Born in Buenos Aires, I received a BA from Harvard University, graduate degrees from the Universities of Geneva and Paris, and a Habilitation from the École des Hautes Études en Sciences Sociales. Before moving in 2018 to the field of medical anthropology, I worked as historian of the human sciences from the Renaissance to the present. I was Guggenheim Fellow, Athena Fellow of the Swiss National Science Foundation, Visiting Scholar at the American Academy in Rome and at Harvard University, Fellow at the Brocher Foundation, Visiting Professor in Buenos Aires, Paris, Rio de Janeiro, Mexico and Kyoto, and permanent investigator at the Max Planck Institute for the History of Science. I was elected to the Academia Europaea in 2017, and in 2021 received the Carlson Award "in recognition of extraordinary scholarship in the history of the human sciences."

How do values and the production and application of scientific knowledge interact in particular contexts to shape views and practices of the human? This has been the common question of my main research interests, which have long concerned the history of the mind/brain sciences from the early modern “sciences of the soul” to contemporary neurosciences. I keep working in those areas (see Lines of Research), but now also explore that question in the framework of medical anthropology and phenomenology. My main current project, which involves a network of researchers, patients and caregivers in Europe, the US and Japan, examines how the "disorders of consciousness" articulate with conceptions of personhood and forms of subjectivity. It focuses on the locked-in syndrome (known to the public through the film The Diving Bell and the Butterfly), a condition that leaves the mind intact, but the body almost entirely paralyzed.
