Our laboratory conducts research focused on the elucidation of the molecular mechanisms that control the intercellular signaling governing organogenesis and cancer development. We are particularly interested in the study of cell-to-cell communication pathways in breast and lung development, and in defining how deregulation of these signals leads to neoplastic conversion. We use highly innovative mouse genetic approaches to define the cell-specific roles of the Notch pathway in breast and lung biology by modulating Notch signaling activity in specific cell populations of the mammary and lung epithelia. Our laboratory is also interested in defining the cellular origins of the distinct subtypes of breast and lung cancers, and in establishing the role of Notch signaling as a downstream mediator of nuclear receptor signaling in the breast epithelium, particularly in mammary gland stem cells. Our laboratory has a strong interest in developing of novel technologies for lineage analysis of normal and cancer stem cells, and in the identification of pharmacologically targetable pathways to treat breast and lung cancers.
