About 45% of bladder cancer patients require radiotherapy or surgery. Radiotherapy has a failure rate of ~50%. Surgery (bladder removal) diminishes quality of life considerably. Modelling complex gene interactions in radiated cancer cells will provide crucial knowledge on the molecular genesis of radiotherapy-resistance of tumours. Our findings will provide: (i) an accurate mathematical/computational model for diagnosing radiosensitivity; (ii) further insights to be applied in the pharmaceutical sector such as the discovery of novel molecular targets that have the potential to increase radiotherapy success ratios; (iii) a holistic modelling technique applicable to a larger diversity of tumours.Read moreRead less
Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less

The research, when extended to protein registration, will facilitate analysis of DNA and advance research in bioinformatics and biotechnology. The research could also be used for target recognition, mosaic construction, content-based retrieval, in remote sensing and multimedia. Benefits to Australia include the provision of a readily adaptable image registration program for patient care (e.g., early detection of cancers, dementia), cutting-edge research, high-quality training for students, and encouraging international research collaboration.Read moreRead less

Fibre Optic Dosimeters for Medical and Environmental Applications. We will develop fibre optic dosimeters for environmental monitoring and radiation therapy. A novel approach using refractive index gradients will be used to capture scintillator light while rejecting noise. New knowledge will be gained of the mechanisms of radiation damage in scintillators and glasses. The small, flexible, accurate fibre optic dosimeters will be equivalent in absorbing characteristics to human tissue, making them ....Fibre Optic Dosimeters for Medical and Environmental Applications. We will develop fibre optic dosimeters for environmental monitoring and radiation therapy. A novel approach using refractive index gradients will be used to capture scintillator light while rejecting noise. New knowledge will be gained of the mechanisms of radiation damage in scintillators and glasses. The small, flexible, accurate fibre optic dosimeters will be equivalent in absorbing characteristics to human tissue, making them superior to all currently available dosimeters. Fibre optic dosimeters will enable new adaptive radiotherapy techniques and provide quality assurance of dose delivery in radiotherapy. Their multiplexing capability will lead to applications in monitoring of workplaces and aerospace environments.Read moreRead less
New Copper and Rhenium Radiopharmaceuticals. The aims of this project are to provide new metal-based radiopharmaceuticals for the treatment of cancer, and the imaging of cancer and other conditions through the design and engineering of new coordination complexes of rhenium and copper.

Functionalised MMP Inhibitors as Radiodiagnostic, Radiotherapeutic, and Radiation-Sensitising Agents for Metastatic Cancer. Identifying and treating malignant cancers is one of the major challenges facing the scientific and medical communities. In order to minimise side effects that accompany most treatments of cancer it is necessary to find ways of targeting the therapy to tumours and away from healthy organs. A difference between tumours and healthy tissues is the amount of the proteins (calle ....Functionalised MMP Inhibitors as Radiodiagnostic, Radiotherapeutic, and Radiation-Sensitising Agents for Metastatic Cancer. Identifying and treating malignant cancers is one of the major challenges facing the scientific and medical communities. In order to minimise side effects that accompany most treatments of cancer it is necessary to find ways of targeting the therapy to tumours and away from healthy organs. A difference between tumours and healthy tissues is the amount of the proteins (called MMPs) that tumours use to break out of their surroundings, to break into and out of the blood system, and to establish new colonies of cancer cells or metastases. This difference also distinguishes the most aggressive cancers. The purpose of this project is to develop means of identifying and targeting cancers using molecules that bind to these MMP proteins.Read moreRead less
Bayesian statistical models for understanding outcomes and improving decision-making for women screened for breast cancer.

This project has two key benefits: (i) the development of frontier statistical methods for spatio-temporal analysis and data synthesis, which are imperative in a wide range of disciplines; and (ii) the application of these methods for improved understanding of breast cancer outcomes for women screened in Queensland. The project results will lead to direct health and financial benefits through targeted policies for increasing screening uptake and reducing cancer morbidity and mortality and therefore health spending in this area. Importantly, the project represents an excellent training opportunity to develop a PhD candidate into an experienced interdisciplinary researcher.Read moreRead less
The development of tuneable materials to allow the three-dimensional printing of cells. New low cost three-dimensional (3D) printers and reagents will be developed during this project to allow cancer biologists to print cells and polymers as more realistic 3D tissue models for biological assays. Such technology will be important for performing basic research into cancers as well as for providing better tools for drug testing.
