Angela N. H. Creager is the Thomas M. Siebel Professor in the History of Science at Princeton University, where she teaches and advises students in the Department of History. She has written two books: The Life of a Virus: Tobacco Mosaic Virus as an Experimental Model, 1930–1965 (2002), which shows how a virus that attacks tobacco plants came to play a central role in the development of virology and molecular biology; and Life Atomic: A History of Radioisotopes in Science and Medicine (2013), which traces how and why artificial radioisotopes were taken up by biologists and physicians, and examines the consequences for knowledge and radiation exposure. She is the co-editor of five volumes, the most recent being Risk on the Table: Food Production, Health, and the Environment with Jean-Paul Gaudillière (2021). Her new book project, “Making Mutations Matter,” examines science and regulation in the 1960s through the 1980s, focusing attention on how researchers conceptualized and developed techniques for detecting environmental carcinogens.
