Thomas Duffy - Professor of Internal Medicine

Thomas P. Duffy, MD

Professor Emeritus of Medicine (Hematology), Yale School of Medicine

Thomas Duffy is Professor of Internal Medicine (Hematology), Yale School of Medicine.  His interests in medical ethics center on the doctor-patient relationship and its hierarchy of moral principles. His specific focus is on the tensions between opposing or non-complementary principles (truth-telling/hope; autonomy/paternalism) in the physician’s life. This tension represents the focus of the art of the practice of medicine. His practical interest in ethics surrounds courses in clinical ethics for medical residents and medical students – material that evolves out of the problem cases that constitute their clinical experience. He is a member of the Yale-New Haven Hospital Ethics Committee, participating in ethics consultations and helping to develop position papers in medical endd of life ethics. He is also the chairperson of the Interdisciplinary Center for Bioethics “End-of-Life Issues” study group.
