Summary
Millions of scripts are filled for treatment of osteoporosis. However, there is no way of knowing if these drugs are right for these individuals, if it improves bone strength or are actually doing harm. Bone density measurement is of limited value. We have developed a new analysis method that measures changes in bone structure that tell us if the treatment is or is not working so alternative treatment can be used. The aim of this study is to test this new method.

Summary
Osteoporosis is a major disease affecting Australians. Whilst there are a number of drugs available that will reduce bone loss, there are few drugs available that build new bone, and little is known of the action of these drugs. New targets have been identified that modulate bone formation, and this project aims to validate these in appropriate models and determine their mechanism of action.
Optimising Bone Regeneration Using Advanced Design And Fabrication Technologies

Summary
The aging population has produced a rapidly increasing demand for synthetic implants that can regenerate lost or diseased bone. This project will produce an implant that represents a viable alternative to bone autografts and allografts with broad applications for the repair of large or challenging bone defects. Such an achievement will have significant healthcare benefits by reducing patient morbidity and recovery time, and improving long-term outcomes.
Determining The Influences Of Cell Stress And Heat Shock Factor-1 Action In Osteoclast Formation And Pathological Bone Loss.

Summary
Cancer and rheumatoid arthritis cause painful bone destruction. This occurs due to increased numbers of bone destroying cells called osteoclasts. We found stress responses in bone cells can increase osteoclast numbers by activating proteins inside the bone cells that encourage osteoclasts to form. We will thus study whether cell stress blocking drugs might stop bone loss. As arthritis and cancer both cause stress responses, this work could identify a new way that such diseases affect bone.
I am an orthopaedic surgeon and clinician-scientist based at Sydney’s largest children’s hospital. My goal is to improve treatments for children with traumatic injuries and bone deformity. I have worked in bone research for over 20 years. My current research interests are finding new treatments for drug-resistant bacterial infections, treating genetic bone disease, and developing new medical devices to help children’s bones grow straight.
