Summary
Pulmonary nodules may represent early lung cancer though difficulty in accurate diagnosis means many patients experience delayed diagnosis, or unnecessary surgical biopsy or repeat CT imaging (& consequent radiation exposure). I will identify molecular (DNA, protein) markers in bronchoscopic & blood specimens to accurately characterize malignant & benign nodules. These biomarkers will also be investigated for their value as a non-invasive screening test for lung cancer
The Effect Of Heterogeneity And Airway Closure On Distensibility Measurements In Asthma

Summary
Long term asthma can result in stiffening of the airways, which cannot currently be measured with standard lung function tests. A new non-invasive technique, using sound, has been shown to measure airway stiffness, but this may be adversely influenced by other respiratory changes that occur with asthma (airway closure, heterogeneity). We are investigating the effects of these confounding factors to fully characterise this novel technique, so that it can be used in the clinical environment.
Supporting Informed Choice For Management Of Screen Detected Ductal Carcinoma In Situ (DCIS) Among Older Women (70 Years And Over)

Summary
DCIS refers to abnormal changes in the breast that may or may not lead to breast cancer later on. Screening women over 70 means more DCIS will be found and treated by surgery, radiotherapy, and other treatments. To avoid unnecessary treatment, some DCIS patients could instead have regular checks (monitoring). This research will develop a tool to help women over 70 with DCIS to make an informed choice between monitoring or immediate treatment, and test whether this improves their quality of life.

Summary
Genetic defects are the major cause of embryonic and foetal death as well as being responsible for a large proportion of childhood disabilities. Although many are detected by the ~50,000 prenatal tests currently performed annually in Australia, these methods are only offered to high risk mothers because they are invasive (~1% risk of miscarriage), and-or expensive.

Although many are detected by the ~50,000 prenatal tests currently performed annually in Australia, these methods are only offered to high risk mothers because they are invasive (~1% risk of miscarriage), and-or expensive. A rapid, low cost, less invasive and safer alternative prenatal diagnostic method such as PAP smears that could be offered to all mothers regardless of risk is therefore of immense value both to mothers and to the health care system. This proposal enhances first trimester screening by improving prenatal diagnosis from PAP smears. Although normally taken to detect cancer, these smears contain significant numbers of foetal cells. We will investigate: the best way and time to obtain these cells, the best way to remove the cells from any contamination, improvements in genetic diagnosis of these cells using a technique known as MF-PCR which is rapidly revolutionising conventional prenatal diagnosis. By automating these procedures, they will become less expensive and more accessible to all mothers regardless of risk. We will also compare these procedures with alternative first trimester screening techniques such as nuchal translucency to determine the value of both tests singly and in combination. This research should provide a safe, reliable and accurate method allowing inexpensive prenatal screening to be available for all pregnancies. General screening programmes using this new test, particularly if combined with nuchal translucency programmes, would result in a dramatic reduction in affected babies with major implications to families and the health care system.Read moreRead less
Nanoparticle-based Anti-VEGF Treatment For Ocular Neovascularization

Summary
Diseases like AMD and DR are the leading cause for substantial and irreversible vision loss as a direct effect of pathologic ocular neovascularization and have a significant economic impact on individuals, families, health systems and countries. Nowadays, the treatment requires frequent intravitreal injections of anti-VEGF antibody with all the risks of an invasive intraocular procedure. Nanotechonoly-based drug delivery system will provide a less invasive treatment for this kind of disease.
