Eileen Connolly, M.D., Ph.D. is Assistant Professor of Radiation Oncology at New York Presbyterian/Columbia University Medical Center. She is a board-certified radiation oncologist who cares for patients with all types of cancer but specializes in the treatment of breast and pediatric malignancies with radiation therapy. Dr. Connolly has published various articles in her field, including several related to breast cancer. In addition to her breast research she participates in a number of Children’s Oncology Group (COG) protocols for the treatment of pediatric malignancies and works closely with the Pediatric Oncology group at Morgan Stanley Children's Hospital of New York-Presbyterian/Columbia University Medical Center.

Dr. Connolly received her M.D./Ph.D. degree, internal medicine and radiation oncology training at New York University School of Medicine, where she was Chief Resident of Radiation Oncology. During her residency training, she received both the 2010 Varian Medical Systems/RSNA Research Resident Grant and the 2010 ASTRO Residents/Fellows in Radiation Oncology Award. In addition, Dr. Connolly was trained in Gamma Knife Radiosurgery at the University of Pittsburgh Medical Center - Center for Image-Guided Neurosurgery, pioneers in the field of stereotactic radiosurgery for brain cancers and malformations.

Besides her clinical duties Dr. Connolly is the director of a translational research laboratory in the Center for Radiological Research (CRR) in which she pursues her research interests in understanding the mechanisms of radiation resistance of cancer. Specifically, her work focuses on the PI3K/Akt pathway with a goal of developing targeted agents that may be used as radiation sensitizers to reduce the risk of local recurrence. For her research, she has received the 2012 Radiological Society of North America (RSNA) Research Seed grant, and a 2012 Irving Institute/Clinical Trials Office Pilot Award.
