Description of Research Expertise

I have an academic focus limited to breast cancer. My research interests have been focused on shortening radiation courses by hypofractionation, intensity modulated radiation therapy (IMRT) with concurrent boost, proton beam radiation, and cardiac effects of radiation therapy/techniques to reduce cardiac dose in breast cancer. I have published over 100 peer-reviewed manuscripts, review articles and book chapters about breast cancer, radiation for early and advanced stage disease, radiation for intact breast and post-mastectomy indications, and radiation therapy techniques and side effects.
