“Killer T cells” are specialised cells that help control viral infection. T cells recognize virus via proteins called “T cell receptors” (TCR). TCR are incredibly diverse, allowing us to recognise many different viruses. Recent advances in technology allow us to look at TCR and the genes encoding them, however their complexity makes that data difficult to interpret. I will use mathematical and statistical approaches to analyse and model this data to better understand immune recognition.
The Importance Of Superstars: Cell Numbers And Lineages In Enteric Nervous System Formation

Summary
All digestive functions are controlled by a nerve system in the gut wall, and it works without us thinking about it. This is a huge system rivalling the spinal cord in number of nerve cells. And it has may different types of nerve cells. It originates from a very few cells early in the embryo, about 200 times fewer than the spinal cord. How do the cells manage to divide enough to make this system, and how do they 'know' how to make the right types of nerve cells in the right places in the gut?
Investigating Post-transcriptional Gene Regulation In Cancer

Summary
In this program, I will enhance our understanding of cancer gene regulation and provide novel avenues for the treatment of aggressive tumours. Using own data and that from collaborators, I will determine patterns of gene regulation in blood cancers and identify markers that predict disease outcome. I aim to understand how gene regulation can transform healthy cells into tumour cells and whether personalised treatment can kill tumour cells more effectively and prevent relapse and metastasis.
Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old musc ....Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old muscles young again, is a research strategy that will promote healthy ageing and enable older Australians to enjoy a better quality of life.Read moreRead less
Central Muscarinic Receptors as Novel Drug Targets for Parkinson's Disease and Schizophrenia. Psychiatric and neurodegenerative disorders such as schizophrenia and Parkinson's disease are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate dopamine neuron activity by acting on acetylcholine receptors located on dopamine neurons. We aim to determine how these important recepto ....Central Muscarinic Receptors as Novel Drug Targets for Parkinson's Disease and Schizophrenia. Psychiatric and neurodegenerative disorders such as schizophrenia and Parkinson's disease are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate dopamine neuron activity by acting on acetylcholine receptors located on dopamine neurons. We aim to determine how these important receptors regulate dopamine neuron activity using genetically modified mice deficient in acetylcholine receptors, together with newly developed physiological methods and new acetylcholine receptor drugs. These studies will foster the design of novel acetylcholine receptor drugs as effective pharmaceutical treatments of neurological and psychiatric disorders related to brain dopamine dysfunction.Read moreRead less
Muscarinic Receptor Regulation of Dopamine Reward Pathways in the Brain. Human disorders such as schizophrenia and drug addiction are linked to alterations in the activity of neurons in the brain containing the chemical dopamine.

Human disorders such as schizophrenia and drug addiction are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate the activity of dopamine neurons by acting on acetylcholine receptors located on dopamine neurons. We aim to examine how dopamine neuron activity is regulated by these receptors using newly developed physiological methods together with a new acetylcholine receptor drug. We also aim to assess the suitability of mice genetically modified to be deficient in acetylcholine receptors as animal models of dopamine dysfunction related to schizophrenia and drug addiction.Read moreRead less
