Director, Center for Outcomes Research & Evaluation (CORE)

 Research Interests

  • Uncertainty in health care
  • Risk Communication
  • Shared decision making
Dr. Han is the Director of CORE, Associate Professor of Medicine at Tufts University School of Medicine, and a behavioral and health services researcher and board-certified general internist and palliative care physician.  He received an M.D. from the New York University School of Medicine, and an M.A. in Bioethics and an M.P.H. from the University of Pittsburgh. He completed Internal Medicine residency training at UCLA, and a fellowship in cancer prevention and control at the National Cancer Institute.

Dr. Han’s research program focuses on understanding and improving the communication and management of uncertainty in health care, and his work bridges the disciplines of health services and behavioral research. His specific research projects focus on risk communication, shared decision making, and predictive modeling, and examine clinical problems in cancer care, genomic medicine, and palliative and end-of-life care. Dr. Han currently serves as Principal Investigator of the Maine Lung Cancer Coalition, a statewide lung cancer prevention and screening program funded by the Bristol-Myers Squibb Foundation, the Maine Cancer Foundation, and the Maine Economic Improvement Fund. He also leads MMC’s collaboration on the Maine Cancer Genomics Initiative, a statewide program of The Jackson Laboratory, aimed at advancing cancer genomic testing in oncology care. Dr. Han has authored over 100 papers in the peer-reviewed medical literature, and is actively involved in initiatives to promote shared decision making and to teach risk communication skills to medical students and physicians.
