Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be ca ....Erosion processes in soils across scales. This project aims to develop a monitoring tool for predicting the evolution of internal erosion in dams based on innovative electromagnetic observation methods. Internal erosion is an insidious process occurring in the obscurity of the soil’s pore system until its consequences become visible and threaten the stability of the dams. These water retaining structures are vital for the future water and energy supply for our society and their failure can be catastrophic. By establishing an improved understanding of internal erosion as a sequence of processes on various scales, from the onset of erosion until the failure of the structure, this project will place Australia at the forefront of dam safety assessment.Read moreRead less

Expansive soils, highly sensitive to the environment, undergo dramatic strength and volume changes. This project aims to advance our understanding of expansive soils under different temperatures, hydraulic conditions, mechanical loads, and aqueous salinities. The project expects to use a combination of multidisciplinary knowledge, multiscale experiments and numerical simulations. The outcomes are a new multiscale model and advanced analysis/design tool for evaluating the performance of expansive soils under different conditions. The outcomes should provide the efficient way to mitigate the significant damage caused to infrastructure by expansive soils and facilitate the application of expansive soil products in waste disposal systems.Read moreRead less
Direct geothermal energy: harnessing an emerging technology. To mitigate the impacts of climate change, the demand for renewable energy technologies with low greenhouse gas (GHG) emissions is rapidly becoming a global priority. Direct geothermal systems use shallow ground as a heat source and sink for heating and cooling buildings, using ground heat exchangers (GHEs) and heat pumps. Substituting common heating and cooling systems with geothermal ones can reduce energy consumption by up to 75 per ....Direct geothermal energy: harnessing an emerging technology. To mitigate the impacts of climate change, the demand for renewable energy technologies with low greenhouse gas (GHG) emissions is rapidly becoming a global priority. Direct geothermal systems use shallow ground as a heat source and sink for heating and cooling buildings, using ground heat exchangers (GHEs) and heat pumps. Substituting common heating and cooling systems with geothermal ones can reduce energy consumption by up to 75 per cent and thus greenhouse gas emissions, since 91 per cent of electricity comes from fossil fuels in Australia. This project aims to develop new full scale physical and numerical models which will allow studying the effects of GHE configuration and intermittent use on efficiency and which will lead towards improving the poor and scarce existing design techniques.Read moreRead less
Designing functional biomaterials with superior cellular interactions. This proposal aims to make a new class of biomaterials that direct important cellular functions such as adhesion, proliferation, and differentiation. This will be achieved by developing materials that leverage a previously unexplored mechanism that was recently identified in my lab: the co-engagement of integrin and syndecan-4 cell receptors.

Novel cement-graphene oxide composite: understanding its composite structure via nano-mechanics based modelling and experimental tests. A high performance cement composite will be developed to reduce the usage of cement, and steel reinforcement, thus decrease carbon dioxide emissions, reduce labour costs, and promote sustainability. Modern modelling techniques will advance the knowledge in cement and concrete field and maintain the leading position of Australia.
Anchoring the next generation of offshore floating infrastructure. This project aims to advance the fundamental scientific understanding of embedded anchor behaviour and to develop engineering solutions to secure the next generation of floating platforms, wind turbines and submerged tunnels. This is significant because limited understanding of anchors under long-term sustained and cyclic loading, and in how wave-chain-anchor systems behave, is hindering confident deployment in deep water and har ....Anchoring the next generation of offshore floating infrastructure. This project aims to advance the fundamental scientific understanding of embedded anchor behaviour and to develop engineering solutions to secure the next generation of floating platforms, wind turbines and submerged tunnels. This is significant because limited understanding of anchors under long-term sustained and cyclic loading, and in how wave-chain-anchor systems behave, is hindering confident deployment in deep water and harsh conditions. This project will address this challenge by combining precise observations from sophisticated physical and numerical experiments into an analysis framework that integrates system response. Outcomes will include numerical software, analytical tools and design charts for engineers to use in design.Read moreRead less

This project aims to allow the use of low-cost, low-intensity light sources, such as light-emitting diodes and discharge lamps, to generate nonlinear optical signals in photonic devices. Nonlinear optical effects are vital for telecommunication and signal processing technologies and are presently possible only when the light is produced by a high-power laser. The expected outcome of this project is a theoretical and experimental framework that would underpin the development of a new nonlinear photonic technology that does not require lasers, representing a paradigm shift in how photonic devices are designed. This should benefit sensing, telecommunications and defence by cheaper and more efficient transmission of information via media such as the National Broadband Network.Read moreRead less

This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.Read moreRead less
