Understanding The Factors Governing Susceptibility And Outcome In Childhood Infection

Summary
This research seeks to understand why a minority of children are prone to severe and often life-threatening infections and inflammation. It focusses on infections both in preterm infants and in later childhood, which may also be relevant to understanding atherosclerosis. I am also interested in improving the health of recently arrived refugees, by conducting research that allows the development of evidence-based health interventions and developing national policy on refugee health.
Tuberculosis - Transmission, Drug Resistance And Strain Emergence

Summary
Tuberculosis (TB) kills nearly 2 million people each year. The emergence of drug resistant TB in the Asia-Pacific region pose a particular threat to Australia, due to frequent population mixing and ongoing TB transmission that may facilitate its spread within vulnerable communities. The proposed study will develop advanced tools to monitor and limit TB transmission within Australia. It will also provide novel insight into the evolution of the global TB epidemic and key factors that sustain it.
Brown fat protects animals against obesity and diabetes. Humans with abundant brown fat are metabolically healthy. Identification of medication that boosts brown fat function may lead to novel treatment of metabolic disorders. This proposal will examine the role of such a medication, which is modeled on a factor (called FGF21) released from brown fat. The project will also search for other factors released by human brown fat, which may become future targets of obesity treatment.
Pneumococcal disease is one of the biggest killers of children under 5 years of age worldwide, mostly in developing countries. Pneumococcal conjugate vaccines are highly effective at reducing pneumococcal disease however the duration of protection and the immune factors involved is unknown, particularly when fewer than the recommended number of doses are used. My fellowship aims to examine the key immune factors that provide long-term protection following pneumococcal vaccination.
This study focuses on key endocrine pathways involved in the remodelling of the breast stromal cells into a reactive stromal environment which is more permissive for tumour growth. We have identified key pathways involved in the regulation of estrogen biosynthesis and fibrosis in tumour associated stroma. These studies will lead to the development of novel breast cancer therapies.
Understanding Typical And Atypical Development Of The Infant Brain

Funding Amount
$428,065.00
Summary
This project will apply advanced magnetic resonance imaging (MRI) techniques to understand how brain abnormalities in preterm infants relate to their functional impairments. It aims to: develop new software to easily and accurately measure infant brain structures and tissues; understand the neurobiological basis for adverse outcomes, enabling diagnosis of high risk preterm infants; and identify MRI biomarkers to assess interventions designed to give Australian babies a healthier start to life.
