Dr. O’Regan earned her Medical Degree from University College, Dublin, Ireland and completed her Internal Medicine residency at the Medical College of Wisconsin and her Hematology/Oncology fellowship at Northwestern University. She has received a multitude of awards and is ranked by Newsweek/Castle Connolly Medical as one of the top oncologists in the nation.
With a highly active research program focused on identifying mechanisms of resistance to breast cancer therapies and development of new therapies, O’Regan has been principal investigator for numerous grants and clinical trials. Her research group has made significant discoveries about the role of the PI3 Kinase-mTOR pathway in triple-negative breast cancer, showing that mTOR inhibition can sensitize breast cancer cells to upstream growth factor inhibitors. These discoveries resulted in a novel clinical trial for patients with metastatic breast cancer.
