I am a medical oncologist who specializes in breast cancer and early phase clinical trials. I study the molecular mechanisms that drive a patient’s cancer, with the goal of bringing new treatments with higher efficacy and improved tolerability to the clinic. As a clinical investigator, I believe that clinical trials offer hope to patients through the development of new treatment options. 

When caring for my patients, I strive to help them better understand their disease which can make people feel informed and empowered. I present often complex treatment options in the clearest possible way to offer the best therapy to each patient based on their needs. Every day I work with an amazing interdisciplinary team of nurses, surgeons, radiation oncologists, pathologists, radiologists, and biologists, all united with the common goal of delivering the best cancer care.
