Katrina Karkazis is a cultural anthropologist with extensive training in science and technology studies, gender studies, and empirical bioethics. Broadly, her work examines the interconnection of gender, embodiment, and sexuality within scientific and medical paradigms. She has used these lenses to analyze the medical treatment of intersex infants, which resulted in her book Fixing Sex: Intersex Medical Authority and Lived Experience (Duke University Press); “sex testing” of elite women athletes; and now, more broadly, research on the social and biological identities of testosterone (T) for the book T: The Unauthorized Biography (forthcoming with Harvard University Press), for which she was awarded fellowships from both the Guggenheim Foundation and the American Council of Learned Societies. Her writing has appeared in venues such as The New York Times, The Guardian, and Wired, and she has been interview for media around the world including Time, BuzzFeed, The Week, CNN, BBC, La Libération, the Toronto Star, Channel 4 (UK), Al Jazeera, and the Australian Broadcasting Corporation, among others.
