Funding Amount
$487,258.00
Summary
Australia has experienced a prolonged epidemic of pertussis from 2008 to 2012 and is currently experiencing another epidemic. In this project, we aim to elucidate the evolutionary dynamics of the epidemics by genome sequencing and develop a practical high throughput culture independent method for epidemiological typing. The outcomes will be highly significant for surveillance of pertussis infections and designing strategies for control and prevention of pertussis.
Rapid Plasticity In Sensory Systems - Linking Neuronal Adaptation And Perception

Funding Amount
$650,810.00
Summary
The activity of individual sensory neurons in the brain is surprisingly variable and continuously changing. It is unclear how reliable perception of the world can be generated from the activity of “noisy” neurons, and it remains unclear why neuronal sensitivity should change in the first place! This project will give insights into how groups of sensory neurons collectively overcome their intrinsic variability to support reliable visual perception.
Context Is Everything – Understanding How Spatial, Temporal And Behavioural Context Affect Sensory Processing

Funding Amount
$512,382.00
Summary
A possum in a tree is cute to see on a bushwalk, but scary to hear when we are trying to sleep. This illustrates that how we perceive a “target” is affected by “modulators” that are close in space or time to the target, or by the task at hand. Deficits in contextual modulation are apparent in many neurological conditions. This project will investigate the neural circuitry that mediates spatial, temporal and task-related contextual modulation.
Forecasting The Impact Of Climate Change On Dengue Transmission

Summary
Dengue fever (DF) is the most important mosquito-transmitted viral disease in the world. The large-scale re-emergence of DF in the Asia-Pacific region during the past few decades has renewed its status as a serious international public health problem. Global climate change is anticipated to impact upon the biology and ecology of vectors and consequently the risk of DF transmission. The principal research aim of this study is to project the impact of future climate change on DF.
In pilot studies, we have found that specific genes are modulated by long-term alcohol intake in a discrete part of the brain that drives habitual behaviours. We will now repeat these studies in post-mortem brain tissue from human alcoholics and age-matched controls. In addition, we will further characterise the functional consequences of long-term alcohol intake within this specific brain region and test new approaches to reduce the urge to consume alcohol.
A New Mouse Model That Determines The Effects Of A Unilateral Vestibular Prosthesis On Vestibular Plasticity.

$455,678.00
Summary
Much like a cochlear implant restores auditory function, a vestibular prosthesis restores balance function. It is not clear whether the limited results from vestibular prostheses is due the device not stimulating one component (the otoliths) of the vestibular system essential for self-repair. We will test mutant mice that lack otoliths to determine the importance of stimulating the otoliths in restoring function. This work will shape the future direction of prosthesis development.
Evolutionary Response Of Dengue And Chikungunya Viruses To A Novel Biocontrol Method

Summary
Dengue and chikungunya are mosquito-transmitted viruses that present significant public health threats to Australia and the Asia-Pacific. This project will investigate whether dengue and chikungunya can adapt in response to a bacterium that limits replication of the viruses in the mosquito. The research will provide critical data to inform new mosquito control methods aimed at breaking the virus transmission cycle. More broadly, the research will allow us to understand how viruses adapt to strat ....Dengue and chikungunya are mosquito-transmitted viruses that present significant public health threats to Australia and the Asia-Pacific.

Understanding Pathogen Effects On Human T Cell Receptor Diversity And Function

Funding Amount
$808,693.00
Summary
HIV diversity observed at the global level is mostly due to the selection pressure exerted on the virus by our adaptive immune response. This process is important in determining infection outcome. This proposal will use a unique single cell approach to understand this complex host-viral interaction to identify important correlates of immune efficacy against HIV that will aid in the rational design of potential vaccine candidates and addresses a fundamental concept in anti-viral immunity.
Identifying Optimal Sustainable Cooling Strategies For The Most Vulnerable During Heatwaves

Funding Amount
$1,115,640.00
Summary
Current guidance warns against electric fan use in heatwaves without any supporting evidence. This Project aims to identify how fans and other parallel low-resource strategies can reduce the risk of heat-related illness in the most vulnerable during simulated hot/humid and very hot/dry heat wave conditions. This information will be used to develop simple heat adaptation strategies that also mitigate unsustainable energy demands and the destructive environmental impact of air conditioning.
New Vectors, New Diseases: Understanding The Risk Of Chikungunya Transmission In Australia
Funder
National Health and Medical Research Council
Funding Amount
$522,580.00
Summary
Chikungunya is a febrile illness that can lead to chronic, debilitating joint pain in adults and severe neurological complications in children. Introductions of this virus into Australia have steadily increased in recent years. We will estimate the risk of chikungunya transmission in Australia now and into the future, and deliver the results to public health authorities to reduce the risk of outbreaks in Australia.
