This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography dat ....Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography data from Australian 3-D fossil fishes, combined with study of rare tetrapod gill arch bones, would enable us to determine the origins of tetrapod air-breathing and its ecological setting. The project may facilitate a rewriting of vertebrate evolution's most significant first step.Read moreRead less
Violence, Religion and Well-being in Contemporary Burma (Myanmar): A Medical Anthropological Study of Everyday Life Under Dictatorship. For 40 years, Burma has been controlled by a military dictatorship with human rights abuses occurring daily. Terror and political violence are used as tools of repression. An in-depth ethnographic study will be conducted into the relationship between emotional/psychological distress and the violence and fear that pervades everyday Burmese life. The project will ....Violence, Religion and Well-being in Contemporary Burma (Myanmar): A Medical Anthropological Study of Everyday Life Under Dictatorship. For 40 years, Burma has been controlled by a military dictatorship with human rights abuses occurring daily. Terror and political violence are used as tools of repression. An in-depth ethnographic study will be conducted into the relationship between emotional/psychological distress and the violence and fear that pervades everyday Burmese life. The project will test the hypothesis that religion plays an important role in mediating responses to fear. No other study has been conducted of everday life under this dictatorship, or of survival strategies created to alleviate fear. Outcomes will include refereed articles, a major monograph on the subject and the development of a new methodology appropriate for aiding victims of terror and torture.Read moreRead less
A unified model of amino acid homeostasis. This project aims to develop a unified model of amino acid homeostasis in mammalian cells and apply it to brain cells. The model will be underpinned by a mathematical algorithm that allows predicting amino acid levels in the cytosol based on fundamental parameters such as transport and metabolism. This project should provide the significant benefit of enabling the prediction of essential functions such as cell growth and survival.

Structure and function of heterodimeric amino acid transporters. Recently a new family of amino acid transporters has been identified, the members of which are involved in the delivery of amino acids between cells and tissues. All members display a rather unusual structure in that they require two subunits to be functional. The main aim of this study is to investigate the interaction between large and small subunits. The study will give insight how membrane proteins form complexes in the membran ....Structure and function of heterodimeric amino acid transporters.

This project explores articulations and experiences of health and illness among women in rural PNG, in light of the spread of HIV/AIDS in these communities. It examines the incorporation of new diseases, like HIV/AIDS, into Gogodala women's conceptualisations of sickness and health, arguing that in-depth analyses of cross-cultural notions of disease are vital for the provision of effective health care. Given HIV's rapid spread into rural communities, and its devastating effects on women and children in PNG, the project seeks to provide ethnographically-informed material that contributes to the development of regional health care policies and programs.Read moreRead less
Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromoso ....Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromosomes at mitosis, meiosis and in sperm. I will use immunohistochemistry to clarify chromosome pairing and recombination at meiosis. This will answer some important general questions about chromosome behaviour and sex chromosome evolution.
