I am a medical oncologist and translational researcher whose focus is on providing the best care possible to people with breast cancer. My dual role in the clinical setting and the laboratory allows me to work with my patients to develop more-effective, less-toxic therapies. I strongly believe that this is how we will change the future of cancer care.

The ability to use a patient’s own immune system as a form of cancer treatment — immunotherapy — is revolutionizing how we attack many cancers. My goal is to bring these advances to people with breast cancer, a disease for which we are still discovering immunotherapy’s full potential. To this end, I am a member of the Center for Cell Engineering and the Parker Institute for Cancer Immunotherapy at Memorial Sloan Kettering, where I am involved in both clinical trials and laboratory research that aim to bring the most promising immunotherapies to our patients. My expertise is in cellular therapy and genetic engineering, immune-stimulating antibodies and hormones (also called cytokines), and cancer vaccines.

Like many others, my family has been impacted by cancer. I have firsthand experience with how devastating a cancer diagnosis can be, and this guides every interaction I have with my patients and their families. It’s my goal to provide them with a full understanding of the nature of their disease, the treatment options available, and the evidence that supports these options. I believe it’s critical to present what can be an overwhelming amount of information and medical jargon in a way that makes sense.

In addition to empowering my patients with knowledge and understanding, I also want to empower them by providing clear ways of accessing and communicating with me and other members of their care team throughout their treatment and follow-up care. I never want my patients to feel isolated or alone. This communication and collaboration helps us focus on making people feel physically better and confident that they are receiving a treatment plan tailored to their individual needs and goals.
