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.

Summary
Regulation of organ size and stem cell hierarchy in the developing kidney. Transient stem/progenitor cell populations play essential roles in establishing organ systems. The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity. What is not clear is h ....Regulation of organ size and stem cell hierarchy in the developing kidney. Transient stem/progenitor cell populations play essential roles in establishing organ systems. The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity. What is not clear is how the balance between self-renewal and differentiation is regulated in these cells, nor how the control of this fate decision impacts on optimal organ development. This project aims to dissect the molecular identity, regulation, and influence of this stem cell population on kidney development.Read moreRead less
Investigating spermatogonial stem cell allocation in the fetal testis. This project aims to determine when and how spermatogonial stem cells (SSCs) are specified, and whether a genetic pathway that is used by in vitro stem cells is also employed, in vivo, by testicular stem cells. The project aims to deliver insight into the mechanisms of adult stem cell specification and regulation, in general. Intended practical outcomes of this work will underpin new methods for fertility management in animal ....Investigating spermatogonial stem cell allocation in the fetal testis. This project aims to determine when and how spermatogonial stem cells (SSCs) are specified, and whether a genetic pathway that is used by in vitro stem cells is also employed, in vivo, by testicular stem cells. The project aims to deliver insight into the mechanisms of adult stem cell specification and regulation, in general. Intended practical outcomes of this work will underpin new methods for fertility management in animals (in agriculture and conservation of endangered species) and humans. Knowledge gained will inform our understanding of stem cell biology more broadly and guide efforts to treat infertility or control fertility in animals and humans.Read moreRead less
Tracking factor footprints to reveal the intricacy and control of translation initiation. Messenger ribonucleic acid (RNA) translation is required for all of life and knowledge of how it works is central to modern life sciences. This project will develop novel ways of studying translation, generating entirely new descriptions of its inner workings that may transform knowledge of gene function and its use in medical and biotechnological processes.

Summary
The immune system is poised to respond to invading viruses or bacteria and eliminate them as efficiently as possible. Incorrect activation of the immune system leads to chronic inflammation and autoimmunity. Immune cells can also grow in an uncotrolled manner causing leukamia. The cells of the immune system recognise pathogens and respond by altering the patterns of proteins produced by the cells allowing the system to eliminate the invading organisms. The altered protein production patterns ste ....The immune system is poised to respond to invading viruses or bacteria and eliminate them as efficiently as possible. Incorrect activation of the immune system leads to chronic inflammation and autoimmunity. Immune cells can also grow in an uncotrolled manner causing leukamia. The cells of the immune system recognise pathogens and respond by altering the patterns of proteins produced by the cells allowing the system to eliminate the invading organisms. The altered protein production patterns stem from changes in the gene expression profile of the cells. The gene expression profile of the cell is determinded by the activity of proteins called transcription factors. One such factor, c-Rel, has been implicated in allergy, autoimmunity, in transplant rejection and in leukemia. The aim of this project is to study the function of c-Rel in T cells, an important cell type in the immune system. The overall aim is to understand how c-Rel controls the gene expression profile of T cells so that a rational basis for c-Rel as a drug target can be designed.Read moreRead less
Unravelling the contributions of Denisovan DNA to the peoples of Oceania. This project aims to investigate the impact gene flow from Denisovans, an archaic hominin species, has had on individuals from Papua New Guinea and eastern Indonesia. These people owe up to 5% of their genomes to these mysterious ancestors, but the repercussions of this finding remain poorly understood. In order to identify the biological contributions these fragments of DNA make to the individuals who carry them, this pro ....Unravelling the contributions of Denisovan DNA to the peoples of Oceania. This project aims to investigate the impact gene flow from Denisovans, an archaic hominin species, has had on individuals from Papua New Guinea and eastern Indonesia. These people owe up to 5% of their genomes to these mysterious ancestors, but the repercussions of this finding remain poorly understood. In order to identify the biological contributions these fragments of DNA make to the individuals who carry them, this project aims to combine anthropological genetics with cutting-edge functional genomics in a pioneer multidisciplinary approach. Ultimately, this project may transform our understanding of both the population and evolutionary pressures that have acted upon these groups in the past 50,000 years.Read moreRead less

Summary
Identification and characterisation of anti-viral immune response genes in mosquitoes. Emerging viral diseases, transmitted by mosquito bite, present an increasing public health risk globally. Most research to date has neglected the infection dynamic in the insect vector. This project aims to characterise the defensive response of mosquitoes to viral infection, a potentially crucial factor in the epidemiology of vector-borne disease.

Summary
How does viviparity evolve? Genetic perspectives from a unique model system. By integrating decades of Australian natural history research with the same technology that allowed researchers to sequence the genome of the woolly mammoth, this project seeks to uncover the genetic mechanisms responsible for the transition from egg-laying to live-bearing in reptiles.
The evolutionary origin, cellular response and genetic impact of insecticide resistance mutations in agricultural pests. Diamondback moth is a global pest of canola and Brassica vegetables, and populations can rapidly evolve resistance to insecticides. The project will use a combination of genome sequencing, fieldwork and gene expression analysis to identify mutations causing resistance to Bt insecticidal toxins and assess the threat of resistance evolving in Australia.

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.
