Food allergies have emerged as a major public health concern affecting 1 in 10 Australian infants. Hospitals waiting times are in excess of 12-months for specialist services. Recent changes in the environment are driving up rates of food allergy but the mechanisms are unclear. Epigenetics is the science of how the environment influences gene behaviour. This fellowship will address the important and urgent question of how modern environments are changing our genes, leading to food allergy.
Ontogeny Of Toll (TLR) Function In Normal And Allergic Children: The Impact Of Microbial-rich Environments

Summary
Reduced exposure to bacteria during early life has become a leading candidate to explain the escalating rate of allergic disease. Despite this, the development and maturation of the pathways involved in normal recognition of bacteria in children has not been explored. In this proposal we set out to address this critical shortcoming in both normal and allergic children. Mapping normal maturation of such pathways will help us to identify better early markers of allergic disease.
Understanding Immunosuppressive Pathways In Cancer

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. Suppression can be mediated by cells of the immune system, or cancers themselves. My project aims to investigate 3 suppressive pathways and determine their hierarchy in different mouse models of cancer using mouse genetics and antibody-based treatment approaches. Understanding these processes ongoing in the cancer environment will allow the design of more effective cancer therapies.
Allergic disease affects more than one in five Australian children. What foods a mother eats during pregnancy and breastfeeding, as well as when to introduce solid foods to babies, is thought to be critical in reducing the increasing burden of allergies in our Australian community. I hope to use this fellowship to discover what dietary factors put children at risk of developing a food allergy, and ways we can reduce that risk.
Anaphylaxis: Pathophysiology, Acute Management, Diagnosis And Immunotherapy.

Funding Amount
$380,558.00
Summary
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. This award will support research projects that aim to improve both the emergency care of this condition and subsequent immunotherapy (desensitisation) for people who experience anaphylaxis to insect sting. It will also support research to better understand anaphylaxis to antivenoms, which is a major problem worldwide, and to thus improve the treatment of snake, scorpion and spider envenoming.
Diet And Mental Health: Translating New Knowledge Into Innovative Prevention And Treatment Strategies

Summary
I have pioneered the development of a robust body of evidence demonstrating the important role of diet in mental health and I am now recognised internationally as a research leader in this new field. The next important step is to translate this knowledge into new prevention and treatment strategies in order to address the substantial global burden of illness attributable to mental disorders.
Systems Immunology Of Antigen Specific T Cells: From Single-cell To Immune Protection
Funder

Funding Amount
$470,144.00
Summary
T cells are key for establishment of immune protection and object of ongoing research in vaccines and more recently immunotherapy against infections and some cancers. Their dynamics are complex and many mechanisms remain unknown that could be exploited for modern therapies. Here, in a systems approach I will combined single cell technologies, immunology and computational biology to identify the factors that determine the establishment of long term memory cells utilising a unique set of samples.
