Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this pr ....Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this project will tackle. This proposal aims to create a technology to stabilise and deliver active gene material to target cells. The gene delivery tool developed in this project will advance biological research greatly with many potential future applications.Read moreRead less
Development of a multicomponent delivery system for oligonucleotides. Gene therapy has the ability to prevent faulty genes from causing disease, however the ability to deliver genetic material into specific cells remains a major barrier. Our research will overcome this hurdle by generating systems that are superior to existing technologies.
Gut Absorption of Constrained Peptides for Local and Systemic Targeting. Aims: This project aims to investigate how peptides are absorbed across the intestinal wall and distributed to organs and fluids in a rodent model by combining bio-analysis and pharmacokinetics with high-resolution microscopy and imaging.
Significance: This project expects to generate the most comprehensive survey to date of the pathways and mechanisms of peptide absorption, biodistribution and immune cell targeting, by ....Gut Absorption of Constrained Peptides for Local and Systemic Targeting. Aims: This project aims to investigate how peptides are absorbed across the intestinal wall and distributed to organs and fluids in a rodent model by combining bio-analysis and pharmacokinetics with high-resolution microscopy and imaging.
Significance: This project expects to generate the most comprehensive survey to date of the pathways and mechanisms of peptide absorption, biodistribution and immune cell targeting, by implementing innovative approaches.

Molecular probe development for high specificity and spatiotemporal control. This project aims at developing next-generation molecular probes with enhanced specificity and spatiotemporal control for the study of proteins and neuropeptide signalling. It addresses recognised knowledge gaps and technical bottlenecks in neuropeptide and memory research. Expected outcomes include a deeper molecular understanding of long-term memory formation and the role of neuropeptides in this process, as well as i ....Molecular probe development for high specificity and spatiotemporal control. This project aims at developing next-generation molecular probes with enhanced specificity and spatiotemporal control for the study of proteins and neuropeptide signalling. It addresses recognised knowledge gaps and technical bottlenecks in neuropeptide and memory research. Expected outcomes include a deeper molecular understanding of long-term memory formation and the role of neuropeptides in this process, as well as innovative chemistry strategies and novel molecular probes to advance fundamental research across the chemical and biological sciences.

In vitro expression of macrocyclic peptides. This project aims to develop a novel strategy for the production of polypeptides with unnatural chemical groups using a sense codon reassignment approach. Novel peptides could be used in a range of pharmaceutical applications. Peptides made of 20 natural amino acids cover only a very small fraction of the available chemical and functional space. While a peptide’s functionality can be extended with unnatural amino acids, the methods for their site-sele ....In vitro expression of macrocyclic peptides. This project aims to develop a novel strategy for the production of polypeptides with unnatural chemical groups using a sense codon reassignment approach. Novel peptides could be used in a range of pharmaceutical applications. Peptides made of 20 natural amino acids cover only a very small fraction of the available chemical and functional space. While a peptide’s functionality can be extended with unnatural amino acids, the methods for their site-selective incorporation are inefficient. The project’s strategy relies on the depletion of selected tRNAs from an in vitro protein translation system and their replacement with synthetic tRNAs, charged with unnatural amino acids. It is expected that the developed technology could be used to rapidly generate and screen highly diversified macrocyclic peptide libraries.Read moreRead less
The first integrated multimodal assay for the ultrasensitive detection of dengue contamination of blood. This project will develop the first screening test to check for dengue contamination of blood donations in Australia. This will help ensure safe, continued supply from blood donors, particularly in Queensland where dengue is on the rise.
