Current Research Interests

Dr. Moskowitz’s primary collaborations are with investigators in the cancer survivorship and radiology research communities. She also provides statistical support to the MSK Exercise Oncology Service. She is involved in studies researching issues pertinent to survivors of cancer, particularly survivors of pediatric cancers. Much of this work has been focused on the epidemiological study of late effects of treatment for pediatric cancers, but she has also served as the lead statistician for randomized intervention studies in this population. She works with radiology investigators on the design and analysis of a variety of studies assessing different imaging modalities, potential imaging biomarkers, and different imaging-based response metrics in cancer clinical trials. Her primary research interest focuses on identifying and evaluating different methods and modalities for identifying childhood cancer survivors at high risk of breast cancer.
