Brain sodium channel: functional role of developmentally regulated alternative splicing. This project will identify the roles of neonatal and adult forms of a sodium channel in the function of neurons in the developing brain. Sodium channels are vital for brain function and this study will improve our understanding of the function of healthy brain as well as of underlying mechanisms of some neurological disorders.

Communicating genetic information in families: practical, legal, social and ethical issues. The outcomes of this study, will give evidence as to whether or not people do pass on genetic risk information to relatives, how they do it, what the barriers are, what their preferences are. It will also provide data so that mechanisms for best practice communication and clear guidelines for legal and health professionals can be developed. Effective communication and exchange of genetic risk information ....Communicating genetic information in families: practical, legal, social and ethical issues.

It will also provide data so that mechanisms for best practice communication and clear guidelines for legal and health professionals can be developed. Effective communication and exchange of genetic risk information will benefit individual health and the health of future generations.Read moreRead less
Shaping the heart in early development - new insights into cellular modelling processes. Heart health is an important contributor to quality of life and longevity. This research will provide new insights into the way hormonal influences early in development shape a healthy heart. The project builds on the application of recently patented, sophisticated cell imaging techniques. Research students and trainees recruited to this project will benefit from their involvement with this leading edge tech ....Shaping the heart in early development - new insights into cellular modelling processes. Heart health is an important contributor to quality of life and longevity. This research will provide new insights into the way hormonal influences early in development shape a healthy heart. The project builds on the application of recently patented, sophisticated cell imaging techniques. Research students and trainees recruited to this project will benefit from their involvement with this leading edge technology. These studies are important in providing a basis for developing optimal management strategies for congenital heart conditions and preterm infants. Improved knowledge of the cardiac effects of fetal and neonatal exposure to steroids (to assist with lung maturation in prematurity or to control maternal asthma) will be gained.Read moreRead less
Understanding and exploiting bacterial sulfatases. Bacterial sulfatases participate in environmental nutrient cycling and are implicated in bacterial pathogenesis mechanisms. These enzymes catalyze the hydrolysis of sulfate esters and possess an unusual posttranslational active-site modification where a cysteine residue is oxidized to formylglycine. We will study the mechanism of these enzymes in detail and design inhibitors that exploit the reactivity of this aminoacid. This work has significan ....Understanding and exploiting bacterial sulfatases. Bacterial sulfatases participate in environmental nutrient cycling and are implicated in bacterial pathogenesis mechanisms. These enzymes catalyze the hydrolysis of sulfate esters and possess an unusual posttranslational active-site modification where a cysteine residue is oxidized to formylglycine. We will study the mechanism of these enzymes in detail and design inhibitors that exploit the reactivity of this aminoacid. This work has significance because of application to areas that include the treatment of cancer and bacterial infections. Additionally, we will clone novel carbohydrate sulfatases from the heparin-degrading bacterium Flavobacterium heparinum. These sulfatases will have use in biotechnology for characterization of sulfated glycoconjugates.Read moreRead less
Elucidating the neural pathways and genetic basis of speech. The project will elucidate the biological basis of speech, a unique feature of the human condition. The project will do this by i) discovering genes associated with speech disorder and ii) defining the neural pathways associated with speech production. This study will address critical questions regarding gene, brain and behaviour relationships in speech.
Stuttering in childhood: Patterns of recovery and persistence. This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scienti ....Stuttering in childhood: Patterns of recovery and persistence. This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scientific community and provide professionals and families with much needed evidence-based information about stuttering progression. Together this information will inform intervention approaches and help direct resources to those children who need them most. Read moreRead less
How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understandi ....How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less
