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.

Versatile elastin based hybrid hydrogels for chondrocyte transplantation and repair. Cartilage repair is often limited after significant trauma, sports injury and disease. This project will generate a new family of hybrid biomaterials constructed by precisely blending natural and synthetic components. These novel biomaterials will establish the foundation for manufactured prefabrication and in situ injection to promote healing.
The role of heparan sulfate proteoglycans in the control of osteoblast phenotype. Very little is known about how bone cells progress from a naive precursor state, through differentiation and then maturation into adult cells. We wish to purify sugars from the bone cell membrane, extracellular matrix and culture medium, and examine the cellular response following the addition of these various sugar fractions to osteoblast cell cultures in combination with known growth factors. If we can control ....The role of heparan sulfate proteoglycans in the control of osteoblast phenotype. Very little is known about how bone cells progress from a naive precursor state, through differentiation and then maturation into adult cells. We wish to purify sugars from the bone cell membrane, extracellular matrix and culture medium, and examine the cellular response following the addition of these various sugar fractions to osteoblast cell cultures in combination with known growth factors. If we can control the progression of osteoblastic cells through the phases of recruitment, proliferation, differentiation and maturation by the addition of specific sugar fractions then we can potentially control bone formation.Read moreRead less
Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a cru ....Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a crucial role in the progression of this disease by increasing the rate of bone-thinning. We will make compounds to slow down this enzyme. This project will provide the basis for the future development of new and improved drugs to treat osteoporosis.Read moreRead less
Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, an ....Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, and what target molecules they act on. A better understanding of these factors will increase the chances of finding cures and developing better treatments for important inflammatory diseases of the ageing population.Read moreRead less
Novel Glycoproteomic based diagnostic technology for identifying cartilage tissue turnover and repair. Osteoarthritis is a long-term debilitating disease, which results in the loss of cartilage in the joints, leading to pain and disability. This is a major problem and cost in ageing societies, yet the mechanisms of joint deterioration are still poorly understood. This project will investigate proteoglycans and proteoglycan fragments produced by cells of the joint, detailing the structure of th ....Novel Glycoproteomic based diagnostic technology for identifying cartilage tissue turnover and repair. Osteoarthritis is a long-term debilitating disease, which results in the loss of cartilage in the joints, leading to pain and disability. This is a major problem and cost in ageing societies, yet the mechanisms of joint deterioration are still poorly understood. This project will investigate proteoglycans and proteoglycan fragments produced by cells of the joint, detailing the structure of their sugar components, and map which regions are interacting with antibodies. Understanding these proteoglycan fragments will help us to determine their role in disease progression, and application of this knowledge will assist in the development of an early diagnostic for osteoarthritis.Read moreRead less
Rapid functional analysis of genes involved in skeletal development. Abnormalities of the skeleton are of enormous clinical significance in terms of both number of individuals affected and the cost of treatment. Data derived from this project will underpin targeted research on the mechanisms of inherited and common diseases of cartilage and bone, yielding novel diagnostic and therapeutic targets. In addition, the improved knowledge of cartilage and bone cell development will inform new approache ....Rapid functional analysis of genes involved in skeletal development. Abnormalities of the skeleton are of enormous clinical significance in terms of both number of individuals affected and the cost of treatment. Data derived from this project will underpin targeted research on the mechanisms of inherited and common diseases of cartilage and bone, yielding novel diagnostic and therapeutic targets. In addition, the improved knowledge of cartilage and bone cell development will inform new approaches for developing stem cell therapies and the production of novel biomaterials for the repair of bones and joints. The outcomes of this study will therefore benefit the full spectrum of society from infants to the aged.Read moreRead less
Proteomic techniques to assess oxidative stress in muscle wasting diseases. Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits. Oxidative stress ....Proteomic techniques to assess oxidative stress in muscle wasting diseases. Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits. Oxidative stress is a key intermediary in muscle wasting. This PhD project examines a possible mechanism by which oxidative stress causes muscle wasting. An appropriately tailored therapy to minimise oxidative stress has the potential to ameliorate loss of muscle mass.
