Susan Millard

Dr Susan Millard serves as an Honorary Fellow and Lecturer at the Mater Research Institute–University of Queensland (MRI-UQ), within the Faculty of Health, Medicine and Behavioural Sciences at the University of Queensland. She holds a Doctor of Philosophy from the University of Adelaide. Her research focuses on the roles of macrophages in bone marrow microenvironments, hematopoiesis, inflammation, bone development, and hematopoietic stem cell niches. Key areas include osteal macrophages in bone homeostasis, fracture repair, osteoporosis pathology, hematopoietic stem cell engraftment post-transplantation, and macrophage responses to aging and infection.

Millard has produced 59 scholarly works catalogued in UQ eSpace from 2004 to 2025, predominantly journal articles and conference publications. Prominent publications encompass 'Fragmentation of tissue-resident macrophages during isolation confounds analysis of single-cell preparations from mouse hematopoietic tissues' (2021, Cell Reports), 'Macrophages form erythropoietic niches and regulate iron homeostasis to adapt erythropoiesis in response to infections and inflammation' (2021, Experimental Hematology), 'Role of macrophages and phagocytes in orchestrating normal and pathologic hematopoietic niches' (2021, Experimental Hematology), 'Treatment with a long-acting chimeric CSF1 molecule enhances fracture healing of healthy and osteoporotic bones' (2021, Biomaterials), 'Osteal macrophages support osteoclast-mediated resorption and contribute to bone pathology in a postmenopausal osteoporosis mouse model' (2021, Journal of Bone and Mineral Research), 'Macrophage heterogeneity in the single cell era: facts and artefacts' (2023, Blood), 'Induction of osteoblast apoptosis stimulates macrophage efferocytosis and paradoxical bone formation' (2024, Bone Research), and 'Mutation in the rat interleukin 34 gene impacts macrophage development, homeostasis, and inflammation' (2025, Life Science Alliance). She has obtained funding through an NHMRC IDEAS Grant (2022–2026) titled 'Increasing hematopoietic stem cell niches post transplantation through enhancing bone marrow macrophage resilience and regeneration mechanisms' and an ANZBMS/BHF Project Grant (2026–2027) for 'Rejuvenation of bone marrow macrophages to enhance skeletal repair in aging'.
