About Me

What I Do at MSK
  • Assistant Attending Physician
Get To Know Me

I am a medical oncologist with expertise in treating all stages of breast cancer in people of all ages, including young women who have unique concerns about fertility.

Over the years, I have learned how terrifying a breast cancer diagnosis can be for my patients and their families. My practice is focused on providing personalized, compassionate care that is based on the most up-to-date research, diagnostic tools, and therapies. My patients, along with a team of experts from many different departments across Memorial Sloan Kettering Cancer Center (MSK), are my most important partners in developing treatment plans.

Since college, I have never wavered in my choice of becoming a breast medical oncologist. A volunteer opportunity at a hospital boutique helping women with wigs and breast prostheses taught me that a patient’s experience with breast cancer encompasses so much more than just the biology of the disease. At the same time, some of my family members were affected by cancer, and I was fortunate to be exposed to leaders in the field. These experiences led me to work in a lab, where I studied the estrogen receptor. I was — and continue to be — fascinated by the science and ever-changing advances of breast cancer.

My research focuses on improving how we identify, prevent, and treat breast cancer that has spread to other parts of the body. I work to understand the environment in which cancer grows and how the immune system can play an important role in cancer development. I am also leading a clinical trial aimed at mobilizing the immune system to attack cancer early on in a patient’s diagnosis.

When patients first meet with me, they often feel as though the rug has been pulled right out from under them. One of the first things I ask is what they are most afraid of. Everyone is unique in their fears, so addressing those fears as well as needs and treatment goals helps us work together to create the most effective care plan.

At the end of each appointment, I hope each patient feels that they have been heard, understands their diagnosis, and is confident in the treatment plan we’ve created together. I also want them to know that they are not alone — we are here to help.

Beyond clinical care, I am passionate about communicating essential medical and scientific information to the public, particularly as it relates to women’s healthcare and wellness. I also have had the privilege of mentoring countless students throughout their academic and medical careers.

Outside of work, I love spending time with my husband and three young children. I also enjoy exercise such as running, yoga, dancing — you name it, I’ve tried it!
