Summary
Bone diseases affect more people than any other group, carry a huge and growing socioeconomic cost, yet their aetiologies are not fully determined. This study will elucidate the role of the resident bone cell, the osteocyte, in prevalent bone diseases such as osteoporosis, osteoarthritis and related orthopaedic conditions, rheumatoid arthritis, bone cancer, and in systemic metabolism. The goal is to provide the knowledge and mechanisms for developing improved treatments and patient outcomes.
Bone Growth For Healthy Development: Physiology, Pathophysiology, And Regeneration

Summary
Musculoskeletal damage is a major burden on individuals and our health care system. My research program will focus on improving bone health in three important areas: (1) children’s growth plate injury and growth defects; (2) bone loss and bone marrow defects from cancer chemotherapy; (3) ensuring that bone grows healthily in early life. The overall intent of this research is to develop new therapies when bone doesn’t grow well, or is damaged.
Assessment Of The Properties Of Mesenchymal Stem Cells And Their Role In Skeletal Tissue Repair And Disease

Summary
There is currently a steady increase in surgical intervention and rehabilitation therapy for bone related fractures due to trauma or osteoporosis as a consequence of an aging population. Bone regeneration involves the coordinated participation of skeletal precursor cells, blood vessels and immune cells recruited from the surrounding tissues. This proposal examines the mechanisms mediating the maintenance and recruitment of skeletal precursor cells to sites of bone damage.
Regulation Of Normal And Malignant Haematopoiesis By The Bone Marrow Environment

Summary
This project will identify factors within the bone marrow that regulate blood and immune cell formation. These include oxygenation and novel proteins identified in the applicant’s laboratory. How these factors from the bone marrow influence the behaviour of normal blood forming cells (called haematopoietic stem cells), and the progression of leukaemia and the response of leukaemia to chemotherapy treatments will be investigated. New drugs that interfere with these new factors will be tested for ....This project will identify factors within the bone marrow that regulate blood and immune cell formation.

I am a biochemical geneticist working on inherited disorders that affect the musculoskeletal system. My major focus is determining the molecular basis of muscular dystrophies and bone and cartilage disorders.
Tissue Engineering Approach To Musculoskeletal Regeneration

Funding Amount
$622,655.00
Summary
Over the next few decades there is an anticipated steady increase in surgical intervention for bone, cartilage and tendon damages due to trauma or osteoporosis as a consequence of an aging population. These damages cause chronic pain, immobility, restricted activities, and, sometimes, death and are a considerable financial burden to the Australian Health System.
Development Of Novel Resorbable Biomaterials For Regeneration Of Human Tissue

Funding Amount
$601,484.00
Summary
Large skeletal defects resulting from congenital defects or disease processes are difficult to regenerate and represent a major financial burden to our health system. Bone graft treatments are widely used but have considerable drawbacks. Available synthetic alternatives lack the physical/biological properties necessary. We have developed new scaffolds with improved mechanical/biological properties for bone and cartilage regeneration.
Research Fellowship: Immunoregulation And Immunity To Viral Infection

Funding Amount

Summary
Award of this fellowship will ensure the continuation of a highly productive research program that over the last 15 years has made numerous seminal contributions to understanding the immune responses generated during viral infection. This multidisciplinary, highly collaborative program seeks to use this knowledge to develop effective therapies, both cellular and gene therapy-based, to treat viral infections and their complications by harnessing the immune system.
My work focuses on cells of the immune system that act as sentinels on the lookout for invading pathogens and danger. These cells are called dendritic cells. I am particularly interested in understanding how these cells function within the bone marrow environment and how they may sense viral infection or cancerous cells within this tissue. We aim to understand their function in specific diseases including Lupus and in pre-leukemia conditions, and also in infectious and parasitic diseases.
