My interests are in diagnostic surgical pathology, in particular breast pathology. One of my goals is to use the results from immunohistochemical and genetic studies to refine the criteria for pathologic diagnosis. Most of my research activity is a part of a collaborative team of scientists and clinicians interested in the study of early breast cancer. We are studying the molecular and genetic pathways in breast cancer especially those related to lobular carcinoma. Another area of active research is in molecular markers and pathologic features in breast cancers following neoadjuvant chemotherapy.
