Connie is an experienced medical oncologist specialising in gastrointestinal, breast, gynaecological, and neuroendocrine cancers.

Connie is an experienced medical oncologist specialising in gastrointestinal, breast, gynaecological, and neuroendocrine cancers.

Connie is a member of several cooperative trials’ groups and a senior research fellow in the Bill Walsh Translational Cancer Research Laboratory at the University of Sydney in the Kolling Institute. Her research focuses on identifying prognostic and predictive biomarkers of inflammation in patients with colorectal, ovarian, and other cancers. These markers can be used to help guide decision-making in treatment, predict the likely disease course and potential patient responses to treatment. Connie is dedicated to the education and training of the next generation of clinicians. She is a  conjoint senior lecturer at the University of Sydney and Co-Director of Training in the Department of Medical Oncology at Royal North Shore Hospital. Connie puts you, the patient, at the centre of her care by ensuring you are empowered with the right information to be part of the decision-making process for your treatment. As a patient in Connie’s care, you can be sure you are being treatment by an expert medical oncologist, working as part of a dedicated multidisciplinary team.

Research interests

Connie is passionate about research, because she believes it has the power to significantly improve people’s lives and outcomes. She encourages her patients to consider joining clinical trials where appropriate. Connie’s own research has been published extensively, and she actively applies her research insights to the care of her patients. In 2021, Connie was co-author of an article about the innovative use of scalp cooling technologies to reduce hair loss for women undergoing chemotherapy for breast cancer.
