Research Abstract

I am a clinical and translational investigator in the breast oncology center at Massachusetts General Hospital. The overall goal of my research is to develop novel approaches to the treatment of breast cancer. I am actively engaged in the design and conduct of scientifically driven clinical research studies, with a primary focus in triple negative breast cancer, as well as targeted therapies.
