Simon N. Powell

Simon N. Powell (born February 1955) is a British cancer researcher and radiation oncologist residing in New York City.

Powell was born on February 13, 1955, in Manchester, England. Powell received the Bachelor of Medicine, Bachelor of Surgery in 1981 from the University of London and went on to complete his Ph.D. there in 1991, holding residencies at Whittington Hospital and Hammersmith Hospital in London^[1] and a fellowship at the Royal Marsden Hospital before being recruited and settling in America.^[2][3]

Powell held a fellowship at Harvard Medical School in 1991,^[4] becoming an instructor in 1992, and associate professor of radiation oncology in 1998. He then became clinical director of the Gillette Center for Women's Cancers,^[5] co-leader of the Harvard Breast Cancer Research Program, and leader of the DNA Repair/Radiation Biology Program.^[4] From 2004 to 2008 he served as professor and head of Radiation therapy/radiation oncology at the Washington University School of Medicine in St. Louis.^[3][5]

In 2008, Powell moved to New York to join Memorial Sloan Kettering Cancer Center and become the Chair of the Department of Radiation Oncology in Memorial Hospital^[6] with a joint appointment in Sloan Kettering Institute's Molecular Biology Program.^[7] He was also appointed to the faculties of the Gerstner Sloan Kettering Graduate School of Biomedical Science^[8] and Weill Cornell Graduate School of Medical Sciences.^[9][10] He also holds the Enid A. Haupt Chair in Radiation Oncology at the Center.^[11] His career has centered on understanding DNA repair alterations in cancer and how they can be used for the basis of selective cancer therapies. His clinical expertise is in the treatment of breast cancer.^[2]
