Summary
I am a cellular and molecular biologist with extensive training in a number of biomedical research areas. For over 20 years I have used my training and skills to understand the normal functioning of the body and what molecular and cellular changes underlie various diseases. This fellowship will allow me to continue the groundbreaking work we have been doing to explore the function of several proteins in diseases such as cancer, hypertension, lung inflammation and anaemia.

Summary
The AID enzyme is implicated in cancer in B lymphocytes and prostate cells. AID causes DNA damage normally recognised by repair enzymes UNG and MutS?, among others. The repair processes these factors initiate involve a DNA break that, if incorrectly re-joined, destabilises the genome, causing cancer. Understanding the function of AID, UNG and MutS? in B cell lymphomas and prostate cancer will provide fundamental insights into cancer and may identify targets for new therapeutics.

Understanding the role of miRNAs in the biology of ageing muscle. Skeletal muscle is the largest organ in the body and plays a vital role in maintaining independent living and social interaction. As it ages, skeletal muscle loses its ability to build up new muscle proteins. However, the principles underlying the biology of skeletal muscle ageing are not well understood. MicroRNAs (MiRNAs) are essential regulators of skeletal muscle biology. Whether they play a role in the ageing process and how ....Understanding the role of miRNAs in the biology of ageing muscle. Skeletal muscle is the largest organ in the body and plays a vital role in maintaining independent living and social interaction. As it ages, skeletal muscle loses its ability to build up new muscle proteins. However, the principles underlying the biology of skeletal muscle ageing are not well understood. MicroRNAs (MiRNAs) are essential regulators of skeletal muscle biology. Whether they play a role in the ageing process and how they regulate muscle protein synthesis as we age has not been investigated. This project aims to identify the MiRNA species involved in muscle protein synthesis and will provide a better understanding of the biology of ageing skeletal muscle.Read moreRead less

Determining the regulation of ovary development with single cell sequencing. This project will greatly advance our understanding of ovary development and mammalian reproduction. I will investigate the process of ovarian primordial follicle activation including its genetic regulation, the importance of supportive granulosa cells and the biological significance of regulatory factors. This will be achieved through the comprehensive investigation of a single cell transcriptomic dataset of ovarian de ....Determining the regulation of ovary development with single cell sequencing. This project will greatly advance our understanding of ovary development and mammalian reproduction. I will investigate the process of ovarian primordial follicle activation including its genetic regulation, the importance of supportive granulosa cells and the biological significance of regulatory factors. This will be achieved through the comprehensive investigation of a single cell transcriptomic dataset of ovarian development (Aim 1) in conjunction with functional studies (Aim 2). The outcomes of which will hold significant benefit to animal reproduction through new strategies to improve livestock productivity and control invasive pest species. These outcomes are of economic and environmental and benefit nationally.Read moreRead less
Purinergic signalling in placentation and vascular adaptation in pregnancy. Our traditional understanding of purinergic signalling in the placenta is significantly outdated and incomplete. The placenta is critical for reproduction in all eutherian mammals, delivering critical nutrition and oxygen to the developing fetus. This project aims to define the role of purinergic signalling as a critical mechanism driving placentation and angiogenesis. This is the first study of its kind and will use sop ....Purinergic signalling in placentation and vascular adaptation in pregnancy. Our traditional understanding of purinergic signalling in the placenta is significantly outdated and incomplete. The placenta is critical for reproduction in all eutherian mammals, delivering critical nutrition and oxygen to the developing fetus. This project aims to define the role of purinergic signalling as a critical mechanism driving placentation and angiogenesis. This is the first study of its kind and will use sophisticated models to improve our fundamental understanding and ability to manipulate mammalian reproduction via the purinoreceptors. This proposal builds on my skills and expertise; improving our knowledge of the processes driving placental and vascular morphogenesis and offers important discoveries for reproductive science.Read moreRead less
Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blo ....Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blood flow and the exchange of expertise between leading researchers in Australia and Canada. In the long-term, this will enhance Australia’s research capacity in fetal physiology and may lead to new tools for monitoring or supporting fetal development.Read moreRead less
Opening and closing doors in the fetal circulation impacts brain metabolism. This project aims to measure blood flow from the umbilical cord through special shunts or doors to the fetal brain and to understand how changes in delivery of oxygen may impact fetal brain metabolism.

Gamete-specific knockout of Fizzy-Related to examine its meiotic role in oocytes and sperm. Fizzy-Related is a gene that appears to be essential in making an ovulated egg, and it may also have an important role to play in making sperm. A mouse knockout will be generated to examine exactly how it functions; because it affects the egg number remaining in the ovary and egg quality Fizzy-Related may be eventually an important therapeutic target.

Summary
Regulation of germ cell number and quality by Fizzy-related protein. Females have a limited supply of eggs in their ovaries and it appears that the Fizzy-related gene (FZR1) is important in making sure this full complement is gained. By using novel mouse knockouts of the FZR1 gene, the project will determine how this protein functions at the earliest stages of egg development.
