The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Survival mechanisms of teeth. The patterns of fracture in teeth can be used to infer bite forces and dietary habits in human ancestors and other animals, yet the link between the fracture pattern and forces is not yet well understood. This project will enable new developments in the field of evolutionary biology by providing mathematical models that can predict these forces.
Continuous tooth replacement in mammals: revealing the fundamental processes in tooth generation and movement. This project will investigate how molar teeth are made in mammals by examining the nabarlek, or little rock-wallaby, which is one of a handful of mammals that is able to regenerate new molars throughout its life. These new teeth migrate through the bone in order to move into the correct position in the mouth. By investigating two well-studied organisms, the mouse and the tammar wallaby, ....Continuous tooth replacement in mammals: revealing the fundamental processes in tooth generation and movement. This project will investigate how molar teeth are made in mammals by examining the nabarlek, or little rock-wallaby, which is one of a handful of mammals that is able to regenerate new molars throughout its life. These new teeth migrate through the bone in order to move into the correct position in the mouth. By investigating two well-studied organisms, the mouse and the tammar wallaby, as well as the nabarlek itself, the developmental processes and genes involved in molar generation and movement will be revealed. This project will integrate findings in regenerative medicine, evolutionary biology, materials engineering and palaeontology to reveal the mechanisms and origins of this astounding capability.Read moreRead less
Australian Heritage: constructing the first Aboriginal reference genome. This project aims to use DNA sequencing technologies to generate the first complete and accurate Aboriginal genomes, along with maps of genomic variation around Australia. It will combine a range of advanced analytical methods to integrate past and present indigenous genetic diversity from human populations around the world into a new pan-human reference genome. This project will lead to a step change in our understanding o ....Australian Heritage: constructing the first Aboriginal reference genome. This project aims to use DNA sequencing technologies to generate the first complete and accurate Aboriginal genomes, along with maps of genomic variation around Australia. It will combine a range of advanced analytical methods to integrate past and present indigenous genetic diversity from human populations around the world into a new pan-human reference genome. This project will lead to a step change in our understanding of global human genomic variants and provide a range of new targets relevant to medical biology, while significantly improving our knowledge of human genetic history and its consequences in the modern day.Read moreRead less
The genomic landscape of speciation in hominins and other taxa. This project will develop a new analytical framework to build detailed genomic maps of speciation genes across different taxa, to determine whether observed speciation is the result of background selection and demography alone, or whether there are actual barriers to gene flow and introgressed DNA. The model will provide novel insights into the mechanistic basis of speciation, specifically whether a common set of genes or pathways a ....The genomic landscape of speciation in hominins and other taxa. This project will develop a new analytical framework to build detailed genomic maps of speciation genes across different taxa, to determine whether observed speciation is the result of background selection and demography alone, or whether there are actual barriers to gene flow and introgressed DNA. The model will provide novel insights into the mechanistic basis of speciation, specifically whether a common set of genes or pathways are central to the speciation process. The framework will be developed using the large genomic datasets available across a range of plant and animal species. Applying the model to a modern human population dataset will elucidate the role introgressed DNA from Denisovan and Neanderthals has played in shaping human evolutionary history and may provide novel insights into the genetic basis of disease.Read moreRead less
Screening platforms for malaria drug discovery: identification of new therapeutics. Innovative image based technologies will be developed to identify molecules which stop malaria parasite growth and its transmission to the mosquito host. As more resistance is emerging against the current drugs of choice, new molecules acting through different mechanisms are urgently needed.
Challenging current dogma on the inheritance of mitochondrial DNA. Mutations in mitochondrial DNA are often used to infer genetic relationships and have been associated with the expression of human diseases. This project examines the exact mechanism of inheritance of mitochondrial genes to enhance biological interpretations and our understanding of the heritability of specific diseases.

Functional insights into the roles of enteric glia. This project aims to review our current definition of enteric glia populations, and our understanding of their communication mechanisms in the mouse and primate colon. It will generate new knowledge of enteric glia biology using advanced microscopy and image analysis. Calcium imaging and novel biosensors will measure cell signalling in enteric glia. It will provide the most comprehensive analysis of glia connectivity, morphology and receptor ex ....Functional insights into the roles of enteric glia.

It will generate new knowledge of enteric glia biology using advanced microscopy and image analysis. Calcium imaging and novel biosensors will measure cell signalling in enteric glia. It will provide the most comprehensive analysis of glia connectivity, morphology and receptor expression in the primate colon. Expected outcomes include a detailed map of enteric glia and definitions of their basic biology. This project builds on the techniques and collaborations made by the candidate over recent years. This will benefit our basic understanding of enteric glia biology.Read moreRead less

Developing custom RNA processing tools. The pentatricopeptide repeat (PPR) code has been described as an RNA code that connects specific residues in PPR motifs with the precise recognition of individual nucleotides. It will enable the design of custom RNA-binding proteins with tremendous potential in research and biotechnology. RNA-processing technologies aim to be developed that consist of PPR domains fused with an additional endonuclease domain for cleaving chosen target RNAs.

Unlocking malaria invasion by ultraresolution microscopy. This project describes the microscopic analysis of malaria-causing parasites invading human blood cells. The project aims to better understand how this invasion works and to understand how it might be inhibited.
Attentional and conditioning mechanisms that mediate overcoming anxiety. Anxiety is a common emotion for most Australians that can cause substantial costs for individuals and society. This project uses dominant psychological models to identify critical mechanisms that are believed to predict capacity for, and change in, anxiety. Outcomes substantially advance knowledge about how humans overcome anxiety.
