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.

Unified framework of intestinal motility. The project aims to establish how a few fundamental mechanisms determine the large repertoire of intestinal motor patterns responsible for moving nutrients along the digestive tract. The project will combine experimental and theoretical data, with biomechanical and electrophysiological models to create a new understanding of this essential function of the body.

Calcium signalling by intracellular calcium stores in rabbit, mouse and man: implications for muscle performance and athletic ability. This project addresses essential vital life functions such as respiration and movement and factors that determine whether muscles are better suited to weight lifting, endurance or sprint activities. The outcome will fill an information gap and provide therapeutic targets, significant in medicine, sports and veterinary science.
Amino acids as nutrients - the molecular basis of amino acid absorption in kidney and intestine. Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face. Most studies in nutrition focus on fat and carbohydrates because of their direct involvement in obesity and diabetes. Proteins and the resulting peptides and amino acids, however, form 10-15% of our nutritio ....Amino acids as nutrients - the molecular basis of amino acid absorption in kidney and intestine. Nutrition is a critical factor for well being and health. This is highlighted by the increase in frequency of type II diabetes and the obesity problem that all societies with a western diet face. Most studies in nutrition focus on fat and carbohydrates because of their direct involvement in obesity and diabetes. Proteins and the resulting peptides and amino acids, however, form 10-15% of our nutrition. At a time where protein-rich diets are recommended to fight obesity and diabetes, it is important to understand the basis of protein absorption and metabolism. This project investigates the mechanism and mediators of amino acid absorption in kidney and intestine. Read moreRead less
How triadin and junctin communicate with ryanodine receptors deep within a calcium store to determine skeletal muscle contraction.

Structural Determinants of an Intracellular Calcium Store. Understanding the molecular interactions between key proteins in calcium signalling in muscle and the heart will allow calcium signalling to be used as a platform for a variety of purposes. These include reducing the debilitating effects of changes in calcium signalling and muscle performance in aging and in genetically- or drug-induced disorders. The project will have benefits for Australian biotechnology since it will facilitate the de ....Structural Determinants of an Intracellular Calcium Store. Understanding the molecular interactions between key proteins in calcium signalling in muscle and the heart will allow calcium signalling to be used as a platform for a variety of purposes. These include reducing the debilitating effects of changes in calcium signalling and muscle performance in aging and in genetically- or drug-induced disorders. The project will have benefits for Australian biotechnology since it will facilitate the design of novel compounds for treating muscle disorders in animals and humans, for improving meat quality and for use as insecticides. The project will facilitate graduate and undergraduate training in basic science with exposure to biotechnology, through our commercial partner Biotron.Read moreRead less
Neuronal activity underlying efficient sensory processing. This project aims to study how neuronal activity in the sensory cortex efficiently represents the external world. Operating with a finite quantity of attentional resources, the brain needs to prioritise processing to provide important information about a situation.

Physiology of oxygen transport in the mammalian kidney. This project aims to improve understanding of oxygen regulation in renal tissue and knowledge of the physiology of the kidney. The mammalian kidney receives more oxygen than it uses or needs, and yet renal tissue is commonly found to be hypoxic. This project proposes that oxygen transport to the renal tissue is limited by blood vessel surface area. The project expects to generate anatomical data currently missing from the renal physiology c ....Physiology of oxygen transport in the mammalian kidney. This project aims to improve understanding of oxygen regulation in renal tissue and knowledge of the physiology of the kidney. The mammalian kidney receives more oxygen than it uses or needs, and yet renal tissue is commonly found to be hypoxic. This project proposes that oxygen transport to the renal tissue is limited by blood vessel surface area. The project expects to generate anatomical data currently missing from the renal physiology community, and potentially change the accepted story of oxygen homeostasis in the kidney. This will provide significant benefits, such as the provision of the foundational physiological science behind a determinant of kidney health and its flow-on impact to quality of life.Read moreRead less
Understanding the mechanisms of ion conduction and drug action in voltage gated sodium channels. Voltage-gated sodium channels initiate electrical impulses in nerve and muscle and are the target of many local anaesthetic, anti-epileptic and anti-arrythmic drugs. The publication of atomic resolution structures of homologous proteins from bacteria in the last 18 months has now made it possible to gain a detailed understanding of how these channels work, and how they are influenced by drugs.

The publication of atomic resolution structures of homologous proteins from bacteria in the last 18 months has now made it possible to gain a detailed understanding of how these channels work, and how they are influenced by drugs. This project aims to determine the basis of ion permeation and selectivity in the channels and explain the mechanisms of action for a number of common drugs. This will provide a foundation for future drug development to target specific channels for improved treatment of epilepsy, chronic pain and arrythmias. Read moreRead less
