Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and ....Tuneable “Nano-Shearing”: An Innovative Mechanism for the Accurate and Specific Capture of Cells and Molecules. Recent investigations have discovered a tuneable electro-hydrodynamic force which drives lateral fluid motion within a few nanometers of an electrode surface. Because the magnitude of this fluid shear force can be tuned externally (for example, via the application of an AC electric field), it provides a new capability to physically displace weakly (non-specifically) bound cellular and molecular analytes. By performing research to further understand and develop this tuneable effect, this project aims to build and test a new platform technology to enable highly efficient capture and specific detection of low concentration pathogenic molecules and circulating tumour cells (CTCs).Read moreRead less
Goodness-of-fit Testing Of Log-link Models For Categorical Outcome Data
Funder
National Health and Medical Research Council
Funding Amount
$260,863.00
Summary
Information about the health consequences of exposure to causal factors is obtained from mathematical models of observed data. Incorrect inferences are possible if the model does not adequately represent the data. Relative risk models are recommended for observations over time on a cohort of subjects, but it is not known how best to assess the adequacy of such models. This project will assess the performance of summary measures of goodness-of-fit when applied to relative risk models.
Design And Analysis Of Interrupted Time Series Studies In Health Care Research: Resolution Of Methodological Issues
Funder
National Health and Medical Research Council
Funding Amount
$307,125.00
Summary
An interrupted time series (ITS) study involves a population observed on multiple occasions before and after the implementation of an intervention program. However, methods for statistical analysis and designing such studies have not been well developed and many statistical analyses of such studies are flawed. This proposal will investigate appropriate methods for design and analysis, and develop guidelines and software for its implementation by health researchers.
STEP: Improving The Evaluation And Use Of Tests For Screening, Diagnosis And Monitoring In Healthcare.

Summary
Medical tests - for screening, diagnosis, and monitoring - are often poorly evaluated and poorly used. This program, run by an established team with skills in public health, clinical epidemiology, biostatistics, health economics and behavioural science, addresses the under-researched issues of whether, when and how to use medical tests. The elements of the program follow the sequence in which testing is often done: for screening (early detection), for diagnosis on which to base treatment decisio ....Medical tests - for screening, diagnosis, and monitoring - are often poorly evaluated and poorly used. This program, run by an established team with skills in public health, clinical epidemiology, biostatistics, health economics and behavioural science, addresses the under-researched issues of whether, when and how to use medical tests. The elements of the program follow the sequence in which testing is often done: for screening (early detection), for diagnosis on which to base treatment decisions, and for monitoring the effects of treatment. A common approach throughout is the identification of the benefits and harms of testing and assessing their trade-offs; how benefits weigh up against harms. This research is relevant to all partners in healthcare - consumers, clinicians and policymakers - who currently are being tested or implementing tests without being fully informed about the accuracy and effects of these tests.Read moreRead less

This project aims to develop a novel device, comprising advanced single molecule imaging, microfluidics and immunoassay technologies, for quantification of milk protein variants. Milk quality is central to dairying and variants of proteins in milk affect its market value. No current milk protein detection technologies are readily applied in milk production quality control. This project aims to produce a device that can be used by milk producers and farms to profile protein variants with high sensitivity in a single test in an hour and screen unwanted protein contamination. The platform also has great potential for detecting other complex and low content analytes. It builds on innovations in nanoparticles and recent industry collaboration.Read moreRead less

Translating Molecular Pathology Into Cancer Diagnostics

Funding Amount
$2,285,520.00
Summary
Precision oncology, the treatment of cancer patients selected with a particular molecular characteristic (biomarker) matched to a therapy, has transformed the treatment of cancer patients. However, many biomarkers used for clinical care are not reliable and do not perform their role. I will translate new research tests from fundamental discovery, clinical trials and the development of novel diagnostics using innovative high throughput laboratory technologies to enhance patient outcomes.
