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
Hyperpolarised gas functional lung and molecular imaging. This project will produce a polariser to generate magnetised gas for research with magnetic resonance imaging (MRI). This allows imaging of normal and abnormal lung ventilation and circulation in animal and humans. The use of these hyperpolarised gases can also be used to tag specific molecules and increase understanding of lung metabolism.
Impaired innate antiviral immunity predisposes toward virus-associated airway remodelling in childhood asthma. Increased airway smooth muscle (ASM) mass is the major pathological feature of asthma that causes poor lung function. ASM remodelling occurs in early life, is refractory to current treatments and persists into later life. Severe respiratory virus infections in early life are a major risk factor for the development of asthma, yet it remains to be determined whether viruses promote ASM re ....Impaired innate antiviral immunity predisposes toward virus-associated airway remodelling in childhood asthma. Increased airway smooth muscle (ASM) mass is the major pathological feature of asthma that causes poor lung function. ASM remodelling occurs in early life, is refractory to current treatments and persists into later life. Severe respiratory virus infections in early life are a major risk factor for the development of asthma, yet it remains to be determined whether viruses promote ASM remodelling. Previous studies have developed a unique mouse model of childhood asthma and discovered the molecular mechanism by which this tissue tropism develops in response to virus infection. This project will identify new targets for immunomodulation and design new biologics to block ASM remodelling and the deleterious effects of respiratory virus infection in asthmatic subjects.

Single vesicle dynamics and the control of secretion. This project investigates secretion and tests a new model for secretory control. Its outcomes will further our knowledge in this important area and may be significant in the longer term for the treatment of secretory diseases.
Rhinovirus impairs physiological and immunological lung development and causes exacerbation of allergic airways disease. Rhinovirus (RV) infections account for around 90 per cent of asthma exacerbations, yet the mechanisms behind this are unknown. This project will use mouse models to study the effects of early life RV infection and allergic sensitisation on respiratory and immunological development, with the expectation that early life RV infection disrupts anitgen presenting cell function.
Neural circuits that mediate fear conditioning and extinction. Understanding of how the brain processes, stores and retrieves information and produces behavioural outcomes is in its infancy. This project will use electrophysiology and molecular techniques to understand the circuits that mediate one form of emotional learning.

Facility for analysing behaviour, learning and motor skills in animal models. Mental disorders are one of the largest costs to the community today and account for more than 50% of the time lost from work. Moreover, these disorders are disabling conditions that relate to fundamental, basic questions of identity and individuality. This collaborative behavioural facility at The University of Queensland will underpin excellent research into how neurological changes affect behaviour and thinking, pro ....Facility for analysing behaviour, learning and motor skills in animal models. Mental disorders are one of the largest costs to the community today and account for more than 50% of the time lost from work. Moreover, these disorders are disabling conditions that relate to fundamental, basic questions of identity and individuality. This collaborative behavioural facility at The University of Queensland will underpin excellent research into how neurological changes affect behaviour and thinking, provide infrastructure to test current models on brain functions, and support the development of new compounds to treat these disorders, thus resulting in significant national and community benefits in improved health outcomes and increased work productivity.Read moreRead less
The grand challenge of predicting human movement energetics. This Project aims to advance our understanding of how the neuromuscular system uses energy during movement by exploring the interplay of different factors that influence movement energetics. The Project will explore different levels of organisation; from how muscle fibres consume energy to how those fibres interact and are subsequently controlled within a complex neuromuscular system. Expected outcomes of this Project will be an improv ....The grand challenge of predicting human movement energetics. This Project aims to advance our understanding of how the neuromuscular system uses energy during movement by exploring the interplay of different factors that influence movement energetics. The Project will explore different levels of organisation; from how muscle fibres consume energy to how those fibres interact and are subsequently controlled within a complex neuromuscular system. Expected outcomes of this Project will be an improved capacity to predict energy expenditure of the vast array of movements that humans perform. This will enable accurate monitoring of human energy expenditure and will provide benefits for individualised exercise prescription, enhancing work productivity or designing devices to augment human performance.Read moreRead less
Sterile inflammation as a determinant of adaptive immunity. When we injure ourselves, the site of injury becomes inflamed, which may help healing or cause trouble. This project aims to understand how the normal response to injury is controlled and why the process may sometimes go wrong.
The sulfate anion transporter gene, Sat1: physiology, regulation and developmental expression. Sulfate is an essential nutrient for cell growth and survival. The kidneys and liver help regulate sulfate levels in the body, by yet unknown mechanisms. Recently, we cloned a gene, Sat1, expressed in mouse liver and kidneys, which may be responsible for body sulfate maintenance. In this study, we will determine the physiological importance of Sat1 in cell growth/survival and in controlling body sulfa ....The sulfate anion transporter gene, Sat1: physiology, regulation and developmental expression. Sulfate is an essential nutrient for cell growth and survival. The kidneys and liver help regulate sulfate levels in the body, by yet unknown mechanisms. Recently, we cloned a gene, Sat1, expressed in mouse liver and kidneys, which may be responsible for body sulfate maintenance. In this study, we will determine the physiological importance of Sat1 in cell growth/survival and in controlling body sulfate levels. We will generate and characterise a Sat1 lacking mouse, study its expression during development and its effects on other genes. We will elucidate how body sulfate levels are maintained and its importance in cell growth/development.Read moreRead less
Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studi ....Estrogen signalling in gonadotropes.

In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms.
