  • PhD - Humboldt University, Berlin - 1992

Research Interests

Dr. Oesterreich's research is focused on endocrine resistance in breast cancer, including the analysis of aberrant genetic and epigenetic changes. She utilizes cell line models, mouse models, and clinical samples. More recently her group has begun to study the role of nuclear receptors including ER and PR in ovarian cancer development and progression.
