Attrition in longitudinal studies: advancing and evaluating statistical methods. Longitudinal studies are a vital tool for monitoring the health and well-being of Australians. They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset. There have been many successful longitudinal studies in Australia that have lead to significant breakthroughs in evidence-based health (e.g. the Nambour Skin Cancer Prevention Trial). Unfortunatel ....Attrition in longitudinal studies: advancing and evaluating statistical methods. Longitudinal studies are a vital tool for monitoring the health and well-being of Australians. They are uniquely placed to examine changes in diseases over time and prospectively collect data on exposure and disease onset. There have been many successful longitudinal studies in Australia that have lead to significant breakthroughs in evidence-based health (e.g. the Nambour Skin Cancer Prevention Trial). Unfortunately all longitudinal studies suffer from attrition, or loss of participants, which leads to questions concerning their validity and generalisability. This project will investigate the causes of attrition, and the effect attrition has on longitudinal studies, in order to improve their design and analysis.Read moreRead less
Short sleep as a cause of obesity: a longitudinal examination of Australian children and adults. This project will examine whether short sleep durations predict weight gain and obesity in Australian children and adults. The findings will have potentially important implications for how obesity is treated and prevented in Australia.
Targeting early contact with the criminal justice system in young people. This project aims to identify who and why young people first come in contact with the criminal justice system and what determines the early course of contact. The project will focus on first police contact, as a victim, witness or offender, as a means of identifying young people at-risk of adverse life outcomes. It intends to build on the NSW Child Development Study, a large population-based intergenerational cohort, to de ....Targeting early contact with the criminal justice system in young people. This project aims to identify who and why young people first come in contact with the criminal justice system and what determines the early course of contact. The project will focus on first police contact, as a victim, witness or offender, as a means of identifying young people at-risk of adverse life outcomes. It intends to build on the NSW Child Development Study, a large population-based intergenerational cohort, to develop services and interventions aimed at preventing young people from becoming enmeshed in the criminal justice system.Read moreRead less
Min/Max Autocorrelation Factors in Time Series Studies of the Adverse Health Effects of Ozone. The annual health costs associated with exposure to air pollution in Australia have been estimated at between $3 and 5.3 billion. Given these costs, it is vital to conduct research that ensures public health officials and policy makers stay fully informed of Australia’s air pollution problem. The project proposes to address this need by developing methodology to detect trends in air pollution concentra ....Min/Max Autocorrelation Factors in Time Series Studies of the Adverse Health Effects of Ozone. The annual health costs associated with exposure to air pollution in Australia have been estimated at between $3 and 5.3 billion. Given these costs, it is vital to conduct research that ensures public health officials and policy makers stay fully informed of Australia’s air pollution problem. The project proposes to address this need by developing methodology to detect trends in air pollution concentrations and reduce measurement error in recorded air pollution concentrations. This will enable relevant authorities to produce more accurate estimates of air pollution health costs and implement more appropriate pollution regulations and health warnings.Read moreRead less
Allocating scarce HIV/AIDS antiretroviral drugs in resource-constrained countries: using modelling to develop tools and analyse consequences of ethics and HIV-epidemiology. This project will benefit communities in some of the poorest countries of the world, suffering greatly from the HIV/AIDS epidemic. This research is important and timely for these nations in deciding how to distribute the limited treatment in an ethical manner to address treatment principles of these countries. However, the me ....Allocating scarce HIV/AIDS antiretroviral drugs in resource-constrained countries: using modelling to develop tools and analyse consequences of ethics and HIV-epidemiology. This project will benefit communities in some of the poorest countries of the world, suffering greatly from the HIV/AIDS epidemic. This research is important and timely for these nations in deciding how to distribute the limited treatment in an ethical manner to address treatment principles of these countries. However, the methods developed can also be applied to other diseases in different regions and people, such as Australian aborigines to increase their quality of health. Specifically, an epidemic of Chlamydia is widespread amongst the aboriginal communities of Australia's Northern Territory. Tools developed in this project will be easily adaptable to address control measures for Chlamydia among this population. Read moreRead less
An investigation of illicit tobacco use - its prevalence, economic impact and the motivations and perceptions of consumers. Black market tobacco costs the Australian government at least $450 million in lost taxes per annum. Little is known about the prevalence and economics of illicit tobacco use, or the motivations, attitudes and perceptions of consumers. Using a national telephone survey of licit and illicit tobacco consumers, we will investigate their economic thresholds, decision-making pr ....An investigation of illicit tobacco use - its prevalence, economic impact and the motivations and perceptions of consumers. Black market tobacco costs the Australian government at least $450 million in lost taxes per annum. Little is known about the prevalence and economics of illicit tobacco use, or the motivations, attitudes and perceptions of consumers. Using a national telephone survey of licit and illicit tobacco consumers, we will investigate their economic thresholds, decision-making processes, and perceptions of health effects. Our work will lead to improved supply and demand reduction measures for illicit tobacco, and enable development of appropriately targeted health promotion strategies, generating enduring benefit to Australia's economy and public health.

Understanding spatial trends in HIV/AIDS infections in South Africa and Australia. This project will develop quantitative methods that will be used to inform public health officials in understanding past and current HIV/AIDS epidemics as well as planning for the future of these epidemics. It will understand not only the behavioural and demographic characteristics of importance as risk factors for HIV infection in South Africa, the epicentre of the global HIV pandemic, but also the geographical s ....Understanding spatial trends in HIV/AIDS infections in South Africa and Australia. This project will develop quantitative methods that will be used to inform public health officials in understanding past and current HIV/AIDS epidemics as well as planning for the future of these epidemics. It will understand not only the behavioural and demographic characteristics of importance as risk factors for HIV infection in South Africa, the epicentre of the global HIV pandemic, but also the geographical spatial locations in which HIV cases are likely to emerge in the future. This project will also forecast the future geographical trends in Australia's changing HIV epidemic in order to plan for intervention strategies and prepare clinical practice appropriately.Read moreRead less

The benefits of this project are better preparedness for the ever-present threat of infectious disease spread and the stimulation of bioinformatic research in Australia. Epidemics such as the Influenza Pandemic of 1918, which killed over 20 million people, highlight the need to understand and track pathogens that can potentially cause such devastation. Along with the development of molecular technologies, it is important to maintain active creation of analytical methods that appropriately apply to growing databases. These include methods to understand genetic variation in pathogens. This project will help to keep Australia at the forefront of research in theoretical biology.Read moreRead less
