Sophie Roux is Professor of the History and Philosophy of Science at the École Normale Supérieure, Paris, where she was a director of the graduate program in Humanities and Social Sciences and where she is currently director of the research team La République des savoirs (CNRS-Collège de France-ENS). After her PhD, she held positions at the MPIWG (Berlin), at the Centre Alexandre-Koyré (Paris) and at the University of Grenoble. Sophie’s main research interest is in the history of early modern science and early modern philosophy, and more specifically in the history of Cartesianism and anti-Cartesianism in France. She also wrote papers concerned with philosophy of science (e.g., on thought experiments or on mathematization) and with history of philosophy of science (e.g., on Pierre Duhem, on Louis Couturat or on the so-called French historical epistemology). During the year 2021–22 she is a fellow of the Wissenschaftskolleg zu Berlin, where she is working on a project entitled “The Pineal Gland, Comets, and Subtle Matter: The Natural Objects with Which Cartesians Tried to Conquer France (1637–1691).”
