The research in my laboratory is focused on how oncogenes alter decision making of the breast cancer cell and ultimately contribute to tumorigenesis. HER2-positive breast cancers represent a major subset of this cancer type. Overexpression of the HER2 receptor tyrosine kinase drives enhanced and constitutive signaling at the cell membrane resulting in activation of several proliferative and anti-apoptotic pathways. Targeted therapeutic strategies have been developed (lapatinib and trastuzumab) and are currently used in the clinic to treat patients that harbor amplifications of HER2.  Many patients develop resistance to these targeted therapeutics but the mechanisms of these resistance programs still remain incompletely understood. The major projects in the laboratory focus on determining the signal transduction pathways of HER2 in breast cancer and the mechanisms underlying resistance.

Another area of research in the laboratory is induction of metastasis. Carcinoma cells undergo dramatic changes that allow them to discontinue growth as epithelial cells in a solid tumor and switch to a more mesenchymal morphology that is compatible with migration and invasion-two features that are crucial for metastasis. My laboratory is focused on understanding the signaling and gene regulation required for this transition.
