Engineering cartilage homeostasis in health and disease. Arthritis is a common, painful and often debilitating disease affecting 16% of the Australian population and costing this community $11 billion every year. It is not well understood why cartilage degenerates into joint disease, nor how it may be reversed - partly due to the large number of mechanisms involved. This project aims to overcome this complexity by developing a computational model of cartilage that can integrate the various mech ....Engineering cartilage homeostasis in health and disease. Arthritis is a common, painful and often debilitating disease affecting 16% of the Australian population and costing this community $11 billion every year. It is not well understood why cartilage degenerates into joint disease, nor how it may be reversed - partly due to the large number of mechanisms involved. This project aims to overcome this complexity by developing a computational model of cartilage that can integrate the various mechanisms of cartilage degradation. New experiments will be used to validate the model and test predictions. The model developed will provide fundamental insights into what is required for the maintenance of healthy cartilage, and what happens in injury-induced degradation of cartilage.Read moreRead less
Program evaluation of the osteoarthritis awareness hub. Persons with osteoarthritis generally have poor knowledge about their disease and its appropriate management. The aim of this project is to evaluate whether improved knowledge, and management decisions of persons with osteoarthritis, can ultimately lead to improved health outcomes.
Pathogen sensing in systemic inflammatory disease. The initiation, amplification and quenching of an immune response is a carefully orchestrated process that eliminates invading pathogens while minimising collateral damage to host tissues. This research focuses on proteins that restrict immune responses to prevent inflammatory diseases such as rheumatoid arthritis, psoriasis and inflammatory bowel disease. This work will also explore the role of a potassium channel that protects the host from or ....Pathogen sensing in systemic inflammatory disease. The initiation, amplification and quenching of an immune response is a carefully orchestrated process that eliminates invading pathogens while minimising collateral damage to host tissues. This research focuses on proteins that restrict immune responses to prevent inflammatory diseases such as rheumatoid arthritis, psoriasis and inflammatory bowel disease. This work will also explore the role of a potassium channel that protects the host from organ failure during an infection, by coupling the energy requirements of mounting an immune response, and organ function. This may have important implications for the management of sepsis, a systemic immune response associated with infection and the leading cause of death in critically ill patients.Read moreRead less
Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applicati ....Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling.

Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applications. This research proposal closely aligns with one of the major national research priorities, i.e., promoting and maintaining good health (ageing well, ageing productively). The research project is aimed to understand how mechanically induced loading may activate remodeling of bone.

Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation ....Multi-scale modeling of transport through deformable porous materials. Understanding solute transport through porous materials is essential because it provides a technical basis for answering many important questions in society today-how can humans avoid 'brittle bones', how to design durable infrastructure, how to safely store wastes (e.g. hazardous and municipal). Solution of each of these problems requires innovation in model development, new method of analysis, and insightful interpretation of results. While theoretical developments of this project are general, in the sense that they are not restricted to particular engineering disciplines, the four chosen applications closely align with two major research priorities namely An Environmental Sustainable Australia and Promoting and Maintaining Good Health.Read moreRead less
Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine ....Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine how evolution works at the DNA level. This proposal will determine if animals that develop identical skull shapes, also show identical changes in their DNA. The findings will define new developmental genes and explain how selection, adaptation and evolution works at the DNA level. Read moreRead less
Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their inter ....Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their interaction with drugs is essential in order to develop new therapies and to effectively design novel biological compatible bone implants. This research proposal closely aligns with national research priority two, i.e., promoting and maintaining good health (ageing well, ageing productively).Read moreRead less
