Trained in psychiatry and history of science, David Jones is the Ackerman Professor of the Culture of Medicine at Harvard University. His research has focused on the causes and meanings of health inequalities (Rationalizing Epidemics: Meanings and Uses of American Indian Mortality since 1600) and the history of decision making in cardiac therapeutics (Broken Hearts: The Tangled History of Cardiac Care). He is currently at work on four other histories, of the evolution of coronary artery surgery, of heart disease and cardiac therapeutics in India, of the threat of air pollution to health in India, and of the history of air pollution research in the United States. His teaching at Harvard College and Harvard Medical School explores the history of medicine, medical ethics, and social medicine.
