Research Interests

My research relates to clinicopathologic correlations, prognostic factors and biomarkers in gynecologic, breast, and soft tissue pathology. I serve as the local reference pathologist for Gynecologic Oncology Group and other trials, triaging biospecimens for translational research as well as study qualification. In a collaboration with Ting Wang (Genetics), I am investigating the genetic and epigenetic basis of endometrial cancer and of uterine carcinosarcoma, a variant of endometrial cancer that accounts for a disproportionate share of mortality. Using laser capture microdissection, we have separated the two components of the tumor (carcinomatous and sarcomatous) and identified distinctive epigenetic differences between them. Another concern related to carcinosarcoma is that it is not currently possible to predict which patients will be long-term survivors. We will determine whether testing for specific combinations of mutations and epimutations in the tumor can predict those who will survive or those who will respond to chemotherapy. In a separate set of projects, I am interested in studying the clinical implementation of next-generation sequencing to delineate its role in cancer diagnosis, prognosis and prediction.
