Chronic inflammation underlies common and debilitating diseases and causes pain by unknown mechanisms. There is an urgent need to gain a deeper understanding of the mechanisms of chronic pain, which will allow the development of improved therapies with fewer side-effects. Our research program investigates the mechanisms of pain that are associated with inflammatory bowel disease and irritable bowel syndrome, with the goal of developing more effective and selective therapies.

Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.
Nanoscale characterisation of the dynamics of artificial lipid membranes - model systems for drug binding studies. This project will see the development of artificial membranes replicating the physiological behaviour of cell membranes providing a novel platform for in vitro drug evaluation clearing the way for the development of effective new therapies with fewer side effects.
New mechanisms regulating the biogenesis of extracellular vesicles. Extracellular vesicles are small packages that contain active components derived from the cell of origin. These vesicles, released by most cell types, are critical for communication between cells. However, the processes of their formation and release remain poorly understood. This project aims to explore how ubiquitination, a type of protein modification system, controls the production of extracellular vesicles. Using a strong c ....New mechanisms regulating the biogenesis of extracellular vesicles. Extracellular vesicles are small packages that contain active components derived from the cell of origin. These vesicles, released by most cell types, are critical for communication between cells. However, the processes of their formation and release remain poorly understood. This project aims to explore how ubiquitination, a type of protein modification system, controls the production of extracellular vesicles. Using a strong collaborative team and highly innovative approaches, the project will generate new knowledge to inform how cells communicate. Expected outcomes include knowledge of broad significance to cell biology, that can be leveraged to develop extracellular vesicles as tools for various biotechnology applications in the future.Read moreRead less
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. 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 ....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. 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
New molecular tools to study the mechanisms of bacterial metal homeostasis. This project aims to provide new insight into how metal ion uptake is regulated. It will precisely measure the cellular concentrations of metal ions, reveal the roles of metal ions in essential cellular processes, and identify the molecular targets of metal toxicity. Metal ions are essential to all forms of life and are used by up to half of all proteins to facilitate cellular chemical processes. The intended outcome of ....New molecular tools to study the mechanisms of bacterial metal homeostasis. This project aims to provide new insight into how metal ion uptake is regulated. It will precisely measure the cellular concentrations of metal ions, reveal the roles of metal ions in essential cellular processes, and identify the molecular targets of metal toxicity. Metal ions are essential to all forms of life and are used by up to half of all proteins to facilitate cellular chemical processes. The intended outcome of the research is to provide new fundamental knowledge of the roles of metal ions in bacterial cells; knowledge that 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
Exploring the immunomodulatory potential of Natural Killer T cells. Natural Killer T cells (NKT cells) are an innate-like population of T cells that recognise a range of lipid based antigens when bound to the antigen-presenting molecule, CD1d. Once activated, NKT cells rapidly secrete a variety of cytokines. This project, in partnership with Vaxine Pty Ltd, aims to gain a basic understanding of NKT recognition of lipids and NKT cell activation by lipids. The project aims to use a combination of ....Exploring the immunomodulatory potential of Natural Killer T cells.
