Predicting Biodiversity from Population Dynamics. This research aims to deepen our understanding of how changes to the environment, including those attributable to human activities, influence the ecological and evolutionary mechanisms that generate and maintain biodiversity. This understanding is of urgent importance, in light of the predicted changes in climate and habitat over the next century, because biodiversity is critical to the proper functioning of ecosystems that human societies depend ....Predicting Biodiversity from Population Dynamics. This research aims to deepen our understanding of how changes to the environment, including those attributable to human activities, influence the ecological and evolutionary mechanisms that generate and maintain biodiversity. This understanding is of urgent importance, in light of the predicted changes in climate and habitat over the next century, because biodiversity is critical to the proper functioning of ecosystems that human societies depend upon. The graduate student involved in this research will have the opportunity to receive in-depth training as part of a cross-disciplinary collaboration that combines mathematics, ecology, evolution, and paleontology.

Global Lithospheric Architecture Mapping II. The continents have been rifted, or broken up, and collided, or re-assembled, along major zones of weakness many times throughout Earth's history. Boundaries between such continental domains focus large-scale movements of fluids that can produce giant ore deposits. This study will provide new perspectives on the localisation of world-class economic deposits, the Earth resources on which society depends. Innovations in imaging the deep Earth beneath co ....Global Lithospheric Architecture Mapping II. The continents have been rifted, or broken up, and collided, or re-assembled, along major zones of weakness many times throughout Earth's history. Boundaries between such continental domains focus large-scale movements of fluids that can produce giant ore deposits. This study will provide new perspectives on the localisation of world-class economic deposits, the Earth resources on which society depends. Innovations in imaging the deep Earth beneath continents, and in numerical modelling, will maintain our high international profile in research relevant to National Priority 1.6 (Developing Deep Earth Resources). Unique 3D geological maps of regions down to 250km will make the composition of deep Earth regions newly accessible to geoscientists and all potential endusers.Read moreRead less
Mechanisms of action and expression of bioactive compounds produced by the surface associated marine bacterium Pseudoalteromonas tunicata. The marine surface-associated bacterium Pseudoalteromonas tunicata produces a number of bioactive metabolites that inhibit the colonisation and growth of common fouling organisms such as bacteria, fungi, algae and invertebrate larvae.

The marine surface-associated bacterium Pseudoalteromonas tunicata produces a number of bioactive metabolites that inhibit the colonisation and growth of common fouling organisms such as bacteria, fungi, algae and invertebrate larvae. The antibacterial and antifungal compounds represent novel metabolites active against a remarkable range of both medically and agriculturally important bacteria and fungi. This project aims to explore the identity, mode of action and regulation of expression of these compounds. This research proposal addresses several significant biological concepts and will lead to the development of novel environmentally friendly antifouling and antimicrobial technologies.Read moreRead less
Chemical Defenses Against Microbial Colonisation of Living Marine Surfaces. Microorganisms have a major impact on all ecosystems. Many of these effects are due to the formation of biofilms - cell clusters and their slime matrix - on living and non-living surfaces. Biofilm formation is often regulated by chemical signals. The aim of this project is to understand how naturally produced chemical signals mediate the formation of biofilms on surfaces of marine macroalgae (seaweeds) at both the eco ....Chemical Defenses Against Microbial Colonisation of Living Marine Surfaces. Microorganisms have a major impact on all ecosystems. Many of these effects are due to the formation of biofilms - cell clusters and their slime matrix - on living and non-living surfaces. Biofilm formation is often regulated by chemical signals. The aim of this project is to understand how naturally produced chemical signals mediate the formation of biofilms on surfaces of marine macroalgae (seaweeds) at both the ecological and molecular levels. By understanding colonisation of natural living surfaces, this project will lead directly to significant advances in control of microorganisms in a variety of applied areas (water treatment, biomaterials, antifouling).Read moreRead less
The role of phospholipids in the biogenesis of lipid droplets. The general aim is to elucidate the fundamental molecular mechanisms that govern the biogenesis/formation of the lipid droplets. Lipid droplets store sterol esters and/or triacylglycerols, two major storage lipids that play key roles in cellular and whole body lipid metabolism. Lipid droplets are also the core components of plant oil and biodiesel. Little is known about how lipid droplets are generated. The proposed work will examine ....The role of phospholipids in the biogenesis of lipid droplets. The general aim is to elucidate the fundamental molecular mechanisms that govern the biogenesis/formation of the lipid droplets. Lipid droplets store sterol esters and/or triacylglycerols, two major storage lipids that play key roles in cellular and whole body lipid metabolism. Lipid droplets are also the core components of plant oil and biodiesel. Little is known about how lipid droplets are generated. The proposed work will examine the synthesis of certain lipid intermediates such as phosphatidic acid, and their impact on the biogenesis of lipid droplets from the endoplasmic reticulum. Such fundamental new knowledge on how cells store neutral lipids will provide new strategies for enhancing plant oil and biodiesel production. Read moreRead less

This project will create new mathematical algorithms to flexibly manage open pit mining projects. The development of strategic plans for mining operations is a highly complex task, based on incomplete geological information and uncertain future commodity demand. The smart mathematics we create will allow Australia to capitalise on upturns in international demand, while limiting unavoidable negative outcomes, by flexibly adjusting the mining operation to prevailing geological and economic conditions. Australia's mineral exports are worth over $50b annually to the Australian economy. Our techniques will better manage Australia's mining projects and capture new, emerging markets, significantly impacting on Australia's balance of trade.Read moreRead less
Ecological consequences of hydrodynamic disturbances. The Great Barrier Reef is synonymous with Australia to many people worldwide.
