Summary
Type 1 diabetes affects more than 140,000 Australians and up to 40% of children and adolescents with the disease develop complications including kidney disease. Excess blood sugar as the result of diabetes can accelerate a biochemical process called advanced glycation, which permanently alters proteins affecting their structure and function, which I have previously shown as contributors to kidney damage in diabetes. Recently, however, I have discovered that this biochemical process is also invol ....Type 1 diabetes affects more than 140,000 Australians and up to 40% of children and adolescents with the disease develop complications including kidney disease.

Summary
Type 2 diabetes is associated with reduced levels of the hormone insulin that results in an increase in blood sugar. Evidence suggests that when the cells that make insulin are overworked they fail to produce the right amount of this hormone to keep blood sugar levels normal. In this proposal we will determine how overworking the insulin producing cells damages them and assess whether reducing the need to overwork is beneficial and thus lead to reduced blood sugar levels in Type 2 diabetes.
Most common diseases of ageing like diabetes and cancer have proven intractable because much of our knowledge is limited to individual molecules. This proposal takes a global approach to complex diseases, utilising quantitative high-resolution methods and computational modelling. This research will lead to a completely new way of thinking about complex diseases providing a range of completely novel treatment options.
In patients predisposed to metabolic diseases, excessive fats get delivered to various tissues. About 10 to 15% are converted into sphingolipids, many of which have deleterious effects on tissue function. Blocking sphingolipid production prevents diabetes and most cardiovascular diseases in rodents. We seek to better understand these mechanisms and determine how the observations can be translated into new therapies and better clinical outcomes.
Helminth Secreted Proteins – From Anthelmintic Vaccines To Therapies For Autoimmunity

Summary
Human helminths (worms) cause chronic disease in developing countries, yet their disappearance from developed countries has been accompanied by an increase in the prevalence of autoimmune and allergic diseases. My resesarch focuses on the proteins these worms secrete and their use in (1) the development of anthelmintic vaccines, and (2) the development of novel anti-inflammatory molecules to treat autoimmunity, particularly diseases affecting the gut.
Diabetes And Obesity: From Benchtop To Public Health

Summary
Obesity. Novel factors, not related to food intake or physical activity, will be explored as possible causes of obesity. The obesity paradox, in which overweight is associated with reduced mortality, will be examined. Diabetes treatment. Methods will be developed to predict which is the right drug for each individual patient. A study will test the use of nurse-led clinics. A novel insulin delivery mechanism will be developed. Novel causes and consequences of diabetes will be explored.
Obesity is associated with type 2 diabetes, fatty liver disease, cardiovascular disease and cancer. These inter-related diseases reduce life expectancy and their treatments come at an enormous financial cost. The overriding aim of this work is to understand the molecular and cellular regulation of lipid metabolism in skeletal muscle, liver and adipose tissue, and how this impacts endocrine function to affect the pathogenesis of types 2 diabetes and prostate cancer.

Summary
Diabetes is a major health epidemic & diabetic complications are a major cause of morbidity and mortality in our community. My studies have increased our understanding of how inflammation contributes to diabetes but also directly led to the discovery of novel therapies that are been trialed in patients with type 1 diabetes undergoing islet cell transplants. My studies have increased our knowledge of the factors that lead to type 1 diabetes and the development of new treatments.
Understanding the basic biology of cells will allow us to pinpoint key mechanisms and molecules that underpin multiple diseases and are targets for treatments. The broad aims of this research program include the development of new therapies for chronic inflammatory diseases, understanding how proteins are sorted and trafficked inside cells in processes that are essential to immunity and cancer biology, and identifying new intracellular targets to block bacterial invasion and infectious diseases.
