Analysing and modelling molecular rate variation among nuclear and mitochondrial genomes. My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise.

My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise. The research will provide important insights into the rates and patterns of genetic changes associated with domestication, and into variation in evolutionary rates among the primate ancestors of humans. In addition to developing new software, which will be made publicly available, I will develop new evolutionary models to supplement existing software packages. Read moreRead less
Molecular identification of blowflies of forensic importance and thermal effects on their behaviour: tools to enhance forensic entomology in Australia. In suspicious deaths in which a body is found three or more days post-mortem, carrion-breeding blowflies provide time since death estimates. These estimates are currently slow and relatively broad due to (a) an inability to adequately distinguish immatures morphologically, and (b) insufficient information on the biological responses of different ....Molecular identification of blowflies of forensic importance and thermal effects on their behaviour: tools to enhance forensic entomology in Australia. In suspicious deaths in which a body is found three or more days post-mortem, carrion-breeding blowflies provide time since death estimates. These estimates are currently slow and relatively broad due to (a) an inability to adequately distinguish immatures morphologically, and (b) insufficient information on the biological responses of different species to temperature. We will develop rapid molecular assays to distinguish blowfly species, and comprehensively chart the behavioural effects of temperature on the most forensically important blowflies. Molecular and adult morphological data will also be used to examine the evolution of the carrion-breeding blowflies.Read moreRead less
Conserving our native carnivores: the application of molecular genetics to the conservation management of quolls. Quolls, the largest native mammalian predators on mainland Australia, occupy a pivotal ecological niche. All species are declining and are threatened by a variety of interacting environmental processes. This program brings together seven wildlife agencies in a nationwide partnership for understanding and protecting quolls. We will provide new genetic data to test current populatio ....Conserving our native carnivores: the application of molecular genetics to the conservation management of quolls. Quolls, the largest native mammalian predators on mainland Australia, occupy a pivotal ecological niche. All species are declining and are threatened by a variety of interacting environmental processes. This program brings together seven wildlife agencies in a nationwide partnership for understanding and protecting quolls. We will provide new genetic data to test current population and conservation theories using four species of quolls as model taxa to inform us about past histories of populations and to measure parameters of importance to on-ground managers. Results of these projects will help guide management practices for both short- and long-term conservation of these species.Read moreRead less
The evolution of diverse interactions between Wolbachia bacteria and their invertebrate hosts: insights from a novel lineage infecting termite societies. Wolbachia intracellular bacteria are widespread in invertebrates, having evolved a remarkable range of host-interactions, from parasitic to mutualistic. I have discovered phylogenetically novel Wolbachia that infect the structural pests termites, and will investigate their host-effects and transmission dynamics. This will determine the generali ....The evolution of diverse interactions between Wolbachia bacteria and their invertebrate hosts: insights from a novel lineage infecting termite societies. Wolbachia intracellular bacteria are widespread in invertebrates, having evolved a remarkable range of host-interactions, from parasitic to mutualistic. I have discovered phylogenetically novel Wolbachia that infect the structural pests termites, and will investigate their host-effects and transmission dynamics. This will determine the generality of phenomena known from other Wolbachia, such as cytoplasmic incompatibility and horizontal transfer. The complexity of termite societies make them interesting candidates for studying how Wolbachia spread, and the results will be potentially valuable for future termite control strategies. The first comparative phylogenetic examination of diverse Wolbachia will be performed, providing new perspectives on their evolutionary history.Read moreRead less
