Principal Research Interests

Dr. Walsh's current research is focused on developing organotypic 3D cancer models to define and validate the biological consequences of genomic variants of pancreatic cancer. Her research aims to understand the development of pancreatic cancer, to uncover markers for early detection and to identify those at high risk of pancreatic cancer.

To support these efforts, Dr. Walsh is funded by the Pancreatic Cancer Research Fund.

Other interests include understanding the tumour diversity caused by genomic alterations which contributes to cancer resistance to chemotherapy and molecular targeted therapies in breast and melanoma. Her lab uses genomic and functional NGS approaches to identify the mechanisms of genomic and immunological diversity to develop prognostic/predictive signatures and therapeutic strategies to overcome treatment resistance.
