ....Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined with innovative analysis, we propose to define and validate each cell state at the molecular level.
This new knowledge would greatly enhance our ability to control the transition between cell states leading to a more widespread use of endothelial cells in bioengineering of tissues globally for many applications.

This project aims to develop novel bioinformatics methods for single cell transcriptomic data that seek to model variability in cell populations. The project expects to generate new approaches using Bayesian statistics that will act as high-end enablers of discovery in transcriptional regulatory processes. Through an interdisciplinary combination of experimental and computational research, insights into fundamental biological processes will be elucidated, specifically the robustness of cellular systems. Expected outcomes include a suite of novel tools that will push the boundaries of current bioinformatics solutions with potential to deliver significant benefits to every domain of biological science, particularly tissue engineering and synthetic biology.Read moreRead less
A macrophage-centric holistic view of postnatal development. The immediate postnatal period in mammals is crucial for survival, long term health and productivity. It is also a time when animals are especially susceptible to infectious disease.

The immediate postnatal period in mammals is crucial for survival, long term health and productivity. It is also a time when animals are especially susceptible to infectious disease. This project aims to investigate how cells of the innate immune system called macrophages control somatic growth and development of mature organ function in the early postnatal period. The project aims to build upon investment in new animal models and a novel discovery to generate significant new knowledge that challenges current concepts of mammalian growth control. The outcomes will enhance Australia's international reputation in the fields of physiology, immunology and developmental biology and may translate to improvements in health in animals and humans.

How do mammalian germ cells transition from mitosis to meiosis? This project aims to determine how germ cells are regulated in the mammalian embryo. Germ cells go on to form the sperm and eggs and are, therefore, critical for reproduction. In particular, this project expects to generate new knowledge about the process of meiosis, a cellular process that is specific to the germ cells. Expected outcomes will inform efforts to control fertility and infertility in livestock, humans and other mammali ....How do mammalian germ cells transition from mitosis to meiosis?

In particular, this project expects to generate new knowledge about the process of meiosis, a cellular process that is specific to the germ cells. Expected outcomes will inform efforts to control fertility and infertility in livestock, humans and other mammalian animals (e.g. pets and endangered species). They are also likely to inform the discipline of stem cell biology in general.Read moreRead less
