Summary
Obesity and Type 2 diabetes (T2D) increase risk of cardiovascular disease (CVD), a leading cause of death in Australia. New drugs are required to reduce the health risks and financial burden of these diseases. Targeting hormone receptors to reduce fat storage in liver and skeletal muscle in obesity may improve insulin sensitivity and reduce blood sugar levels and therefore reduce CVD risk. This research will study how these receptors function in order to develop new drugs to reduce CVD risk.

Molecular insights into bacterial metal ion homeostasis and toxicity. This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity.

This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without accumulating a toxic excess (metal homeostasis) is poorly understood. Discovering the roles of metal ions in bacterial cells will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environments.Read moreRead less

Plasmonic nanoparticles for probing and perturbing the spatial organisation of membrane proteins. Receptors on the surface of cells provide vital functions and represent a large fraction of drug targets. It is believed that the spatial organisation of receptors can effect their function. This project will test this hypothesis by combining nanotechnology with biophysics to watch and manipulate the spatial organisation of receptors.
Tuning Molecular Translocaton by Close-Field Electroporation. This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies.

It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed to establish the properties of the electric fields around cells and cell membrane interactions with these fields that enable molecular translocation. This fundamental science could have broad implications in the domains of drug delivery, gene therapy and neural stimulation.Read moreRead less

The metal ion manganese is essential to all forms of life. This project aims to investigate how this poorly abundant cation is selectively acquired from the chemical complexity of the environment for import into cells by using state-of-the-art biochemical and microbiological techniques. This project expects to define the fundamental basis for how bacterial, archaeal and eukaryotic plastid cation-selective importers can discriminate manganese from chemical similar cations to achieve selective uptake. The expected outcomes of this work will be an understanding of the fundamental basis for selective metal import in biological systems. This should provide benefits for industry through synthetic biological applications of this knowledge. Read moreRead less
