This project aims to develop a computational approach to collisions involving molecular targets with electrons, positrons and heavy particles. Recently, the approach to atomic collisions, the Convergent Close Coupling (CCC) method, has been extended and verified for positron, electron, and heavy particle collisions with the simplest molecular systems (molecular hydrogen and its ion). This project now aims to extend the CCC method to study collisions with more complex molecules. Expected benefits include more accurate data for diagnostic tools such as Positron Emission Tomography, and potential advances in particle-based cancer therapy.Read moreRead less
Low-energy electron transport in soft-condensed biological matter. To obtain optimal accuracy and selectivity of ionising radiation based technologies requires an understanding and quantification of the underpinning fundamental physical processes. This project will focus on developing accurate theoretical models of low-energy electron transport in biological matter which account for new physical mechanisms.
Quantum collision theory for astrophysics, fusion energy and hadron therapy. The project intends to investigate collision processes involving charged particles interacting with complex atoms and molecules. Although the theory of electron, positron and ion collisions with simple atoms and molecules has advanced in recent years, the corresponding computational modelling is difficult due to the mix of the countably and uncountably infinite spectrum of the target, the long-range Coulomb potential, a ....Quantum collision theory for astrophysics, fusion energy and hadron therapy. The project intends to investigate collision processes involving charged particles interacting with complex atoms and molecules. Although the theory of electron, positron and ion collisions with simple atoms and molecules has advanced in recent years, the corresponding computational modelling is difficult due to the mix of the countably and uncountably infinite spectrum of the target, the long-range Coulomb potential, and the multicentre nature of the target and the rearrangement processes. These difficulties could be overcome using a convergent close-coupling method. This project plans to apply the method to complex quantum collision systems in diverse applications of current interest such as fusion energy, lighting, astrophysics, and cancer imaging and therapy.Read moreRead less
Metaphotonics and metasurfaces for disruptive sensing technologies. This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures.

This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures. Resonant metasurfaces are arrays of engineered dielectric nanoparticles with extraordinary characteristics, and they would allow to overcome current limitations of chiral sensing analytical tools. Detecting chiral molecules in low concentrations is crucially important to many fields of biology, chemistry, and pharmacy, as well as to the food and cosmetics industries, constituting a market of tens of billions of dollars.Read moreRead less
Extreme wave events on the water surface. Giant waves observed in the ocean present a catastrophic threat to ships and offshore structures. Rogue waves in optical fibres, on the other hand, may help developing powerful light sources for long-distance telecommunications. This study of capillary rogue waves on the water surface will help to predict and control the probability of extreme waves.

This project aims to develop a new class of synthetic thin films, with unique optical signatures as strong anti-counterfeiting features for future generations of Australian banknotes. The project expects to produce novel, ultra-thin films patterned on the nanoscale that produce vivid, easily recognisable optical effects building on recent advances in nanophotonic optical design and scalable nanofabrication strategies.

The project expects to produce novel, ultra-thin films patterned on the nanoscale that produce vivid, easily recognisable optical effects building on recent advances in nanophotonic optical design and scalable nanofabrication strategies. The development of a range of optical security features in Australia will ensure long-term confidence in our currency. An outcome of the project could be the commercialisation of new types of anti-counterfeiting features for use in Australia and overseas.Read moreRead less
Modelling and characterisation of radiation beams used in radiotherapy. The purpose of this project is to use computer modelling of radiation fields in radiotherapy to investigate and improve their precision. It is expected that this will result in improved outcomes and fewer side-effects for radiotherapy patients.

Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows.

This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use laboratory models and new measurement techniques to study and quantify the impact of biofilms on turbulent transport. Understanding these effects is important in a time of climate change and this knowledge may also help address environmental issues related to spreading of pollutants and flow control at the ocean surface.Read moreRead less

This project aims to transform the understanding of the structure and function of the brain as a complex physical system. It aims to reveal and unify new aspects of information processing, transitions in conscious state, and nonlinear brain interactions by translating and applying concepts and methods from physics and mathematics. It will treat brain structure and dynamics together to address emergent phenomena like waves and patterns on multiple scales, treating waves as equal participants alongside neurons. Innovative predictions of brain phenomena will aim to be verified against data and used to understand brain networks, dynamics, and the physical phenomena underlying information processing and consciousness.Read moreRead less
