I joined the University of Sheffield in 2016 as a Postdoctoral Research Associate in the Sheffield Myeloma Research Team, Department of Oncology and Metabolism working with Dr Andrew Chantry and Dr Michelle Lawson. In July 2019, I joined Professor Thomas Helleday’s team, as a Postdoctoral Research Associate and Project Leader using novel inhibitors to target the cancer-specific enzyme MTHFD2. Since July 2020 I have led the Cancer and Bone (CAB) Lab, developing new drugs to treat cancer with a focus on incurable cancers in bone. In 2024 I was awarded a Wellcome Trust Career Development Award, and am currently a Senior Research Fellow in the Division of Clinical Medicine. My team are developing novel strategies to kill dormant cancer cells to improve survival, and even cure, these cancers.
I completed my BBiomedSci at Monash University in 2009 focusing on pharmacology and biochemistry, receiving a High Achievement Award (top 1% of students). In 2010, I completed my Honours year in the Stem Cell Regulation Unit at St Vincent’s Institute of Medical Research (SVI), The University of Melbourne receiving first-class honours and a place on the Dean’s Honours List (first in class). I continued my research career working as a Research Assistant at SVI, followed by my PhD in the Department of Medicine (SVI), The University of Melbourne. My PhD identified that retinoic acid receptor signalling regulates mesenchymal stem cell fate and bone biology leading to altered haematopoiesis. This provided insight into a mechanism by which blood and bone cells interact in health and disease. Understanding the roles of microenvironment cells is vital for improving haematopoietic recovery following chemotherapy or bone marrow transplants and crucial for enhanced targeting of dormant tumour cells in the bone marrow exhibiting chemotherapy-resistance. I also created a new method for FACS isolation of primary bone cells, particularly cells involved in regulating haematopoiesis, improving the way diseases involving aberrant microenvironment cells (such as myeloma) are studied and understood.
I have been recognised as ‘one of the most talented young researchers in the bone field’ by the two largest international bone societies globally: the ECTS and ASBMR. Throughout my career I have been awarded >20 awards for my research including 6 Young Investigator awards, 5 Best Oral/Poster Prizes, an award for Teaching, an award for outreach activities and in 2020 I won the Faculty MDH Early Career Researcher Prize. I graduated 1st in class from The University of Melbourne, the #1 Medical School in Australia.
I have been an elected committee member of the Bone Research Society (BRS) since 2019-2023, and on the annual conference committees 2020-2022. I organised the BRS Basic Course in Bone and Cartilage Biology and Disease 2022 (Sheffield). I was the Founder, Co-President and Co-Chair of The Inaugural EMBL Australia PhD Symposium in 2014, a conference with 100 attendees and both national and international invited speakers.
- Research interests
-
My research interests focus on bone-immune-cancer interactions. I am interested in how cancer induces destructive bone disease and also how the bone microenvironment regulates tumourigenic processes like dormancy, relapse and metastasis to bone. Cancers that grow in bone are incurable, including myeloma and bone-metastatic breast and prostate cancer. My team study how cells in the bone protect cancer cells from therapy, so we can find treatments that are able to eradicate the disease. We are particularly focused on developing drugs to target dormant cancer cells and the dormancy niche.
Video shows a mouse tibia with myeloma bone disease, and the same bone after 2 weeks of treatment with a bone anabolic (TGFβ inhibitor; SD-208) and chemotherapy (bortezomib and lenalidomide). For details on this study see our paper in JBMR.
