Summary
One in 20 children have a speech disorder at school entry, with lifelong deficits in psychosocial, academic and employment outcomes. Little is known about the aetiology of speech disorders, preventing targeted care. We combine expertise in speech pathology, gene discovery and brain imaging, to advance knowledge on gene and brain contributions to speech disorder. We will have direct impacts on clinical care including detection, diagnosis and counselling, optimising outcomes for affected children.
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
Left-right patterning of the heart. This project aims to investigate how the heart responds to left-right (LR) signals, which tissue is dominant in this response; determine tissue intrinsic factors at play, and determine whether we can manipulate this. Expected outcomes include fundamental information about how organs are patterned.
cell-cell adhesive force in vascular development. This project aims to utilize groundbreaking new approaches to visualize cell-cell adhesive forces in vascular development. Vascular system development is one of the earliest events in the vertebrate embryo. It has long been established that one major contributor to the formation of new vessels is physical force, which can be generated through blood flow or cell-cell interactions during tissue morphogenesis. The project plan utilizes live imaging ....cell-cell adhesive force in vascular development. This project aims to utilize groundbreaking new approaches to visualize cell-cell adhesive forces in vascular development. Vascular system development is one of the earliest events in the vertebrate embryo. It has long been established that one major contributor to the formation of new vessels is physical force, which can be generated through blood flow or cell-cell interactions during tissue morphogenesis. The project plan utilizes live imaging in zebrafish and a new generation of biosensors to gain a vastly deeper understanding of how force controls vessel formation.Read moreRead less

This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore h ....Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore how this pattern is established, how it dictates kidney development and whether it constitutes an ancient mechanism central to organ formation. Project outcomes may improve understanding of fundamental developmental processes and developmental disease and variation. Project findings may also be important for understanding the development of other organ systems.Read moreRead less
Redefining the molecular mechanism underlying crustacean metamorphosis. This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production. The project suggests that the current accepted paradigm for the molecular control of metamorphosis does not apply to lobsters ....Redefining the molecular mechanism underlying crustacean metamorphosis. This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production. The project suggests that the current accepted paradigm for the molecular control of metamorphosis does not apply to lobsters and possibly other crustaceans where larval metamorphosis and the juvenile transformation are uncoupled. Using a unique supply of cultured lobsters and advanced molecular techniques, the project aims to develop tools to trigger and synchronise metamorphosis for use in aquaculture and invasive species management.Read moreRead less
Defining the earliest events in lymphatic vasculature formation from veins. Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo. The project aims to utilise zebrafish and mouse embryos to greatly expand knowledge in the forma ....Defining the earliest events in lymphatic vasculature formation from veins. Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo. The project aims to utilise zebrafish and mouse embryos to greatly expand knowledge in the formation of this essential vertebrate tissue. Ultimately, this is expected to provide new knowledge in stem and precursor cell differentiation, the evolution of complex organ systems and tissue formation. Outcomes may impact on future biotechnology in the areas of tissues engineering, stem cell differentiation and regeneration.Read moreRead less
Genetic analysis of lymphatic vascular development. This project investigates the fundamental molecular components that regulate lymphatic vascular system development in the zebrafish embryo. Lymphatic vessels play critical roles in vascular diseases and cancer metastasis. This study will identify and examine key new molecules that will further our basic understanding of lymphatic development.
The molecular control of lymphatic vascular differentiation. This project aims to improve our understanding of how a new vascular system forms and the molecules that control this process. Lymphatic vasculature plays roles in fluid drainage, inflammation, obesity, metastasis and tissue repair, yet we cannot readily promote or inhibit lymphatic vessel formation. This project aims to build new knowledge that is expected to improve our ability to generate lymphatic vessels for stem cell application ....The molecular control of lymphatic vascular differentiation.

Regulation of organ size and stem cell hierarchy in the developing kidney. Transient stem/progenitor cell populations play essential roles in establishing organ systems. The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity.

The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity. What is not clear is how the balance between self-renewal and differentiation is regulated in these cells, nor how the control of this fate decision impacts on optimal organ development. This project aims to dissect the molecular identity, regulation, and influence of this stem cell population on kidney development.Read moreRead less
