The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
Understanding the link between reading impairments and emotional problems. This Project aims to understand why children with reading impairments are at increased risk for emotional problems. By integrating the statistical power of large-scale longitudinal studies with the causal testing power of intervention case studies, it seeks to fast-track the development of a comprehensive evidence-based theory of the mechanisms linking reading impairments and emotional problems.

This Project aims to understand why children with reading impairments are at increased risk for emotional problems. By integrating the statistical power of large-scale longitudinal studies with the causal testing power of intervention case studies, it seeks to fast-track the development of a comprehensive evidence-based theory of the mechanisms linking reading impairments and emotional problems. The outcomes will pave the way for future diagnosis and treatment of concomitant reading and emotional difficulties in children. These outcomes improve our capacity to reduce the incidence of two common problems that limit the life success of Australian children - poor literacy and poor emotional health.Read moreRead less

This project will inform the community about factors that affect the psychological, physical, academic, and employment outcomes of emerging adults. It will improve our knowledge of why some young people do not reach their full potential. The project will provide a comprehensive assessment of factors associated with well-being across several domains. It will better equip and assist professionals to identify early those youth at risk of having poor psychological, health, and employment prospects post-school. The project will inform the development of intervention programs for young people and maximise their overall adjustment and well-being several years later.Read moreRead less
Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more princi ....Towards an integrated model of reasoning and reasoning development. This project aims to identify the core cognitive processes that underlie different forms of reasoning and how they develop. The project intends to use a signal detection framework to derive detailed computational models of reasoning which can then be tested through Bayesian computational modelling as well as the first systematic investigation of developmental change in reasoning processes. Expected outcomes include a more principled and comprehensive computational model of reasoning in both adults and children. The project should provide significant benefits by helping to resolve long-standing debates about how humans reason complex arguments relevant to everyday lives and guide development of more effective methods for teaching reasoning.Read moreRead less
Intergenerational Prediction of Social and Early Emotional Development. This project aims to investigate multi-generational influences on child psychosocial development. It plans to take advantage of a not-to-be-repeated opportunity to follow offspring born to one of Australia’s oldest longitudinal studies of social and emotional development. The Australian Temperament Project has followed around 2000 parents and offspring across 30 years from birth in 1983. Third-generation babies have been fol ....Intergenerational Prediction of Social and Early Emotional Development. This project aims to investigate multi-generational influences on child psychosocial development. It plans to take advantage of a not-to-be-repeated opportunity to follow offspring born to one of Australia’s oldest longitudinal studies of social and emotional development. The Australian Temperament Project has followed around 2000 parents and offspring across 30 years from birth in 1983. Third-generation babies have been followed across the peak period of first births to females. This project plans to continue recruitment across the peak period of first births for males in 2016–18. This would create one of the most extensive and well-powered three-generation resources worldwide, yielding unique data on intergenerational pathways through mother and father lines. It expects to inform targeting of interventions and psychosocial resources to promote wellbeing within and across generations.Read moreRead less
Preconception predictors of early childhood social and emotional development: a 30-year longitudinal study of grandparents, parents and children. There is increasing recognition of the importance of preconception pathways in shaping the family environments that parents provide for their children. This project will advance understandings of preconception pathways to healthy early child development, by recruiting offspring born to a 30-year longitudinal study: The Australian Temperament Study.
Comprehensive characterisation of DNA demethylation pathways in vivo. This project aims to provide a better understanding of the roles that DNA methylation plays during embryonic development. DNA methylation is a major regulatory mark present in vertebrate genomes. It is well established that the genomic patterns of DNA methylation are being actively remodelled during vertebrate embryogenesis. Nevertheless, it remains unclear how these events impact gene regulation and embryonic development itse ....Comprehensive characterisation of DNA demethylation pathways in vivo. This project aims to provide a better understanding of the roles that DNA methylation plays during embryonic development. DNA methylation is a major regulatory mark present in vertebrate genomes. It is well established that the genomic patterns of DNA methylation are being actively remodelled during vertebrate embryogenesis. Nevertheless, it remains unclear how these events impact gene regulation and embryonic development itself. This project expects to unravel the functional contributions of DNA methylation to vertebrate embryogenesis by using latest cutting-edge genomics techniques. The project will be carried out on the highly tractable zebrafish model system which allows for easy genetic manipulation of the desired sequences. This project aims to provide a better understanding of embryonic development of vertebrates, including humans.Read moreRead less
Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family protei ....Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family proteins as specific effectors. This project will address a new paradigm in genetics that is likely to underpin development.Read moreRead less
Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how tem ....Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how temperature reverses chromosomal sex determination in dragon lizards. This could show how climatic extremes affect the biology of climate sensitive reptiles, and understand their vulnerability to climate change.Read moreRead less
