This research will place Australia in the forefront of understanding and responding to the regional-scale impacts of climate change on tropical societies and economies.Read moreRead less
Understanding mechanisms of sex programming of cardiovascular development. The goal of this project is to track the influence of sex and sex hormones through crucial lifespan timepoints to define how specific patterns of gene signalling determine adult cardiovascular traits at cell, tissue and systems level. Sexually distinct cardiovascular traits are conserved across mammalian species. Early developmental events are known to be important in influencing later adult characteristics, but how adult ....Understanding mechanisms of sex programming of cardiovascular development. The goal of this project is to track the influence of sex and sex hormones through crucial lifespan timepoints to define how specific patterns of gene signalling determine adult cardiovascular traits at cell, tissue and systems level. Sexually distinct cardiovascular traits are conserved across mammalian species. Early developmental events are known to be important in influencing later adult characteristics, but how adult cardiovascular functions are ‘programmed’ differently for males and females is not understood. The project aims to uncover the importance of the placenta in regulating foetus exposure to sex steroids and the crucial effects of the pubertal hormone surge in shaping cardiovascular phenotypes of male and female offspring.Read moreRead less
Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus. The upper airway muscles, the most complex in the human body, are critical for breathing and speaking, but are not well understood. Genioglossus draws the base of the tongue forward to maintain airway patency. This project will study genioglossus during wakefulness and sleep in normal healthy individuals. It is anticipated that th ....Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus. The upper airway muscles, the most complex in the human body, are critical for breathing and speaking, but are not well understood. Genioglossus draws the base of the tongue forward to maintain airway patency. This project will study genioglossus during wakefulness and sleep in normal healthy individuals. It is anticipated that the project will suggest improved avenues for treatment of sleep related respiratory disorders.Read moreRead less
Enhancing sunscreen DNA and photo-ageing protection. Skin damage from UV exposure is costly for individuals and the community, particularly in Australia, where the population has predominantly fair skin. While public campaigns to persuade the population to use sun protection and avoidance have been useful, this project will be the first to extend this approach to deliver a way to reduce sun damage from any UV exposure that does nevertheless occur, by incorporating the active agents into topical ....Enhancing sunscreen DNA and photo-ageing protection. Skin damage from UV exposure is costly for individuals and the community, particularly in Australia, where the population has predominantly fair skin. While public campaigns to persuade the population to use sun protection and avoidance have been useful, this project will be the first to extend this approach to deliver a way to reduce sun damage from any UV exposure that does nevertheless occur, by incorporating the active agents into topical sunscreens or creams for after-sun use. The project will also build infrastructure for translational research on photo-damage, combining world-class facilities for this research with advanced formulation and manufacturing operations.Read moreRead less

Summary
The role of deep-sea microorganisms in nutrient cycling in the Southern Ocean. This project aims to learn how surface water microbes that are important in global nutrient cycling adapt to life when they sink to the deep sea. This will teach us about the roles that surface water and deep sea microbes play in maintaining the health of marine environments.
Packed to perform: the effects of telomere traits and free radicals on sperm phenotypes, fertilization success, and offspring viability. This project will integrate telomeres, free radicals and sperm biology into a coherent research program on the roles of free radicals in eroding telomeres and dictating: success in sperm competition and cryptic female choice; longevity and life time fitness in the wild; and, transgenerational effects on offspring viability, in particular mediated via paternal t ....Packed to perform: the effects of telomere traits and free radicals on sperm phenotypes, fertilization success, and offspring viability. This project will integrate telomeres, free radicals and sperm biology into a coherent research program on the roles of free radicals in eroding telomeres and dictating: success in sperm competition and cryptic female choice; longevity and life time fitness in the wild; and, transgenerational effects on offspring viability, in particular mediated via paternal telomere length. Specifically, the project researches how sperm telomere length in sires shorten under stress and how this epigenetic effect is transferred from sires to sons and potentially moderates also filial success in sperm competition and attractiveness in cryptic female choice.

Proteomic techniques to assess oxidative stress in muscle wasting diseases. Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits. Oxidative stress ....Proteomic techniques to assess oxidative stress in muscle wasting diseases. Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits. Oxidative stress is a key intermediary in muscle wasting. This PhD project examines a possible mechanism by which oxidative stress causes muscle wasting. An appropriately tailored therapy to minimise oxidative stress has the potential to ameliorate loss of muscle mass.

Evolutionary proteomics of social insects. This project aims to understand the molecular mechanisms that affect fertility in honeybees and leaf-cutting ants by identifying the function of proteins in male and female secretions related to insemination and sperm storage. The understanding of these general principles will have important applications for honeybee breeding.
Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal ....Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal can induce a neural memory that is not inhibited by usual stimuli. The findings are expected to increase our understanding of normal human functioning but may also have implications for conditions where upper airway muscles are important such as dysphagia, sleep apnea and numerous other sleep disorders.Read moreRead less
Sterile inflammation as a determinant of adaptive immunity. When we injure ourselves, the site of injury becomes inflamed, which may help healing or cause trouble. This project aims to understand how the normal response to injury is controlled and why the process may sometimes go wrong.
