Professor Pettit leads the Bones and Immunology Research Group at Mater Research Institute-UQ and is Director of Biomedical Research for Mater Research. Professor Pettit has led multidisciplinary research discovering intersecting biological mechanisms across the fields of immunology, rheumatology, cancer biology, haematology and bone biology. Professor Pettit is currently a UQ Amplify recipient associated with an ARC Future Fellowship, 2017-2020 and CIA on an NHMRC Ideas Grant, 2022-25. Major contributions led by Professor Pettit include the paradigm shifting discovery of a novel population of resident macrophages, osteal macrophages (osteomacs), and their role in promoting bone formation and bone regeneration after injury. Her team have published over 17 manuscripts based on this original discovery (with over 1700 citations) including translation of this basic research discovery toward eluciating novel disease mechanism from cancer bone metastasis to osteoporosis. This also led to the novel discovery of bone marrow resident macrophage contributions to supporting blood stem cells niches and the key role that these cells play in protecting this vital niche from cancer therapies. Bone marrow and specifically haematopoietic stem cell damage is one of the most serious and life-threatening side effects of cancer therapies. Here discoveries are cited in over 117 patent documents and she is currently collaborating with a major pharmaceutical partner.
Professor Pettit's leadership and achievements have been recognised through multiple awards including the 2019 UQ Faculty of Medicine Leader of the Year (Academic), Women in Technology 2018 Life Sciences Outstanding Achievement Award and becoming a Fellow of the American Society of Bone and Mineral Research. Professor Pettit has been invited to give numerous presentations at national and international conferences including Seoul Symposium on Bone Health, Asia-Pacific League of Associations for Rheumatology Congress and a prestigious American Society of Bone and Mineral Research Meet-the-Professor session. Professor Pettit is and Associate Editor for the Journal of Bone and Mineral Research, is an past Council member for the Australian and New Zealand Bone and Mineral Society, and chairs or serves on numerous committees including the Association of Australian Medical Research Institutes Gender Equity, Diversity and Inclusion Committee. PhD candidates under Professor Pettit's supervision have all been supported by scholarships (including 2 x NHMRC), received numerous local and national awards (e.g. Dr Alexander, ASMR QLD Premier Postgraduate Award, 2011 and Dr Lena Batoon won the UQ Faculty of Medicine Graduate of the Year Award, 2021), all had high quality first author publications at completion and 2 received UQ Dean’s Commendations.

Deconvoluting Tissue Resident Macrophage Biology
Project only open to Australian Domestic Applicants at this time with competitive stipend on offer.
Analysis of single cell preparations from tissues is a mainstay of biological discovery research. Particularly in the current era of costly investment in increasingly high dimensional analysis of single cell samples toward generation of publicly available data sets. The team exposed an unrecognised technical phenomenon that has high potential to substantively compromise single cell data accuracy across a broad range of research fields including immunology and haematology. Specifically, tissue resident macrophages are fragmented during haematopoietic single cell suspension preparation and leave behind encapsulated remnants containing membrane and cytoplasmic molecules attached to other cells they were interacting with in situ. This phenomenon profoundly compromises accurate analysis of the data generated. Using this unique perspective, the project aims to 1) expose how widespread this phenomenon is in a diverse range of tissues across age; 2) develop optimised approaches to eliminate macrophage fragmentation during haematopoietic tissue single cell preparation; and 3) take advantage of this technical phenomenon to achieve a substantive knowledge gain in understanding bone marrow macrophage specialisation.
The outcome of this research is a broad spectrum increase in the fidelity of biology research that utilises this common approach. This will elevate translatability of research outcomes and ultimately public confidence in the Australian biology research sector. It will create opportunity to collaborate with industry toward improved development of relevant reagents and instrument technology and inform development of digital tools to deconvolute this phenomenon when analysing big data sets.

Deconvoluting Tissue Resident Macrophage Biology
Project only open to Australian Domestic Applicants at this time with competitive stipend on offer.
Analysis of single cell preparations from tissues is a mainstay of biological discovery research. Particularly in the current era of costly investment in increasingly high dimensional analysis of single cell samples toward generation of publicly available data sets. The team exposed an unrecognised technical phenomenon that has high potential to substantively compromise single cell data accuracy across a broad range of research fields including immunology and haematology. Specifically, tissue resident macrophages are fragmented during haematopoietic single cell suspension preparation and leave behind encapsulated remnants containing membrane and cytoplasmic molecules attached to other cells they were interacting with in situ. This phenomenon profoundly compromises accurate analysis of the data generated. Using this unique perspective, the project aims to 1) expose how widespread this phenomenon is in a diverse range of tissues across age; 2) develop optimised approaches to eliminate macrophage fragmentation during haematopoietic tissue single cell preparation; and 3) take advantage of this technical phenomenon to achieve a substantive knowledge gain in understanding bone marrow macrophage specialisation.
The outcome of this research is a broad spectrum increase in the fidelity of biology research that utilises this common approach. This will elevate translatability of research outcomes and ultimately public confidence in the Australian biology research sector. It will create opportunity to collaborate with industry toward improved development of relevant reagents and instrument technology and inform development of digital tools to deconvolute this phenomenon when analysing big data sets.
