Understanding recidivism and repeat incarceration among young male offenders: a biographical and longitudinal approach. The research focuses on the group of offenders who, as a cohort, annually commit the most crime within Australia. The production of longitudinal qualitative data about individual experiences of secure care, release, and imprisonment, will provide a foundation for empirically driven policies and debates in the area of youth crime and incarceration for each state and territory. A ....Understanding recidivism and repeat incarceration among young male offenders: a biographical and longitudinal approach. The research focuses on the group of offenders who, as a cohort, annually commit the most crime within Australia. The production of longitudinal qualitative data about individual experiences of secure care, release, and imprisonment, will provide a foundation for empirically driven policies and debates in the area of youth crime and incarceration for each state and territory. Accordingly, the community will benefit through the generation of new possibilities for intervening in cycles of persistent offending and repeat custodial sentences. This has major social, cultural and economic implications. Read moreRead less
Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcripti ....Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcription on a genome-wide scale and will thereby reveal the full extent of mechanisms by which these important genetic switches control gene expression networks the characteristics of cells. This is of fundamental significance to our understanding of gene regulation.Read moreRead less
Suicide Terrorism: The Use of Life as a Weapon. Bali attacks were a powerful reminder that Australians are not immune from terrorism. Suicide terrorism is the most lethal form of terrorism. It constitutes 3 % of all terrorist attacks but accounts for 48 % of all deaths. Australia's involvement in Afghanistan, Iraq and East Timor has made Australia a more likely terrorist target. An informed understanding of suicide terrorism in our region would assist in developing appropriate policies for prote ....Suicide Terrorism: The Use of Life as a Weapon. Bali attacks were a powerful reminder that Australians are not immune from terrorism. Suicide terrorism is the most lethal form of terrorism. It constitutes 3 % of all terrorist attacks but accounts for 48 % of all deaths. Australia's involvement in Afghanistan, Iraq and East Timor has made Australia a more likely terrorist target. An informed understanding of suicide terrorism in our region would assist in developing appropriate policies for protecting Australia from terrorism. The research will also contribute to evaluation of costs and benefits of Australian government policies of democratisation in the region and War on Terror.Read moreRead less
Evolution and function of sex chromosomes and genes in mammalian reproduction. This project will ensure Australian leadership in research of reproductive biology and genomics in platypus and echidna. As our most distant relatives, these iconic species provide an understanding of human genes contributing to medical conditions involved in sexual development, infertility and ovarian cancer.
Transcription factor nuclear residency as a driver of gene expression. Persistently active proteins can stay in the nucleus to drive cell growth and prevent cell death. This project will define how one specific active protein can remain in the nucleus and regulate gene expression through the action of unique ribonucleic acid (RNA) molecules. The results will enable persistent gene activation to be manipulated in cancer.
Road rules for traffic on DNA - gene regulation by encounters between transcribing RNA polymerases and DNA-bound proteins. This project addresses a widespread but poorly understood phenomenon in gene regulation. The work will support Australian industries by supplying new tools for manipulation of gene expression for industrial and medical applications and will provide unique opportunities for Australian students in this emerging field.
Non-coding RNAs in mammalian reproduction. This project aims to investigate the role of non-coding RNAs in mammalian sex chromosome biology and reproduction. Non-protein coding RNAs are a major regulatory mechanism in eukaryotic genomes; they can bind other RNAs or chromatin modifying complexes. However, the evolutionary trajectory and function of non-coding RNAs in sex chromosome biology and sexual development is largely unknown. This project will study non-coding RNAs in Australian mammals to ....Non-coding RNAs in mammalian reproduction.

Non-protein coding RNAs are a major regulatory mechanism in eukaryotic genomes; they can bind other RNAs or chromatin modifying complexes. However, the evolutionary trajectory and function of non-coding RNAs in sex chromosome biology and sexual development is largely unknown. This project will study non-coding RNAs in Australian mammals to try to answer fundamental questions about how non-coding RNAs function in mammalian sexual development.Read moreRead less
Structural and molecular studies of endocrine disruption in Australia fauna. Contamination of waterways with compounds that disrupt hormone (endocrine) function is a major environmental problem and threat to the health and fertility of animals. Specifically, we lack an understanding of how these potent endocrine disrupting compounds function in native species. Using an innovative combination of structural and molecular biology approaches we will elucidate the mechanisms of action of environmenta ....Structural and molecular studies of endocrine disruption in Australia fauna. Contamination of waterways with compounds that disrupt hormone (endocrine) function is a major environmental problem and threat to the health and fertility of animals. Specifically, we lack an understanding of how these potent endocrine disrupting compounds function in native species. Using an innovative combination of structural and molecular biology approaches we will elucidate the mechanisms of action of environmental endocrine disrupting compounds in native aquatic species - model fish and the platypus; and develop novel technologies for their detection. This work will provide an understanding of the environmental threat of these pollutants to our unique wildlife and will guide future waterway management. Read moreRead less
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.
Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 fun ....Genetic control of spermatogenesis: defining the role of SOX3 in spermatogonial progenitor cells. The transcription factor (TF) SOX3 is a key regulator of neural stem/progenitor cells. Recently, this project has also shown that SOX3 is active in sperm progenitors (spermatogonia) and is required for spermatogenesis. Using our Sox3 KO mouse model and extensive expertise in spermatogonial cell culture, ChIP-seq technology and bioinformatics, this project will investigate crucial aspects of SOX3 function in the testes including stem versus progenitor cell activity and genome-wide target gene regulation. These studies will uncover the molecular and cellular mechanism by which SOX3 controls spermatogenesis and provide unique insight into how a single TF controls context-dependent differentiation in sperm versus brain progenitor cells.Read moreRead less
