Deciphering the genetic architecture of human complex traits. This project aims to develop statistical methods to integrate data from genetic studies of complex traits such as stature and cognition. Molecular phenotypes such as gene expression in large samples will be used to predict target genes and regulatory elements of those traits. Understanding the genetic basis of human complex traits is critical to longstanding questions in human and evolutionary biology.

This project aims to develop statistical methods to integrate data from genetic studies of complex traits such as stature and cognition. Molecular phenotypes such as gene expression in large samples will be used to predict target genes and regulatory elements of those traits. Understanding the genetic basis of human complex traits is critical to longstanding questions in human and evolutionary biology. The project will also detect signatures of natural selection in shaping the genetic variation in complex traits. The project will provide better understanding of complex traits in global populations and the history of human evolution, and will develop methods applicable in plant and animal contexts.Read moreRead less

Phenotypic profiling from DNA using genetic and epigenetic information. The project intends to quantify how much information about a person can be inferred from a DNA sample. A DNA sample contains epigenomic information additional to the genome sequence. This information can reflect age and the past and present lifestyle of the individual whose sample it is. The project aims to quantify the accuracy of lifestyle and phenotypic prediction from DNA. Existing genome-wide genotype and methylation ar ....Phenotypic profiling from DNA using genetic and epigenetic information. The project intends to quantify how much information about a person can be inferred from a DNA sample. A DNA sample contains epigenomic information additional to the genome sequence. This information can reflect age and the past and present lifestyle of the individual whose sample it is. The project aims to quantify the accuracy of lifestyle and phenotypic prediction from DNA. Existing genome-wide genotype and methylation array data from thousands of blood samples from human subjects will be statistically analysed to develop and validate predictors for chronological age, smoking, caffeine use, pesticide exposure, diet and body mass index. Potential applications of epigenomic prediction are widespread, ranging from forensics to ecology.Read moreRead less
The role of X-chromosome inactivation in quantitative trait variation. This project aims to develop methods and software that can be applied to genetic and genomic studies in animal breeding, wildlife protection, and humans. X-chromosome inactivation (XCI) is an important biological phenomenon but its effect on quantitative trait variation remains largely unknown. This project aims to develop novel statistical methods to estimate the X-linked genetic variance and the proportion that escapes XCI, ....The role of X-chromosome inactivation in quantitative trait variation. This project aims to develop methods and software that can be applied to genetic and genomic studies in animal breeding, wildlife protection, and humans. X-chromosome inactivation (XCI) is an important biological phenomenon but its effect on quantitative trait variation remains largely unknown. This project aims to develop novel statistical methods to estimate the X-linked genetic variance and the proportion that escapes XCI, and identify trait-associated genetic variants affected and not affected by XCI. The methods would then be applied to large datasets from genome-wide association studies for a large number of traits. Project outcomes may enable us to better understand the role of XCI in quantitative trait variation and gene expression in humans and animals.Read moreRead less
Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet ....Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet poorly understood issue in mitochondrial genomics and evolutionary biology. Knowledge from this project will also improve our understanding of other important issues that are associated with animal mitochondria; like the mechanisms of mitochondrial disease and ageing, and the evolution of modern humans and other animals.Read moreRead less
Fertility crisis: harnessing the genomic tension behind pollen fertility in sorghum. Hybrid sorghum varieties yield more grain than inbred varieties but the production seed for farmers can be difficult. This project will identify the genes responsible for a trait that makes hybrid seed production possible and this knowledge will help raise sorghum yields in Australian and in some of the world’s poorest countries.

Summary
Characterisation of nuclear-localised microRNAs. This project is focused on a set of very small RNA molecules, called microRNAs that regulate genes activity. This project will likely redefine our understanding of microRNA-based gene regulation in complex animals, and may result in new RNA therapeutics for previously untreatable illnesses.

Identifying parent-of-origin effects and their impact on complex traits. This project aims to systematically identify genetic variants whose effects depend on whether they were inherited from the mother or the father, and to assess their impact on complex human traits. Most gene mapping studies to date assume that the effects of genetic variants are equal regardless of the parent of origin, thus have not explored this source of genetic variation. However, animal studies indicate that parent-of-o ....Identifying parent-of-origin effects and their impact on complex traits. This project aims to systematically identify genetic variants whose effects depend on whether they were inherited from the mother or the father, and to assess their impact on complex human traits. Most gene mapping studies to date assume that the effects of genetic variants are equal regardless of the parent of origin, thus have not explored this source of genetic variation. However, animal studies indicate that parent-of-origin specific effects (POEs) are important contributors to variability of developmental and behavioural traits. Leveraging genetic and epigenetic data from some of the world’s largest cohorts, this project will improve our understanding of POEs on complex human traits related to early development, growth and behaviour.Read moreRead less
Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric i ....Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric instability and the insertion of transposable elements, a dynamic balance between structural conservation and rapid evolution. This is a rare opportunity to understand the forces at work in moulding eukaryotic sub-telomeric sequences because Giardia is not constrained by sexual homogenisation and the dynamic variability is retained.Read moreRead less
