Janet Knight Horton
Adjunct Associate Professor in the Department of Radiation Oncology

My primary clinical and research focus revolves around women with breast cancer. Specifically, I am interested in studying breast cancer subtype specific (luminal, basal) radiation response in human breast tumors and utilizing that information to design biologically based radiotherapy trials.
