Hidden complexity in microRNA function. This project aims to determine the extent to which microRNAs function through “non-canonical” mechanisms within cell nuclei, how their roles are expanded by naturally occurring sequence variation and how their activity is controlled by little known families of genes that sequester and inhibit their availability. The knowledge generated is significant as microRNAs regulate the expression of virtually all genes and biological processes, yet these mechanisms ....Hidden complexity in microRNA function. This project aims to determine the extent to which microRNAs function through “non-canonical” mechanisms within cell nuclei, how their roles are expanded by naturally occurring sequence variation and how their activity is controlled by little known families of genes that sequester and inhibit their availability. The knowledge generated is significant as microRNAs regulate the expression of virtually all genes and biological processes, yet these mechanisms of function remain poorly characterised and seldom considered. The expected outcome of better understanding mechanisms through which microRNAs work should provide significant benefit to safe and effective development of microRNAs for future agricultural or therapeutic application.Read moreRead less

The non-coding genome is recognized as a major player in orchestrating gene expression in higher eukaryotes. This project aims to identify regions of the human genome that are important for gene expression during neuronal differentiation and depolarisation (i.e. neural enhancers), and to investigate their evolutionary properties. The roles of non-coding DNA in regulating the dynamic gene expression patterns underlying complex human brain functions remains to be elucidated. By combining transcriptome quantification and bioinformatics methods, this project will close an important knowledge gap in our understanding of transcriptional regulation underlying human brain function. This will provide benefits such as the potential to influence public health policy including in cognitive functions and aging.Read moreRead less
The transcriptome dynamics that refine eukaryotic gene expression. This project aims to understand the fundamental mechanisms of gene expression control, by exploring how cells respond to acute perturbation with changes to RNA expression and processing.

What about the children? A study of the intergenerational consequences of paternal incarceration. Parental incarceration may have a profound and detrimental effect on children, heightening risk of offending and extreme disadvantage. The proportion of children affected is certain to increase as prison populations continue to grow.

A study of the intergenerational consequences of paternal incarceration. Parental incarceration may have a profound and detrimental effect on children, heightening risk of offending and extreme disadvantage. The proportion of children affected is certain to increase as prison populations continue to grow. This research will identify policies and prevention strategies that will interrupt the cycle of disadvantage for children of prisoners and prevent social exclusion. Significant cost-savings and prevention of victimisation could result from effectively targeting this high-risk population, reducing risk of offending and increasing the young person's ability to contribute meaningfully to society. Appropriately timed programs can deliver a range of long-term benefits for children, families and communities.Read moreRead less
