Research Interest


My research focuses on determining the molecular and cellular mechanisms that are engaged by cancer cells that allow them to grow in these different metastatic microenvironments. The most deadly aspect of breast cancer is the spread or metastasis of cancer cells from the primary tumor to sites throughout the body. When breast cancer cells metastasize, they primarily form metastases in specific organs and tissues, including the bones, lungs, liver and brain. We employ mouse models of breast cancer metastasis to identify and functionally test the role of specific proteins in the metastatic process. My group collaborates with clinicians, surgeons and pathologists to clinically validate targets but also to use clinical material from patients with metastatic cancer to identify novel targets that can be further explored in the pre-clinical animal models established in our lab.

Research Foci


  • defining molecular mechanisms that drive the migration and invasion of cancer cells
  • examining the determinants of organ specificity in breast cancer metastasis
  • defining the contribution of tumor-derived and microenvironmental influences of metastatic cancer

Keywords
