My research focuses on the molecular mechanisms of oncogenic activation of receptor tyrosine kinases and mechanisms for cell transformation using the Met, hepatocyte growth factor (HGF) and oncoprotein as a model. My research goals have now developed into a broader interest in understanding how multiple genetic alterations and epigenetic events synergize to promote tumorigenesis and progression in human breast cancer. This has involved both the generation of murine models of breast cancer involving the Met receptor as well as studies in human breast cancer with particular attention to changes within breast tumour associated stroma and how changes in the tumour microenvironment contributes to outcome.
