She became Professor of the History of Science and Affiliated Professor of Earth and Planetary Sciences at Harvard University in 2013, after 15 years as Professor of History and Science Studies at the University of California, San Diego. She has worked on studies of geophysics, environmental issues such as global warming, and the history of science.
