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 90 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. I am co-chair of the Radiation Oncology breast committee with responsibility for the written board examination for the American Board of Radiology. I am a member of the NRG breast cancer committee local-regional subcommittee.
