SGLT2 inhibitors are new glucose-lowering agents for type 2 diabetes. They promote glucose loss into urine, which lowers blood glucose levels. However, little is known regarding the changes to kidney physiology when this system is manipulated with these drugs. There is evidence that SGLT2 inhibitors do not protect against kidney disease in diabetic mice, despite being an effective blood glucose-lowering agent. I aim to characterise the changes to kidney function upon SGLT2 blockade in diabetes.
Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle ....Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle and adipose tissue by stimulating the movement of a glucose transport protein from inside the cell to the cell surface (see http:--www.imb.uq.edu.au-groups-james-glut4 for an animated description of this process). The purpose of this proposal is to dissect the molecular mechanisms by which this glucose transporter can be held inside the cell in the absence of insulin and then allowed to be released from this site moving to the surface in the presence of insulin. Our studies over the past 5 years have brought us much closer to understanding this process in detail. The identification of the molecules responsible for this regulatory step will not only aid our understanding of this process but it will also provide a valuable target for development of therapeutic agents that can be used to combat insulin resistance.Read moreRead less
It’s The Amount That Counts: The Impact Of Seven Days Of Sleep Restriction On Predictors Of Type 2 Diabetes.

Summary
The aim of this project is to examine the relationship between sleep duration (5, 6, 7, 8, or 9h per day for one week) and glucose metabolism. This will allow us to quantify the amount of harm that different levels of sleep loss cause to the physiological systems that protect people from developing serious health disorders. In particular, the results of the project will be invaluable in the design of effective behavioural interventions for the prevention and/or treatment of type 2 diabetes.
Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repa ....Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repairs. Towards this end, this project will develop an innovative structural health monitoring system to monitor and maintain the structural health of our bridges. The project outcomes will have immediate applications in Australia and overseas with economic and social benefits to the community.Read moreRead less
Optimisation of Rail Network Infrastructure Capacity under Dynamic Train Planning. Recent changes in railway operating environments have caused significant operational and management problems in Australia.

Recent changes in railway operating environments have caused significant operational and management problems in Australia. This research will lead to improvements of railway's key managerial functions, namely: network capacity planning; rollingstock planning; train scheduling; and maintenance planning. The major outcome of the research will be to develop an optimisation model to significantly improve the operating efficiency and assets productivity of Australia's rail system. The novelty of the research is that it will be undertaken using innovations based on modern job shop scheduling and sequencing optimisation techniques as the complexity of the problem makes it impossible to solve by classic optimisation techniques.Read moreRead less
Wave Climate in the Southern Great Barrier Reef. Sea surface roughness has a major influence on global climate modelling. This project will provide a better understanding of the variability of sea waves in coastal waters. New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, a ....Wave Climate in the Southern Great Barrier Reef.

New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, and evaluate focussing of waves by complex currents on the continental shelf to help improve wave forecasting in coastal waters. The HF radar will be used to experimentally test current theories of wind wave spreading.Read moreRead less
Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users.

Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such vehicles in regional centres by producing: (1) an assessment methodology to deal with options for network efficiency gains which will capture the full impacts; and (2) a computer modelling tool based on fundamental research to quantify those impacts, in terms of delays and accident rates.Read moreRead less

Funding on the line: public transport financing and property value capture. This project aims to develop property value capture schemes that would provide alternative funding for public transport infrastructure. It plans to model the timing and spatial patterns of property value uplift from recent investments in rail, busways and ferries in Queensland and New South Wales. It then intends to conduct a survey of Australian stakeholders and discrete choice modelling to determine willingness-to-pay. ....Funding on the line: public transport financing and property value capture.
