About Me

I am a clinical psychologist with expertise in treating men with prostate cancer and other genitourinary malignancies. As the psychological liaison to Memorial Sloan Kettering’s genitourinary and sexual medicine services, I provide short- and long-term counseling services to patients struggling with cancer-related issues. Men who are undergoing treatment for these diseases sometimes experience treatment-related sexual dysfunction, and I help them and their partners optimize intimacy before, during, and after treatment. I also work with the Center’s 65+ Program, providing psychological support for our patients who are 65 and older, and I co-facilitate a support group for patients dealing with the combined issues of cancer and aging.

Working with members of the symptom management, neurocognitive, and psychotherapy laboratories, I have focused my research on cancer’s impact on quality of life in prostate and geriatric cancer patients, and on developing new psychotherapy approaches for these groups. Some specific studies I have conducted include the impact of sexual dysfunction following cancer treatment; the cognitive effects of hormonal therapy on prostate cancer patients; distress in African-American men with prostate cancer; and developing assessment measures and psychotherapy specific to geriatric patients.

I am a member of many scientific and medical societies including Sexual Medicine Society of North American, Psycho-Oncology Association, and American Psychological Association, all organizations of specialists in my field. In addition, I am on the editorial board of and serve as statistical consultant for the Journal of Sexual Medicine and am a reviewer for various journals including the Journal of Urology and the Journal of Clinical Oncology. I am a member of Memorial Sloan Kettering’s Data Safety and Monitoring Committee.

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.
