The goal of this research is to improve outcomes for people at risk of becoming blind or visually impaired. The focus is on those who require a corneal transplant, or who suffer from inflammatory eye disease or painful disease of the ocular surface, on neonates with retinopathy of prematurity, or those with the eye disease, keratoconus. We will investigate new treatment options for eye diseases and will examine the evidence for the success of surgical and other therapeutic interventions.
I am a physiologist-pharmacologist examining fundamental mechanisms of chronic inflammatory disease. By defining these mechanisms, I seek to discover the underlying cause of disease and to identify novel strategies for diagnosis and therapy of chronic diseases that are worldwide causes of morbidity and mortality.
In a human body, about a million cells are born every second, and a million die by activating a physiological cell death mechanism. If cell death fails to occur, cells accumulate and can develop into cancers. Determining the mechanism and regulation of physiological cell death will provide novel approaches to treat cancers and auto-immune diseases, both of which are characterised by failure of certain cells to die.
Regulation And Mechanisms Of Cell Cycling, Cell Senescence And Cell Death

Summary
Most of our cells are not dividing, but persist in a stable arrested state, yet little is known of the molecular mechanisms that regulate and maintain permanent arrest, or that go wrong when cells start proliferating and turn into cancers. This proposal addresses an area of fundamental, basic biology, that has been largely overlooked. A better understanding of the molecules that regulate cell stability might provide new drug targets so that tumour cell proliferation can be stopped.
Mechanobiology Of Epithelial Homeostasis In Health And Disease

Summary
Epithelial tissues, such as the lung, fundamentally protect the body from its external environment. For this, they must detect and respond to danger. My work has discovered a new biological system where cells monitor changes in mechanical forces as a sign of danger. Diseases such as inflammation and cancer occur when this detection system fails. This Fellowship builds on my lab’s pioneering work to understand how force is used to sense danger, and how disease occurs when it goes awry.
This fellowship support will allow A/Prof Xiao-Jun DU to pursue his recent pre-clinical research findings on novel therapeutic interventions for cardiovascular diseases. He will particularly focus on new treatment of accumulation of excessive scar tissues (fibrosis) in the heart and large arteries following disease and cardiac inflammation, factors knowing to play pivotal roles in progression of cardiovascular diseases.

Summary
My research focuses on preventing and treating atherosclerotic disease and its complications such as heart attack and stroke. This will be achieved by developing new imaging technologies, with the aim to detect unstable atherosclerotic plaques, as well as innovative new drugs preventing inflammation and thrombosis as the major contributors of heart attack and stroke.
Understanding And Improving Treatment Of Premature Infants To Improve Long Term Outcomes

Summary
The last 2 decades heralded many important advances in the care of preterm infants but important gaps in our knowledge remain. Studies undertaken in the preclinical and clinical settings during this Fellowship will enhance understanding of the complex nature of disease in preterm infants. Further, we will develop and evaluate new treatments that enhance growth and development of the premature baby to optimise their long term intellectual, physical, emotional and social outcomes.
There are two arms to the immune system, one that learns and adapts, which can cause autoimmune disease, and another that is immediate and innate, and can cause autoinflammatory disease. This proposal continues our work in the characterization of rare genetic autoinflammatory disesaes and extrapolates these studies to more common chronic inflammatory diseases. This stands to improve current diagnosis and treatment, and elucidate future drug targets that could be targeted clinically.
My research is directed to the prevention of diabetes, across the spectrum from type 1 to type 2 diabetes. It is based on understanding immune-inflammatory mechanisms that contribute to dysfunction and death of pancreatic insulin-secreting beta cells and tissue resistance to the action of insulin. I study these mechanisms in rodent models and in humans in the context of relevant environmental factors and genes, with the aim of manipulating them for therapeutic benefit.
