Eric M Chang MD

Eric M. Chang, M.D. is an assistant professor in the Department of Radiation Medicine. Dr. Chang’s clinical work focuses on the use of palliative radiation therapy for patients with advanced cancer in both the inpatient and outpatient settings. He received his medical degree from the University of California, San Francisco and completed his residency training at the University of California, Los Angeles. His research interests include optimizing the delivery of palliative radiation therapy in effort to improve patient outcomes and minimize treatment burden. As a former healthcare consultant, Dr. Chang also has particular interest in economic analysis and health policy, with special focus on decision modeling and health state valuation.

  • Assessing the cost and cost-effectiveness of multiple treatment modalities in the palliation of bone and spine metastases
  • Estimating utility weights and patient preferences for cancer-related health states
  • Improving education in primary palliative care skills for radiation oncology residents
