About Me

I am a medical oncologist who specializes in caring for people with breast cancer and head and neck cancer. I provide high-quality care through both standard and emerging treatments based on each patient’s unique needs. I see patients at Memorial Sloan Kettering Commack, on Long Island, and also help patients enroll in clinical trials at both MSK Commack and MSK’s Manhattan locations.

I work with a team of experts from different areas including surgeons, medical and radiation oncologists, nurses, pharmacists, social workers, nutritionists, and physical therapists. Collaborating with my colleagues helps me to provide my patients with the most effective treatments for their individual needs. It also allows me to help my patients manage any symptoms or side effects that may arise by connecting them with our wonderful support services.  

In my research, I focus on developing new therapies for breast cancer using a patient-centered approach that is based on breast cancer biology and newly identified drug targets.
