Fundamental study of fracture-controlled compensation grouting for ground movement. This project aims to investigate the fundamentals of fracture-controlled compensation grouting in various types of soil, so as to optimise the compensation efficiency and to minimise the risk of collapse of nearby structures. This will result in the minimisation of ground movements induced by underground excavations, which pose a major threat to existing infrastructure and communities worldwide.

This project aims to develop adaptive structural systems for high-performance buildings. A new theoretical platform will be instrumental in the development of building technologies such as adaptive shading and ventilation components. In a reversal of the conventional design avoidance of structural phenomena such as lateral and flexural-torsional buckling, these phenomena will be exploited to achieve functional forms for shading components. Thin-metal ventilation ducts will be embedded within structural components to produce optimised ventilation strategies and to increase thermal mass, while accounting for their structural contribution.Read moreRead less
Modelling and simulation of complex granular flows. Granular flows are of crucial importance in a wide range of problems related to civil infrastructure. These include landslides and similar catastrophic events, often leading to loss of life and property. The project aims to develop new methods for accurate prediction of such events thus allowing for the formulation of efficient mitigation strategies.

Inventiveness and the progress of product innovation. Quantitative models of inventiveness will be used to forecast the potential rate of improvement of a technology and to re-design products to improve more rapidly and steadily. By focusing on innovation in products and technologies in energy conversion, this research can guide development funding for low-carbon energy generation.
Electro-triggered solidification of supercooled fusible alloys. Stiffness is typically considered a static property of a material. Traditionally, once the stiffness is specified, it is not expected to change during operation. This project aims to turn a problem (i.e., supercooling) into an opportunity for creating fusible alloy composites with electroprogrammable stiffness that can outperform state-of-the-art materials by offering all desirable properties. Expected outcomes are the rapid, contin ....Electro-triggered solidification of supercooled fusible alloys. Stiffness is typically considered a static property of a material. Traditionally, once the stiffness is specified, it is not expected to change during operation. This project aims to turn a problem (i.e., supercooling) into an opportunity for creating fusible alloy composites with electroprogrammable stiffness that can outperform state-of-the-art materials by offering all desirable properties. Expected outcomes are the rapid, continuous, large, and reversible change in stiffness of the composite through electrical control. This project will provide significant benefits by enabling an increasing number of emerging applications in areas such as robotics, manufacturing, and consumer wearables that require materials with tuneable stiffness.Read moreRead less
Integrated Piezoelectric Microsystems for Actuation and Sensing. Piezoelectric transducers provide the highest positioning accuracy of any known actuator and the highest dynamic force resolution of any known sensor. However, these capabilities are limited to macro scale applications since piezoelectric materials are not compatible with integrated circuit (IC) or Micro-Electro-Mechanical Systems fabrication processes. This project aims to extend the use of piezoelectric materials to the meso- and ....Integrated Piezoelectric Microsystems for Actuation and Sensing. Piezoelectric transducers provide the highest positioning accuracy of any known actuator and the highest dynamic force resolution of any known sensor. However, these capabilities are limited to macro scale applications since piezoelectric materials are not compatible with integrated circuit (IC) or Micro-Electro-Mechanical Systems fabrication processes. This project aims to extend the use of piezoelectric materials to the meso- and micro-scale by fabricating miniature piezoelectric positioning and sensor systems. These devices will include six-axis nano-positioners and ultra-high resolution accelerometers and gyroscopes. This technology will create a new market for devices that are lower cost than macro-scale systems but provide higher performance than silicon based microsystems.Read moreRead less
Real-time friction sensing, feedback and control for dexterous prosthetic and robotic manipulation. Prosthetic and robotic hands demonstrate poor dexterity during object manipulation, often dropping objects. Humans rarely allow objects to slip because we can sense when an object is slippery and adjust our grip. Exceptionally little research has been directed at replicating this ability to sense friction. This project aims to enable artificial hands to estimate frictional properties while graspin ....Real-time friction sensing, feedback and control for dexterous prosthetic and robotic manipulation. Prosthetic and robotic hands demonstrate poor dexterity during object manipulation, often dropping objects. Humans rarely allow objects to slip because we can sense when an object is slippery and adjust our grip. Exceptionally little research has been directed at replicating this ability to sense friction. This project aims to enable artificial hands to estimate frictional properties while grasping an object. Non-invasive methods to feed back this frictional information to an amputee will also be investigated. Finally, the friction-sensing system will be used to improve robotic gripper control. The outcomes of this research will significantly advance the fields of prosthetics, telesurgery, and service and manufacturing robotics.Read moreRead less

The electrical power industry in Australia is undergoing a massive revolution to an intelligent, low-carbon and sustainable smart grid environment. However, due to the heavy reliance on cyber infrastructure and the intermittence of renewables, smart grid will inevitably introduce new security issues, for example, cyber security. This project is to investigate emerging security issues together in a comprehensive framework where quantitative models and analysis methods will be explored for smart grid cascading failure analyses. Then innovative three-stage reinforcement strategies (three lines of defence) will be developed to enhance the resilience of smart grid against natural disasters and intentional attacks, and potential large blackouts.
