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.

Impact of NextSense Institute Research in the field of sensory disabilities
NextSense has a 165 year history of providing services and education for individuals with sensory impairments. With the support of donations, NextSense provides vital support for children and adults, more cochlear implants than any other service in Australia, and is a world leader for research, technology and professional education in the fields of visions and hearing loss.
NextSense clinicians are actively involved in a number of leading research projects—both independently and in collaboration with local and international organisations. The NextSense Institute, part of NextSense is Australia’s leading centre for research and professional education in the field of sensory disabilities.

Ocular disease and early onset myopia
Dr Mountford has successfully established Western Australia’s first and only ocular genetic screening platform using zebrafish and utilises this model to help elucidate some of the complex gene-environment interactions responsible for the development of myopia.

Investigating invasive lobular carcinoma and metaplastic breast cancer sub-types
Assoc Prof McCart Reed is the scientific lead on an MRFF-funded (Medical Research Future Fund) genomics program investigating the potential for the application of Whole Genome Sequencing in the breast cancer care pathway in Australia, ‘Q-IMPROvE’. She applies genomics and spatial transcriptomics methodologies to archival clinical samples to understand the differences between tumour types and their potential for treatment. Amy is passionate about clinical research, biobanking and precision oncology. In addition to her breast cancer research portfolio, she is on the steering committee for the Brisbane Breast Bank and the Scientific Advisory Board for Breast Cancer Trials.
