Research Interests

Dr. Malmgren's main research focus is on breast cancer. She has been conducting registry-based studies for the last 19 years that include leukemia incidence post-breast cancer treatment, triple-negative disease, metastatic breast cancer and characteristics of mammography detected breast cancer. Her expertise is in survival analysis and risk modeling. In addition, she conducts validation analysis using SEER data. Her research has included studies of leukemia incidence post breast cancer diagnosis using SEER/Medicare data and comparison of regional metastatic breast cancer survival over time. She is currently focused on metastatic breast cancer, exceptional survivors and evaluation of lead time bias related to breast cancer detection method.

Outside of breast cancer and clinical oncology research, she is involved in health care quality improvement studies including surgical comparative effectiveness studies and randomized clinical trial set up and analysis.
