Get to Know Me

I am a medical oncologist with a practice devoted to treating people with breast cancer.

I chose to focus on oncology because cancer is an enormous human problem and I wanted to help people who are affected by it. It has been my long-term desire to translate scientific discoveries into ways to treat disease and alleviate suffering.

My laboratory and clinical research both focus on developing new treatment strategies against breast cancers that become resistant to standard treatments. I research the molecular factors that play a role in resistance in order to identify targets that may lead to new treatments.

I am fortunate to work with an exceptional team of physicians and scientists who share my goal of eradicating breast cancer. Together, we are exploring several exciting ways of treating this disease.

Our research includes novel therapies that target the biological factors that make cancers grow. We are studying new inhibitors that block pathways that facilitate breast cancer growth or drug resistance. We are also investigating treatments that can deliver therapy specifically to cancer cells as well as antibody drug conjugates — hybrid drugs that make use of immunotherapy and chemotherapy — which will enable more targeted therapy.

What I Do at MSK

I'm a breast medical oncologist, which is a cancer doctor who specializes in breast cancer.
