Evolutionary origins of sexual parasitism in an Australian freshwater fish. Carp gudgeons are the most abundant, widespread and biodiverse freshwater fishes in southeastern Australia. The unacknowledged presence of many cryptic species and sexually-parasitic lineages severely taints all research on this cornerstone group.

Carp gudgeons are the most abundant, widespread and biodiverse freshwater fishes in southeastern Australia. The unacknowledged presence of many cryptic species and sexually-parasitic lineages severely taints all research on this cornerstone group. This project aims to provide unrivalled evolutionary, genomic, and taxonomic insights into this new instance of vertebrate sexual parasitism, which offers a unique mix of research advantages not displayed by any other sexual/unisexual complex. The knowledge gained could impact many research fields, including evolutionary theory addressing the unexplainable prevalence of sex, native fish ecology, and environmental monitoring of the Murray-Darling Basin, an ecosystem of world significance.Read moreRead less

This project aims to investigate molecular mechanisms involved in the formation of undesired biological deposits on synthetic materials and thereby help establish the scientific basis for the rational design of materials with improved compatibility with biological fluids and the engineering of a new generation of biomedical implant devices and bio-diagnostic devices. It is well known that proteins accumulate on synthetic solid surfaces. This project proposes to investigate whether lipids and lipoproteins also play key roles in the initiation of biological adsorption processes. Combined with the study of the interfacial forces responsible, this information will guide the design of preventative strategies.Read moreRead less

Australia's scientific competitiveness will be strengthened in the fields of nano-encapsulation and colloidal delivery.Read moreRead less
Origins and distributions of intraplate earthquakes. This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data.

This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to improve models of future seismic hazard in Australia and globally. This will lead to improved predictions of future earthquake impacts in urban and natural environments and development of new paleoseismic techniques.Read moreRead less

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.

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

A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each ....A new angle on the coalescence of drops.

This project aims to develop and implement a systematic approach, both analytic and computational, to extract compact, accurate, system level models of complex physical and engineering systems. The wide ranging methodology is to construct computationally efficient "wrappers" around fine scale, microscopic, detailed descriptions of dynamical systems (particle or molecular simulation, or partial differential equations or lattice equations). Comprehensively accounting for multiscale interactions between subgrid processes among macroscale variations ensures stability and accuracy. Based on dynamical systems theory and analysis, this approach is expected to empower systematic analysis and understanding for optimal macroscopic simulation for forthcoming exascale computing.Read moreRead less
