Dr Sandra Brosda

Research Fellow

Frazer Institute
Faculty of Medicine


Dr Sandra Brosda is a Research Fellow within the Surgical Oncology group led by Professor Andrew Barbour.

Dr Brosda was awarded a PhD in bioinformatics and cancer genetics from the University of Queensland in November 2020. Her research focused on biomarker discovery and intra-tumour heterogeneity and tumour evolution in oesophageal adenocarcinoma (OAC). In 2021, Dr Brosda was awarded a Cure Cancer Australia PdCCRS grant and an MSH project grant to further investigate tumour evolution to improve precision medicine in OAC.

She has been involved in research projects covering genetics, epigenetics, spatial transcriptomics, radiomics, ctDNA and quality of life assessments in the context of cancer. Overall, her research applies bioinformatics tools and approaches to cancer genomics to improve precision medicine and health outcomes for patients with melanoma, oesophago-gastric cancer and pancreatic cancer.
