Edwin Choy

Assistant Professor


Dr. Edwin Choy was raised in Los Angeles, CA and graduated from Yale College in 1993 with a B.S. in Molecular Biophysics and Biochemistry. He received his MD and PhD in 2000 from New York University School of Medicine and then completed residency training at Massachusetts General Hospital. This was followed by a fellowship in medical oncology at the Dana Farber Cancer Institute, Brigham and Women’s Hospital, and Massachusetts General Hospital. He then completed a postdoctoral research fellowship at the Broad Institute of MIT and Harvard. Upon completion of his fellowship, Dr. Choy joined the faculty in the Division of Hematology Oncology at Massachusetts General Hospital. Dr. Choy has spent more than 25 years studying the genetics and biology of cancer, and he is currently the Director of Sarcoma Research at the MGH Cancer Center. His clinical practice and research focuses exclusively in the medical management of patients with sarcomas, gastrointestinal stromal tumors, chordomas, giant cell tumors, and desmoid tumors. He works closely with a team of world class surgical, orthopedic, and radiation oncologists as well as connective tissue pathologists and radiologists to provide optimal care for his patients. He directs a clinical trials program at the Dana Farber / Harvard Cancer Center that includes over a dozen active phase I-III clinical trials. He also maintains an active scientific research program that investigates diverse areas of sarcoma therapy, ranging from the use of nanotechnology and other translational research tools aimed at developing new targeted therapies for treating cancers to preclinical studies using cell lines and animal models to better understand the molecular basis of sarcoma biology. Dr. Choy is currently Assistant Professor at Harvard Medical School.
