Born in Buenos Aires, I received a BA from Harvard University, graduate degrees in psychology and history and philosophy of science from the Universities of Geneva and Paris, and a Habilitation from the École des Hautes Études en Sciences Sociales. After many years working on the history of the human sciences from the Renaissance to the present, I turned toward medical anthropology and phenomenology. I have been 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, and Visiting Professor in Buenos Aires, Paris, Rio de Janeiro, Mexico and Kyoto. I was until 2012 a permanent Research Scholar at the Max Planck Institute for the History of Science, Berlin. 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."
