As a native New Yorker, he received his undergraduate degree in Physics at Columbia University. He went to medical school at Harvard and also received a Master of Science degree in Biophysics from Harvard University. He received his M.D. degree from Harvard Medical School, jointly with the Massachusetts Institute of Technology, as part of the Health Sciences and Technology (HST) program. He returned to New York City and the Columbia University Medical Center for his residency training in Radiation Oncology, where he also served as a chief resident. He joined the Weill Cornell Medical Center as faculty, where he serves as attending physician for Breast Oncology and for Gastrointestinal Oncology. His most recent awards include the Faculty Educator of the Year Award from the Weill Cornell New York-Presbyterian Residency Program, a RSNA Roentgen Research Award, an ASCO Research Travel Award, and a NCCN Travel Grant.Dr. Ng was recently appointed the Chair of the Radiation Oncology Section of New York Roentgen Society, the only scientific group that congregates radiation oncologists in the New York Metropolitan area and is comprised of leaders in the fields of diagnostic radiology and radiation oncology. He also currently serves as a Program Committee member for the American Association for Cancer Research (AACR), serves on the Economics Committee of the American College of Radiation Oncology (ACRO), and is an active Program Committee member of the New York Metropolitan Breast Cancer Group.Areas of Specialization:Breast Cancer, Gastrointestinal Cancers, Breast Intraoperative Radiotherapy, Breast Balloon Brachytherapy, Pancreatic Cancer, Sarcoma, Stereotactic Body Radiotherapy (SBRT).Research:Dr. Ng’s research is focused on developing novel radiation techniques that can reduce treatment side effects and improve outcomes. One area of particular focus is developing partial breast radiotherapy techniques to treat less breast tissue with less radiation to reduce side effects and to shorten treatment times.Another research interest is advancing radiotherapy technologies to treat pancreatic cancer. He is currently writing a textbook review on Gastrointestinal and Hepatobiliary Radiation Therapy and working on a review on minimizing malignancy risks after radiation therapy.He is also actively involved in the development of new drugs and agents to use with radiotherapy to improve cure rates for breast cancer and gastrointestinal cancers. Presently, his group is collaborating with others in developing skin products to decrease skin side effects from breast radiotherapy.
