Broadly interested in the histories of modern medicine, biomedical sciences and public health, my research has focused in particular on transformations in the experience and management of pregnancy and childbirth since the late nineteenth century. My writing has also explored the visual and material and cultures of science and medicine, including anatomical images and educational films. I am currently working on a book that examines the history of folic acid as a technology of pregnancy, with its implications beyond reproduction for the globalization of biomedical knowledge, the management of risk and the role of consumer activism in shaping public health policy.
