Laser emission at the limit of glass transparency using nanocrystal doping . We will create a new composite glass providing strong fluorescence which fully exploits the high transmission of glass in the mid-infrared. When combined with emerging rare earth ion transitions and precise excitation processes, this project will help solve an important problem in optics; that the overall efficiency and power produced from deep mid-infrared light sources is not sufficient for all industries.

We will create a new composite glass providing strong fluorescence which fully exploits the high transmission of glass in the mid-infrared. When combined with emerging rare earth ion transitions and precise excitation processes, this project will help solve an important problem in optics; that the overall efficiency and power produced from deep mid-infrared light sources is not sufficient for all industries. The primary outcome will be a series of robust fibre-based gain modules suitable for high power and very short optical pulses in the mid-infrared. These light sources will beneficially impact medicine, defence, sensing and manufacturing providing excellent opportunities for increasing Australian productivity and global competitiveness.

Nanoscale silicon field-effect transistor diagnostic technology. This project aims to overcome barriers to the implementation of silicon field-effect transistor biosensors. It will investigate the biosensors’ physical and structural properties. This knowledge, combined with technological and conceptual advances, could foster the development of an advanced and translational point-of-care diagnostic technology to rapidly and sensitively detect malignant tissues.

Substrate-integrated wearable antennas for unobtrusive activity monitoring. This project aims to develop a novel class of wearable textile antennas that can form robust connections with miniature battery-less motion sensors for non-invasive activity monitoring of older people. In contrast to bulky body worn sensors that must be strapped on, it is anticipated that the garment-integrated textile antennas patterned through computerised embroidery will lead to low-cost, low-profile, and flexible ant ....Substrate-integrated wearable antennas for unobtrusive activity monitoring. This project aims to develop a novel class of wearable textile antennas that can form robust connections with miniature battery-less motion sensors for non-invasive activity monitoring of older people. In contrast to bulky body worn sensors that must be strapped on, it is anticipated that the garment-integrated textile antennas patterned through computerised embroidery will lead to low-cost, low-profile, and flexible antennas that are truly wearable with exceptional performance and scalable manufacturing techniques. The outcomes from the project are expected to underpin innovative applications, such as aged care, providing a means for caregivers to automatically monitor health and physical activity and intervene as required. Such applications would support ageing Australians to live with greater independence and safety.Read moreRead less
Snake fangs: insights into evolution, palaeoclimate and biodesign . This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniqu ....Snake fangs: insights into evolution, palaeoclimate and biodesign . This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniques. This should greatly improve understanding of the evolution of venom fangs in all snakes. Other benefits include a large 3D reference database allowing identification of fossil fangs, with applications for studies of past climates, and a characterisation of fang biomechanics, relevant to biodesign and biomimicry.Read moreRead less
Dynamic terahertz superlenses for sub-wavelength sensing and imaging. We propose to develop a 'dynamic terahertz superlens' that will dramatically enhance the performance of existing T-ray imaging systems used for biosensing of cells, DNA and proteins. The science of the superlens is remarkable in that it enables image resolution shorter than the wavelength.
Functional characterisation of poly-histidine triad proteins. This project aims to understand the role and function of a novel family of surface proteins produced by Streptococci. These so-called polyhistidine triad proteins are known to contribute to capacity to cause disease in animals and humans, but we need to know how they work, as they may be excellent targets for novel drugs or vaccines.
Novel perspectives on the function of AB5 toxin B subunits in pathogenic bacterial. AB5 toxins are produced by bacteria that cause important diseases in humans and livestock. This project tests the hypothesis that the components of the toxins responsible for binding to host cells and tissues also directly contribute to cellular damage, thereby providing a better understanding of how AB5 toxin-producing bacteria cause disease.
Combating fungal biofilm growth on surfaces. This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces. Advancing mechanistic understanding of how physico-chemical properties of materials surfaces influence fungal attachment will enable rational development and optimisation of coating chemistries and struc ....Combating fungal biofilm growth on surfaces. This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces. Advancing mechanistic understanding of how physico-chemical properties of materials surfaces influence fungal attachment will enable rational development and optimisation of coating chemistries and structures. Tethered antifungal compounds will be added to polymer surfaces by controlled polymerisation methods to provide active deterrence; factors such as conformational flexibility will be studied to optimise coatings, which may will prevent life-threatening infections and reduce healthcare costs.Read moreRead less
Bacterial poly-histidine triad proteins. The poly-histidine triad (Pht) proteins are a poorly characterised family of surface proteins expressed by the genus Streptococcus and other Gram-positive genera. Recent studies suggest an important role for Pht proteins in survival of these bacteria in low zinc (Zn) environments. The project hypothesis is that Pht proteins specifically recruit Zn from the extracellular environment and somehow make it available to ATP binding cassette (ABC) transport syst ....Bacterial poly-histidine triad proteins. The poly-histidine triad (Pht) proteins are a poorly characterised family of surface proteins expressed by the genus Streptococcus and other Gram-positive genera. Recent studies suggest an important role for Pht proteins in survival of these bacteria in low zinc (Zn) environments. The project hypothesis is that Pht proteins specifically recruit Zn from the extracellular environment and somehow make it available to ATP binding cassette (ABC) transport systems located in the bacterial plasma membrane, beneath the cell wall, facilitating Zn uptake by the bacterium. The aim of this project is to conduct comprehensive molecular characterization of the interactions between Pht proteins, Zn and ABC transporters, and the role of the histidine triad motifs in these interactions.Read moreRead less

I will continue the development of CANGAROO-III and establish links with the other collaborations in this field, in particular H.E.S.S., also in the southern hemisphere. Studies with CANGAROO-III of high energy gamma-ray sources such as supernova remnants and active galaxies will finally reveal the type of particles that are accelerated in such violent regions of our universe. The development of future ground-based gamma-ray detectors beyond CANGAROO-III is also a project aim, and will expand the energy coverage of gamma-ray detectors into uncharted territory.Read moreRead less
