Claire Isabel Webb directs the Berggruen Institute’s Future Humans program. She earned her Ph.D. from MIT’s History, Anthropology, and Science, Technology, and Society (HASTS) program in 2020. An internship at the Search for Extraterrestrial Intelligence (SETI) Institute in 2008 sparked the topic of Webb’s dissertation: Technologies of Perception: Searches for Life Beyond Earth. Informed by her ongoing work with the SETI group Breakthrough Listen at U.C. Berkeley, Webb’s book project historically and ethnographically tracks how scientists have investigated extraterrestrial life forms—both microbes and beings—since the Space Age.
