Professor Radford leads the Cancer Immunotherapies Group at Mater Research Institute-UQ. Her research interests are focussed on understanding how the human immune system can be trained to recognise and fight cancer for the development of vaccines and immunotherapies.

Professor Radford’s leadership and globally-recognised expertise in the fields of human dendritic cell (DC), immuno-oncology, immunotherapy, cancer vaccines and humanised mice is evidenced by 59 publications in top journals including J Exp Med, Nat Immunol, Immunity and more than 50 invitations to speak. She has attracted >$6 million in funding as a Chief Investigator and >$5 million as a Co-Investigator. She has been recognised by awards including NHMRC CDF2 (2011-2014), Mater Medal for Outstanding Research Contribution 2015, ASI Miller Award 2018, a 2021 Fulbright Future Fellowship and Fellowship of the QLD Academy of Arts and Science.

Professor Radford’s expertise include development and clinical trial of the one of the first vaccines to use human circulating blood conventional DC (cDC) for cancer immunotherapy that was translated to a first-in-human clinical trial for metastatic prostate cancer. Her group was the first to functionally characterise the human cDC1 subset) and propose their potential as next-generation cancer vaccines, a finding described by international leaders as “a needle in the cancer vaccine haystack”. She has pioneered techniques to isolate cDC1s from human tissues, culture them from CD34 progenitors in vitro and in humanised mice in vivo and developed a suite of assays to interrogate their phenotype and function, including priming of human tumour specific immune responses. These have been applied to develop novel cancer vaccines that target human cDC1 in vivo, that are now being translated for commercialisation and clinical trial.

Professor Radford has pioneered the development of innovative models that faithfully replicate the human immune system (humanised mice). These are in high demand globally to enhance research impact and increase the speed and accuracy of immunotherapy drug development in oncology, autoimmunity, inflammatory and infectious disease. She has applied these to wide range of applications including hematopoeisis, cancer immunotherapy and autoimmune disease.

Professor Rae received her PhD in 2007 in the area of reproductive physiology and has been working in the area of Aboriginal and Torres Strait Islander maternal and infant health and chronic disease since that time. She began as the Group Lead for the Indigenous Health Research group at the Mater Research Institute in a role that bridges the Mater, University of QLD and is actively growing partnerships with the Aboriginal community-controlled health sector in QLD. The importance of maternal health for Indigenous communities has been identified as a critical national research priority by Indigenous communities. Her work has had a multidisciplicinary nature and while always focused on the health of Indigneous Australians she has published in areas including pregnancy and birth outcomes, nutrition, psychosocial health, growth and development during infancy, the use of arts in health education to name a few.She has a particular passion for working in partnership to co-design research projects that support improving health outcomes for Aboriginal and Torres Strait Islanders. Her specific focus has primarily been to develop programs that reduce chronic diseases which afflict Aboriginal people more commonly through early detection and diagnosis, health education, and developing a thorough understanding of risk factors that impact on this community. She has mentored her team of staff and students to co-produce and co-disseminate findings from these programs of work and to build research capacity for all team members including those who identify as Indigenous and for those from rural locations of research studies.

Prior to her role at Mater Research, she was the inaugaral Director of the Gomeroi gaaynggal program (2007-2019), which had two major programs of work 1. ArtsHealth for community engagement, health education and health promotion and 2. A Health research program for understanding the development of chronic disease in the Indigenous community through the Gomeroi gaaynggal cohort. Program 1 was successful in transitioning its funding to local Aboriginal community-controlled sector in Tamworth (2019). Prior to its transition, she led a community focussed ArtsHealth program to improve health knowledge, particularly in the areas of social and emotional wellbeing in the community, with the assistance of a team of beginning Indigenous researchers. Over 100,000 hours of community education were delivered through this program. 2. The Gomeroi gaaynggal cohort work has involved the recruitment and retention of a prospective longitudinal cohort of Indigenous women from pregnancy through until the infants are 10 years of age highlighting her expertise in working with Indigenous families during their antenatal and early childhood years. The importance of maternal health for this population is a critical priority to improving the life-long health of the Indigenous communities of Australia.

Delineation of osteal macrophage function in the bone microenvironment: dual roles in bone dynamics and stem cell niches.

Bone and joint diseases are a national and international health and research priority costing the Australian health system over $10 billion annually. The bony skeleton is a dynamic metabolically active tissue that is continuously remodelled and repaired to maintain calcium homeostasis and structural integrity. The microenvironment at the inner surface of long bones (endosteum), including the bone matrix and associated bone lining cells, is crucial to the dynamic processes of bone modelling and remodelling. I have recently characterized 'osteomacs' as a resident tissue macrophage population within bone lining tissues and have shown that they promote bone mineralization in vitro and are necessary for the maintenance of bone forming osteoblasts in vivo. Thus osteomacs are cellular constituents of endosteal niches and play an osteoblast-support function in this microenvironment. We are investigating the unique phenotype and expression profile (mRNA and protein) of osteomacs in order to fully delineate their functional potential in bone dynamics.

Recently it has been shown that the endosteal environment is also essential for the maintenance of mesenchymal stem cell (MSC) and haematopoietic stem cell (HSC) niches. Osteoblasts need to be present on the bone surface to ensure HSC maintenance in the endosteal niche. Therefore we hypothesised that osteomacs, as a consequence of their presence in the niche and osteoblast support-function, contribute both indirectly and directly to the generation of this stem cell nursery. We have shown that loss of osteomacs and subsequently osteoblasts occurs during G-CSF induced HSC mobilization. Importantly, in vivo depletion of osteomacs (using transgenic Mafia mice) also causes marked egress of HSC from bone marrow into the blood and spleen. These data provide compelling support that osteomacs are required for maintenance of osteoblast bone forming surfaces and provide caretaker support for the endosteal stem cell niches.

My research team has a number of projects that aim to understand the cellular architecture of the endosteal stem cell niches and the role of osteomacs in this environment. This is an essential step toward enhancing clinical HSC mobilization options in order to improve bone marrow transplantation outcomes in multiple myeloma and lymphoma and also ensuring that the promise of MSC therapy is translated into a clinical reality.
