About Me


PhD, Clinical Psychology, State University of New York at Albany


University of Mississippi Medical Center; Veterans Administration Medical Center (Jackson, Mississippi)

I am a behavioral psychologist with a special interest in the cognitive effects of cancer treatments. My clinical interests have focused on cognitive-behavioral interventions designed to improve symptom management (e.g., cognitive problems, pain, sleep disorders) and to reduce stress associated with cancer and cancer treatments. In addition, I am the psychological liaison to the Neurology Service and to the Brain Tumor Center.

I currently lead the Neurocognitive Research Laboratory, which I was recruited to Memorial Sloan Kettering Cancer Center to develop. The lab examines cognitive changes associated with cancer (e.g., brain tumors) and cancer treatments (e.g., chemotherapy and radiation therapy). My research has focused on investigating cognitive changes associated with adjuvant chemotherapy for the treatment of breast cancer. My other research interests include cancer pain management and palliative care.

I am a member of many scientific and medical societies. Currently, I am a member of the Quality of Life and the Symptom Control Subcommittees of the Cancer and Leukemia Group B Committees.
