About William Hwang, MD, PhD

Dr. Hwang is a radiation oncologist at the Massachusetts General Hospital Cancer Center, Instructor of Radiation Oncology at Harvard Medical School, and Andrew L. Warshaw, MD Institute for Pancreatic Cancer Research Fellow. As a physician-scientist, he specializes in the treatment of gastrointestinal cancers and his research program is focused on elucidating the interactions between pancreatic cancer cells and their microenvironment at high resolution using single-cell omics and multiplexed imaging techniques. Dr. Hwang is particularly interested in studying the synergy between cancer cells and nerves, an important mechanism of recurrence, metastatic spread, and pain in pancreatic cancer, as well as the pathways by which radiotherapy reprograms the tumor immune microenvironment and how these changes may be harnessed to improve immunotherapeutic strategies. His research has been recognized with the Seidman Prize for Outstanding Senior Medical Student Thesis, MGH Clinical Research Award, William Shipley Research Award, and the Conquer Cancer Foundation/American Society of Clinical Oncology Young Investigator Award.

Dr. Hwang holds bachelor's degrees in Biomedical Engineering, Electrical & Computer Engineering, and Physics from Duke University, where he was an Angier B. Duke Scholar.

He earned his MD (summa cum laude) at Harvard Medical School as a Paul and Daisy Soros Fellow and PhD in Biophysics at Harvard University.
