My research focuses on improving the treatment options for women with recurrent ovarian cancer. We are developing new agents that target blood vessels (angiogenesis) and regulate the immune system. Our goal is to develop more effective agents with fewer side effects.

In addition, I have a special interest in treating our older patients, and in studying the effects of aging on their tolerance to chemotherapy and surgery.

Clinical Trials

Research is integral to our mission at Memorial Sloan Kettering, and clinical trials help us discover better forms of patient care and treatment. For you, this could mean access to a new therapy or therapy combination. Click to see a list of the trials I’m currently leading.


Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
