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.

Defects In Epidermal Morphogenesis In Grainyhead-like Gene Deficient Mice
Funder
National Health and Medical Research Council
Funding Amount
$579,138.00
Summary
The cells of the skin play an essential role in the development of the mammalian embryo. They are critical for forming a protective barrier against infection and external toxins, for preventing excess fluid loss, for repair of defects and wounds , and for the generation of hair. Our laboratory has identified a family of genes that are critical for these processes. The aim of this study is to determine the relationship between these genes to further our understanding of the skin and its functions
Topical Drug Delivery Based On Porous Silicon Nanoneedles
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
There are currently a number of new drugs that can only be administered through the skin via hypodermic needles, which is costly, invasive and carries the risk of infection spread. This project proposes to develop an alternative strategy based on skin patches covered in millions of microscopic porous needles. These needles are able to puncture the skin painlessly to provide rapid and minimally-invasive administration of drugs for treatment of skin diseases, such as melanoma or psoriasis.

Summary
The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this stud ....The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this study is to determine the relationship between the genes to further our understanding of the skin and its functions. These studies have direct and important relevance to human conditions such as the congenital birth defects spina bifida and anencephaly, and infant prematurity where the skin is underdeveloped and lacks barrier function. They also have relevance to wound healing and to conditions in which hair growth is affected, such as alopecia. We believe that therapeutic interventions and prenatal diagnostic tests could evolve from these studies.Read moreRead less
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier
Funder
National Health and Medical Research Council
Funding Amount
$616,950.00
Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.
The Role Of The ABCA12 Transporter In Epidermal Lipid Homeostasis And Atherosclerosis
Funder
National Health and Medical Research Council
Funding Amount
$516,401.00
Summary
We have shown that a protein called Abca12 can control the transport of lipids in our bodies. If the function of this gene is attenuated both human and mice develop severe skin disease. Our preliminary results indicate the Abca12 protein regulates cholesterol transport in particular, and this grant will investigate how this might affect normal skin function and contribute to the heart disease atherosclerosis, one of the most common causes of death in the western world.
The Role Of Flightless In The Formation Of Scar Formation And Potential As A Target For A Novel Therapy To Reduce Scarring
Funder
National Health and Medical Research Council
Funding Amount
$60,664.00
Summary
Scarring causes significant morbidity and suffering. It can lead to pain, disfigurement and impaired physical function, which require costly ongoing care. Flightless (Flii) is a novel protein, which acts as a negative regulator of wound healing. Flii neutralising antibody treatment has been shown to improve wound healing. However, the role of Flii in scarring has yet to be investigated. This project will investigate the role of Flii in scarring and its potential as a therapeutic target.
Wounds and burn injuries are frequent injuries which can lead to deformity, disfigurement and loss of movement. The cytoskeleton is integral to the wound healing process and we have shown that a specific cytoskeletal protein, Flightless I (Flii), is an important regulator of wound repair. During the course of this fellowship I plan to further my investigations into the function and regulation of Flii in wounds and aim to develop new therapies for treating wounds and reducing scar formation.
Developing The Epidemiological Evidence Base For Eczema Prevention
Funder
National Health and Medical Research Council
Funding Amount
$476,728.00
Summary
Eczema, food allergy, asthma and hay-fever are all common conditions that are a substantial burden for individuals and families. To prevent them, we need to know their causes, but these are not yet well understood. We need better studies to identify what is causing our children to develop these allergic diseases, and rigorous studies to prevent them. In this fellowship, I will explore the causes and consequences of these conditions and test ways to prevent children from developing them.
Simulating And Stimulating The Blood-Brain-Barrier: A Platform For Investigating Non-pharmaceutical Alzheimer's Therapy
Funder
National Health and Medical Research Council
Funding Amount
$680,758.00
Summary
Alzheimer's disease is a looming public health threat worldwide. Despite the widespread acknowledgement of this issue, there are a lack of effective drugs that can slow disease progression. This project aims to investigate a new class of non-pharmaceutical treatment methods based on controlled acoustic, electrical and optical stimulation methods to treat and reverse the base causes of Alzheimer's disease.
