RESEARCHER PROFILE
Filmed in Clayton, Victoria, Australia | December 2024
Dr. Maree Bilandzic is a molecular cancer biologist dedicated to advancing the understanding and treatment of ovarian cancer (OC). Her research addresses critical gaps in OC treatment by investigating the mechanisms behind metastasis, chemotherapy resistance, and tumour recurrence. By utilising innovative methodologies and disease-representative models, Dr. Bilandzic has pioneered the identification and characterisation of leader cells (LCs)—a unique, stem-like subpopulation within tumours that plays a crucial role in OC progression.
LCs facilitate “collective invasion,” enabling tumour cells to spread by interacting with their environment and influencing immune responses. Importantly, Dr. Bilandzic’s research demonstrated that these LCs are resistant to standard therapies and become more prevalent following treatment. Despite their significance, there are currently no targeted therapies for LCs, highlighting the urgent need for novel therapeutic strategies.
Her work focuses on meeting the unmet clinical needs of patients with metastatic and therapy-resistant OC. By disrupting LCs, Dr. Bilandzic’s team has shown enhanced chemosensitivity, limited tumor spread, and altered immune responses—demonstrating the therapeutic potential of targeting LCs.
She has over $3.5 million in commercial funding and additional support exceeding $2 million from organisations such as the Ovarian Cancer Research Foundation, CASS Foundation, Fielding Foundation, Equity Trustees and Perpetual Impact grants. Dr. Bilandzic is well-positioned to expand her research into other epithelial cancers, aiming to develop effective treatments that can significantly improve patient outcomes across multiple cancer types. Key areas of focus include understanding LC roles in immune modulation, invasion, metastasis, and chemotherapy resistance.

Relationship between language-literacy skills and mental health
In an innovative move towards enhancing mental health services, Associate Professor Amanda Neil and team, supported by the RHH Research Foundation, are undertaking a crucial study on language-literacy skills of patients within mental health care settings. This year-long project, which commenced in April 2024, seeks to unravel to what extent, where and for whom language-literacy skills are being considered in Tasmanian mental health service provision.
