The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Summary
Developing the toolbox of compounds that target acid-sensing proteins. This project aims to examine the interaction between acid-sensing proteins and their modulatory compounds. Animals, including humans, must sense changes in environmental acidity to successfully interact with the surrounding world. Expected outcomes of the project include a better understanding of which regions of these proteins detect acidity, and to develop new compounds that modulate the proteins’ function. This would advan ....Developing the toolbox of compounds that target acid-sensing proteins. This project aims to examine the interaction between acid-sensing proteins and their modulatory compounds. Animals, including humans, must sense changes in environmental acidity to successfully interact with the surrounding world. Expected outcomes of the project include a better understanding of which regions of these proteins detect acidity, and to develop new compounds that modulate the proteins’ function. This would advance our fundamental knowledge in the physiological process of acid sensing. This expects to provide significant benefits, by aiding the potential development of agrochemicals and pain-relieving medications that regulate acid-sensing protein function, resulting in economic benefit to Australia via these new products.

Understanding and controlling neuropeptide GPCR-transducer coupling. G protein-coupled receptors (GPCRs) are physiologically essential, yet the spatiotemporal complexity of receptor function has limited our understanding of their function and success in drug development. Using a multi-disciplinary approach integrating GPCR signalling, trafficking and drug delivery, this research program aims to understand, and control, the molecular mechanisms that enable a single receptor to respond to differen ....Understanding and controlling neuropeptide GPCR-transducer coupling. G protein-coupled receptors (GPCRs) are physiologically essential, yet the spatiotemporal complexity of receptor function has limited our understanding of their function and success in drug development. Using a multi-disciplinary approach integrating GPCR signalling, trafficking and drug delivery, this research program aims to understand, and control, the molecular mechanisms that enable a single receptor to respond to different ligands to promote unique cellular processes. The anticipated outcomes include an enhanced capacity for understanding fundamental biology, and stronger national and international collaborations. It will provide significant benefits including expanded basic knowledge and advancement of drug delivery technology.Read moreRead less

Summary
Molecular insights into the allosteric regulation of opioid receptors. Allosteric regulation is the biological process by which molecules bind to proteins someplace other than their active site, regulating their activity. Proteins on the cell surface called membrane receptors can be allosterically regulated to fine-tune the response of cells to the environment. This project aims to investigate how small molecules regulate receptor activity at a molecular level, using opioid receptors as an exemp ....Molecular insights into the allosteric regulation of opioid receptors. Allosteric regulation is the biological process by which molecules bind to proteins someplace other than their active site, regulating their activity. Proteins on the cell surface called membrane receptors can be allosterically regulated to fine-tune the response of cells to the environment. This project aims to investigate how small molecules regulate receptor activity at a molecular level, using opioid receptors as an exemplar system. I will use an interdisciplinary approach that combines structural biology, medicinal chemistry, analytical pharmacology, and cell biology. The knowledge gained from these studies will advance fundamental understanding of receptor function and can lay the foundation for future drug discovery efforts.Read moreRead less
Structure and dynamics of class B1 G protein coupled receptors . Cells within our body require cell surface proteins (receptors) to convert extracellular stimuli into an appropriate biological response. G protein-coupled receptors are the largest group of cell surface receptors. This project focuses on a subset of these receptors that have diverse and important functions in the central nervous system and the periphery, however there are many unanswered questions regarding the structure of these ....Structure and dynamics of class B1 G protein coupled receptors . Cells within our body require cell surface proteins (receptors) to convert extracellular stimuli into an appropriate biological response. G protein-coupled receptors are the largest group of cell surface receptors. This project focuses on a subset of these receptors that have diverse and important functions in the central nervous system and the periphery, however there are many unanswered questions regarding the structure of these proteins, and how they regulate cellular signalling. The primary outcomes of this project will provide detailed mechanistic insights on how receptors bind their stimuli and how this results in in their activation to mediate fundamental signalling that is important for all living organisms.Read moreRead less
The physiological importance of GLP-1R and GIPR dimerisation. Cell surface receptors are vital for relaying information from hormones to the cell to influence cell function, and ultimately physiological responses. Receptors can form oligomers with other receptors, but whether this can influence cellular and physiological responses is not yet defined. This biology-based project aims to bridge this knowledge gap by studying the dimerisation between two related receptors involved in whole body meta ....The physiological importance of GLP-1R and GIPR dimerisation. Cell surface receptors are vital for relaying information from hormones to the cell to influence cell function, and ultimately physiological responses. Receptors can form oligomers with other receptors, but whether this can influence cellular and physiological responses is not yet defined. This biology-based project aims to bridge this knowledge gap by studying the dimerisation between two related receptors involved in whole body metabolic homeostasis. Our team will deliver new knowledge into the disciplines of pharmacology, cellular biology, metabolism and physiology, and provide interdisciplinary research training to students and junior scientists, and strengthen research collaboration within and outside of Australia.Read moreRead less
