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.

Mental health research on first responders in regional, rural and remote Australia
Dr Rikki Jones has been awarded to date a total of over $430,000 in research funding. She is currently leading four large national research teams focusing on rural health and sustainable rural health workforce (include mental health of first responders, sexual violence in rural Australia, virtual simulated nursing placements, and nursing students experience with online learning, connection and transitioning to practice).

Visceral pain and the gut-brain axis
Professor Stuart Brierley is Director of the Visceral Pain Research Group, Director of the Hopwood Centre for Neurobiology, and Theme co-Leader of Lifelong Health at the South Australian Health and Medical Research Institute (SAHMRI).
Prof Brierley is an international expert on the ‘gut-brain axis’ and chronic visceral pain mechanisms. Current investigations are on a individual cell type called the enterochromaffin cell, and it helps signal pain and anxiety from the gastrointestinal tract to the brain.
