Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
Development of a diagnostic microarray to detect aneuploidy in single cells. Chromosomal abnormalities account for about 10 per cent of all babies born with a defect. The risk of chromosomal abnormalities increases with maternal age and in patients with fertility problems. It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health ser ....Development of a diagnostic microarray to detect aneuploidy in single cells. Chromosomal abnormalities account for about 10 per cent of all babies born with a defect. The risk of chromosomal abnormalities increases with maternal age and in patients with fertility problems. It has been estimated that 50 per cent of all embryos are aneuploid. Chromosomal aberrations also occur in the vast majority of tumours in humans. Accurate and rapid detection of chromosomal defects is an important health service delivered to the Australian public. This project aims to develop better tests for application in prenatal diagnostics including non-invasive testing of fetal cells from maternal circulation or cervical samples at 6-13 weeks gestation, IVF and cancer diagnostics.Read moreRead less
HEN1 is a regulator of piRNA metabolism, transcriptional regulation and mammalian male fertility. This project is to define the biochemistry of a previously uncharacterized protein in male fertility using a unique mouse model and innovative DNA and protein technologies. This project will define a novel, and essential, pathway for male fertility and may ultimately have relevance to the maintenance of health or improving fertility.
Identifying the diversity and evolution of loci associated with adaptation to aridity/heat and salinity in ancient cereal crops. This project will use ancient grains of wheat, barley and rye to find 'lost' genetic diversity at key genes associated with resistance to aridity, salt and disease. This project will make the proteins of key genes, and study their interaction with the environment over time by measuring ions in the grains to reveal the ancient environmental conditions.

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
The birth and death of mammalian sex chromosomes. This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna.

This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna. This project will analyse the genetic and epigenetic composition and organisation of the monotreme autosomes that evolved into sex chromosomes in other mammals and compare individual platypus and echidna sex chromosomes to discover how sex chromosomes come to be, differentiate and ultimately are replaced by new sex chromosomes.Read moreRead less
