Woo S

is Professor and Chairman, Department of Radiation Oncology, Kosair Children's Hospital/Norton Healthcare Chair in Pediatric Oncology, School of Medicine, University of Louisville, Louisville, Kentucky. After 2 y of matriculation (college equivalent under the British system), Shiao was admitted to medical school (University of Malaya) for a 5 y program and skipped a year of pre-med. At the tender age of 23, Shiao graduated from medical school after completing a year of rotatory internship and 2 y of internal medicine. Dr. Woo then traveled to the United Kingdom in 1975 to take the internal medicine board and passed. He continued training and rotations at several pediatric hospitals and gained an interest in Pediatric Oncology after meeting Dr. Lucius Sinks at Georgetown University Medical Center in Washington, D.C. in 1978. Dr. Woo did a Fellowship under Dr. Sinks, his first mentor, at the Lombardi Cancer Center at Georgetown. Once he passed the American Board of Pediatrics and the sub-board of Pediatric Hematology/Oncology he became an Assistant Professor at Georgetown in 1980. In 1981 he went with Dr. Sinks to be an Assistant Professor of Pediatrics at the Tufts New England Medical Center in Boston.

By 1985, Dr. Woo had decided to be re-trained in radiation oncology and went to a residency program for the third time at Stanford University Medical Center. There he met his second mentor, Dr. Sarah Donaldson with whom he became lifelong friends. In 1988 he passed the American Board of Radiology (Radiation Oncology) and moved to Houston to become an Assistant Professor in Radiation Oncology at the MD Anderson Cancer Center. After only a year, Dr. Woo was elected by the residents to be the Residency Training Program Director and won a residency teaching award in 1990. In 1991, Dr. Woo lifted the Residency Program at Baylor College of Medicine out of probation, became one of the earliest investigators in the country in the field of IMRT and became recognized as an expert in treating childhood cancers as well as brain tumors. In 1996, he was promoted to Professor with Tenure at the Baylor College of Medicine; in 2001 he was named an Associate Chairman in the Department of Radiology; in 2004, he was recruited by Dr. James Cox back to MD Anderson to be the Professor and Section Chief of Pediatric/CNS Radiation Oncology and the medical Director of the Proton Therapy Center. In 2010, he was recruited to be the Chairman and Professor of the Department of Radiation Oncology at the University of Louisville, School of Medicine in Louisville, Kentucky.

Dr. Woo is an internationally recognized authority on the treatment of brain, spinal cord, and pediatric cancers. He is superbly trained, has obtained extensive clinical and research experience at the world-class MD Anderson Cancer Center of Houston, is widely published and serves on the Board of Directors of the Pediatric Radiation Oncology Society.

He is board certified in pediatrics, pediatric hematology-oncology, and radiation oncology. Dr. Woo's areas of clinical and research interest are tumors of the blood, bone, nervous system, and soft tissue in children and adults. He has published more than 140 articles in peer-reviewed journals and authored more than 20 book chapters.
