Directed evolution of ancestral bacterial flagellar motors. This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. .

This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. . This project will combine ancestral reconstruction of ancient motor components with protein engineering to understand how the different ion channels that power the BFM in different species are selective for different positive ions. It will inspire and inform future manufacturing in bionanotechnology.Read moreRead less

The project will will enable Australia to take the lead in the global analysis of oligotrophy, highlighting the reputation Australian scientists have in scientific programs of global significance. As Australia is surrounded by some of the most oligotrophic waters in the world, we have access to an enormous natural resource suitable for the isolation of oligotrophs. Realising the potential of oligotrophs may therefore provide an invaluable source of compounds, enzymes and molecules for biotechnology and industry. Understanding microbial oligotrophy will also ensure we protect our $50 billion dollar tourism industry by remaining abreast of factors which influence the marine environment and directly impact on all coastal activities.Read moreRead less
Control of Wolbachia replication: maintaining a stable symbiosis. This project will use a comparative genomics approach to better understand how Wolbachia infections of insects are able to maintain themselves in insects without causing pathology. The results will allow us to better understand a distinguishing characteristic of an intracellular symbiont, namely replication control. The results also have the potential to lead to new approaches to insect pest control through a better understanding ....Control of Wolbachia replication: maintaining a stable symbiosis.

A comparative genomics approach to understanding host-endosymbiont interactions. Australia's unique ecosystems are vulnerable to invasion by exotic pests that threaten agriculture and human health. The bacterial symbiont Wolbachia is found in many major pests of agricultural and medical importance. Our results will give insights into how Wolbachia spreads into host populations and improve its use as a tool to impair insect transmission of disease, e.g. as an agent to carry genes into an insect p ....A comparative genomics approach to understanding host-endosymbiont interactions. Australia's unique ecosystems are vulnerable to invasion by exotic pests that threaten agriculture and human health. The bacterial symbiont Wolbachia is found in many major pests of agricultural and medical importance. Our results will give insights into how Wolbachia spreads into host populations and improve its use as a tool to impair insect transmission of disease, e.g. as an agent to carry genes into an insect population that limit disease transmission. Our results will also make fundamental contributions to understanding host-parasite evolution, host-parasite communication, and insect developmental processes, and will be of interest to a large international community of researchers in this field.

Rerunning the evolution of an ancient bacterial propeller. This project aims to measure how the propeller which drives bacterial swimming originated and then evolved. This project expects to generate new knowledge in molecular evolution using interdisciplinary techniques in synthetic biology and biophysics to resurrect ancient proteins and test how they can be directed to evolve in a contemporary host. Expected outcomes include the development of new types of flagellar motor for applied uses in ....Rerunning the evolution of an ancient bacterial propeller. This project aims to measure how the propeller which drives bacterial swimming originated and then evolved. This project expects to generate new knowledge in molecular evolution using interdisciplinary techniques in synthetic biology and biophysics to resurrect ancient proteins and test how they can be directed to evolve in a contemporary host. Expected outcomes include the development of new types of flagellar motor for applied uses in synbio and microfluidics, and new methods to resurrect ancient proteins and evolve their function for purpose. This should provide significant benefits by delivering a de novo molecular motor for custom applications and galvanise public interest in how this iconic molecular complex originated and evolved.Read moreRead less

Transcription factors are “undruggable” targets playing a principal role driving cancer. This project will create novel therapeutic strategies to inhibit transcription factors and other elusive targets differentially expressed in diseased cells, without affecting normal tissue. It proposes to construct engineered proteins able to bind and modify specific key genes deregulated in cancer, to correct their expression and stably reprogram the phenotype of the tumour cell in a normal-like state. It outlines the engineering of novel synthetic agents to block specific protein-protein interactions in cancer cells and to induce potent tumour cell death. This work will generate novel and selective therapeutics to treat un-curable forms of tumours.Read moreRead less
Chromatin barriers in Plasmodium falciparum gene regulation. Malaria is a major world disease that kills around 2 million people annually. The genome of the causative agent has now been completely sequenced, but we still know very little of how and why some genes are activated while their neighbours are turned off. I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites.

I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites. A better understanding of gene regulation in malaria parasites will help us to better combat the tricks utilised by this and other organisms to elude our immune systems.Read moreRead less

Investigating the Genetic Basis of Human Intrinsic Capacity. Intrinsic capacity is a new concept introduced by experts at the World Health Organisation to promote healthy ageing. It is defined as the composite of an individual’s physical and mental capacities, based on measures of five criteria; cognitive, sensory, locomotor, vitality and psychological. It is a genetically predetermined trait, but is influenced by a range of environmental stimuli. Applying a cutting-edge genetic methodology on b ....Investigating the Genetic Basis of Human Intrinsic Capacity. Intrinsic capacity is a new concept introduced by experts at the World Health Organisation to promote healthy ageing. It is defined as the composite of an individual’s physical and mental capacities, based on measures of five criteria; cognitive, sensory, locomotor, vitality and psychological. It is a genetically predetermined trait, but is influenced by a range of environmental stimuli. Applying a cutting-edge genetic methodology on big biobank datasets, this project aims to examine the role of genetics and the environment to explain the variability of intrinsic capacity between individuals. Understanding the biological basis of intrinsic capacity has major implications for scientific research in healthy ageing and mental wellbeing.Read moreRead less
