My laboratory studies cancer stem cell biology and its implications for therapy. We are interested in developing a deeper molecular understanding of breast and lung cancer stem cells, including identifying pathways and genes important for survival and self-renewal. Additionally, we are developing novel biomarkers for measuring cancer stem cells in biopsy specimens or for detecting minute amounts of circulating tumor DNA. Clinically, I specialize in the treatment of lung cancer with a focus on stereotactic ablative radiation therapy to non-invasively cure early stage disease.
