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.

Anaemia guidelines updated after 50 years
Professor Sant-Rayn Pasricha is the Acting Deputy Director at the Walter Eliza Hall Institute of Medical Research in Melbourne, Australia. He is also a clinical haematologist at the Royal Melbourne Hospital and the Peter MacCallum Cancer Centre. From a young age, Prof Pasricha dreamed of becoming a doctor and found joy in learning about the human body and how to care for patients. After completing medical school, he developed a passion for working in low and middle-income countries, which led him to spend time working in East Timor, India, and Central Australia with First Nations communities.

CASE STUDY Next Generation Condom Contraception
Eudaemon Technologies, an early-stage medtech company with a focus on sexual reproductive health, is developing a hydrogel condom to address the need for a better feeling, next generation condom, with the potential to improve user experience and address issues with traditional latex condoms.
“Over 1 million STI’s being diagnosed every day and up to 120 million unplanned pregnancies every year result in a $60 billion health burden across the globe”, says Co-Founder and Executive Director of Operations, Dr Simon Cook.
Formed in 2018, the company focuses on developing tough hydrogels as an alternative to address issues with odour, colour, and taste commonly associated with latex condoms. This technology can be loaded with small molecule drugs for flavours or anti-STI compounds, and was developed in response to a grant from the Bill and Melinda Gates Foundation to address unplanned pregnancies and STIs.
