The systems biology of stem cells. Using new bioinformatic methods, this project aims to identify new classifiers of different stem cell populations, develop statistical models that address population heterogeneity and provide molecular predictors of the differentiation potential of stem cells. Understanding, predicting and directing the processes of differentiation are major goals in the disciplines of stem cell biology, developmental biology, tissue engineering and regenerative medicine.

Using new bioinformatic methods, this project aims to identify new classifiers of different stem cell populations, develop statistical models that address population heterogeneity and provide molecular predictors of the differentiation potential of stem cells. Understanding, predicting and directing the processes of differentiation are major goals in the disciplines of stem cell biology, developmental biology, tissue engineering and regenerative medicine. Molecular atlas projects have successfully revealed rules of genome output and regulation, by mining patterns that are evident across multiple cell types and datasets. By applying this philosophy to relevant, well-curated stem cell experiments, this project aims to create new methods for the integration and interrogation of smaller individual datasets. These methods should have broad utility and enable new avenues in tissue engineering.Read moreRead less
Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity ....Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity, insulin resistance and various forms of cancers is well established) are leading to a rapid increase in new cancer cases, thus driving a rapid increase in demand for better treatments. This is particularly relevant in Indigenous health where obesity is on the rise following the transition from a traditional to an urban lifestyle.Read moreRead less
Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the cr ....Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the crosstalk between organelles and the cytoskeleton. To date, the role of microtubules remains elusive. Using interdisciplinary approaches combining advanced imaging technology with novel cell biology methods, the project aims to uncover fundamental knowledge about how cells interact with their environment.Read moreRead less
The role of human single-stranded binding protein (hSSB1) in DNA damage repair and tumorogenesis. Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication. This research project aims t ....The role of human single-stranded binding protein (hSSB1) in DNA damage repair and tumorogenesis. Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication. This research project aims to look at the mechanisms that exist to prevent this initial loss of genetic material within an individual cell. It further aims to translate theses discoveries into the clinic, providing new tools for diagnosis and prognosis of specific cancers and to establish links with major pharmaceutical companies to develop novel anticancer therapies.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.
Untangling the plant Golgi apparatus: Functional proteomics to understand plant cell wall biosynthesis. The plant cell wall determines plant morphology and structure. It is also a major factor in food quality, and it is used as forage and is the raw material for a range of industries. A significant proportion of the cell wall is synthesised in a poorly studied cellular compartment known as the Golgi apparatus. This project intends to exploit unique isolation and analytical techniques in conjunct ....Untangling the plant Golgi apparatus: Functional proteomics to understand plant cell wall biosynthesis. The plant cell wall determines plant morphology and structure. It is also a major factor in food quality, and it is used as forage and is the raw material for a range of industries. A significant proportion of the cell wall is synthesised in a poorly studied cellular compartment known as the Golgi apparatus. This project intends to exploit unique isolation and analytical techniques in conjunction to further profile and characterise this structure in order to uncover new information about the complex interplay of components involved in plant cell wall biosynthesis. This information will be used to support approaches to manipulate cell walls to produce plant biomass optimised for agricultural and industrial applications.Read moreRead less

Investigation of novel mechanisms for the regulation of sperm-oocyte interactions. Through work with national and international collaborators, this project aims to provide unprecedented insights into how spermatozoa recognise and bind to an oocyte. The approach is based on strong preliminary data indicating that molecular chaperones play a key role in the functional remodelling of the spermatozoon by promoting the assembly of multimeric oocyte receptor complexes.

Through work with national and international collaborators, this project aims to provide unprecedented insights into how spermatozoa recognise and bind to an oocyte. The approach is based on strong preliminary data indicating that molecular chaperones play a key role in the functional remodelling of the spermatozoon by promoting the assembly of multimeric oocyte receptor complexes. Through the use of state-of-the-art cell biology and proteomic technologies, the project aims to investigate how molecular chaperones orchestrate these changes and in doing so, improve understanding of the fertilisation cascade and open up new contraceptive strategies.Read moreRead less
How do mechanical cues regulate tissue renewal and tumour progression? Imbalances between cell production and cell death in tissues can be catastrophic, leading to major global health issues such as cancer. This project will use modified mice and protein-protein interaction based techniques to identify how changes in the mechanical properties of tissues regulate the balance between cell production and cell death.
