Funding Amount

Summary
Recent research has shown that a single injection of low-dose ketamine has powerful, though short-lived, antidepressant effects. Effective treatments are urgently needed for young people with severe depression. This will be the first controlled study to test whether repeated doses of ketamine, given over 4 weeks, is effective for young patients.
The Burden Of Late Preterm Birth On Brain Development And 2 Year Outcomes – A Prospective, Longitudinal Cohort Study

Summary
80% of preterm babies are born from 32-36 weeks’ gestation, and are late preterm (LPT). LPT children have more learning problems, but why this occurs is unknown. This study aims to understand the effect of LPT birth on brain development. We will do brain scans at term and assess development at 2 years of age of 200 LPT and 200 full-term children. We expect LPT babies will have subtle alterations in brain development compared with term controls which will be associated with delayed development.

Summary
Problems around birth are common and can have long-term implications, including into adulthood. Our goal is to improve health outcomes for all newborn babies and their families by determining factors that enhance outcome and assessing the benefits and consequences of new treatments for mothers and babies. We are world leaders in this field and are dedicated to training the next generation of health professionals in the care of newborn babies, in Australia and the rest of the world.
Intra-genomic conflict and the evolution of sexually selected traits. The dynamics of sexual selection may prevent the simultaneous optimization of traits shared by the sexes, or of different traits within each sex. This proposal focuses on the consequences of these conflicts for phenotypic and genomic evolution. First, I will compare selection acting on a sexually dimorphic trait in males and females. Second, I will use artificial selection to create a novel sexually dimorphic trait, and track ....Intra-genomic conflict and the evolution of sexually selected traits. The dynamics of sexual selection may prevent the simultaneous optimization of traits shared by the sexes, or of different traits within each sex. This proposal focuses on the consequences of these conflicts for phenotypic and genomic evolution. First, I will compare selection acting on a sexually dimorphic trait in males and females. Second, I will use artificial selection to create a novel sexually dimorphic trait, and track the evolutionary response. Third, I will investigate the link between two important fitness traits: body size and ageing rate. This work will enhance important on-going research in the laboratory of Robert Brooks (UNSW).Read moreRead less
A Dimensional Approach To Mapping The Risk Mechanisms Of Mental Illness

Summary
There is ongoing debate about whether current definitions of mental disorders are accurate. We will use statistical techniques to identify the core dimensions of liability for mental illness, and map how genes and brain organization drive differences between people along each dimension.
How sexually antagonistic genes and sexual selection influence the evolution of the Y chromosome. Sexually antagonistic genes are beneficial to members of one sex, but costly to the other. They are of significance both to the coevolution between the sexes and the evolution of the sex chromosomes. We will measure the sexually antagonistic effects of genes that make male guppies sexually attractive. We will then study how these genes, and the process of sexual selection that favours them influence ....How sexually antagonistic genes and sexual selection influence the evolution of the Y chromosome. Sexually antagonistic genes are beneficial to members of one sex, but costly to the other. They are of significance both to the coevolution between the sexes and the evolution of the sex chromosomes. We will measure the sexually antagonistic effects of genes that make male guppies sexually attractive. We will then study how these genes, and the process of sexual selection that favours them influence the process of recombination between the X and Y chromosomes.Read moreRead less
Putting sexual selection in a life-history context: What is meant by genetic quality? Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes ....Putting sexual selection in a life-history context: What is meant by genetic quality? Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes models of sexual selection is quality in the general ability to acquire resources, rather than in how resources are allocated among fitness components.Read moreRead less
Methods to infer dense genomic information from sparsely genotyped populations. Prediction of phenotype based on DNA polymorphisms or sequence has important applications such as prediction of disease risk in human medicine and prediction of genetic value in plant or animal breeding. This project will enhance precision and lower the cost of association studies leading to substantial increase in accuracy of such predictions. This will allow more effective genetic improvement, particularly of diff ....Methods to infer dense genomic information from sparsely genotyped populations. Prediction of phenotype based on DNA polymorphisms or sequence has important applications such as prediction of disease risk in human medicine and prediction of genetic value in plant or animal breeding. This project will enhance precision and lower the cost of association studies leading to substantial increase in accuracy of such predictions. This will allow more effective genetic improvement, particularly of difficult but important traits such as disease resistance, reduced green-house gas emissions and product quality. The same methods can be extended to improve genetic improvement in plants and better prediction of human disease risk. Read moreRead less
