About Me

I am a clinical neuropsychologist with expertise in assessing the cognitive effects of cancer and its treatment. As the neuropsychology liaison to Memorial Sloan Kettering’s Breast Cancer Medicine Service, I provide assessment services to patients with cognitive problems.

Working with members of the Neurocognitive Research Laboratory, I study the cognitive and neurophysiologic aspects of cancer and its treatment with a focus on ameliorating cognitive problems. I am the principal investigator on a study of rehabilitation of cancer-related cognitive problems. I also study whether ethnic-minority women with breast cancer experience cognitive problems after chemotherapy as well as any electrophysiologic (EEG) changes that may occur.

I am a member of many scientific societies including the International Neuropsychological Society, the American Academy of Clinical Neuropsychology, the National Academy of Neuropsychology, and the American Psychological Association, all organizations of specialists in my field. Additionally, I am a member of the junior investigators in cancer survivorship group at Memorial Sloan Kettering.

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. Medicare and New York State Medicaid also provide benefits for care at MSK.
