Pauline Koetschet, née en 1980, est agrégée de philosophie (2005) et ancienne élève de l’École Normale Supérieure (Ulm, 2001). Ses recherches portent principalement sur l’articulation de la médecine et de la philosophie au début de la philosophie arabe médiévale, en particulier au IXe siècle et au tournant du Xe siècle.
Après un doctorat soutenu en 2011 sur "La mélancolie chez Abû Bakr al-Râzî, entre médecine et philosophie", sous la direction de Marwan Rashed (Université Paris-Sorbonne) et Peter E. Pormann (Université de Warwick), elle passe deux ans au Caire à l’Institut français d’archéologie orientale. Chargée de recherche au CNRS depuis 2014, elle rejoint d’abord l’équipe Textes et documents de la Méditerranée antique et médiévale à Aix-en-Provence (2014-2019), avant de rejoindre l’Institut français du Proche-Orient en tant que directrice du département des études arabes, médiévales et modernes. Elle rejoint le centre Léon Robin en janvier 2025.
Ses travaux explorent les points de contact entre la médecine et la philosophie, en particulier dans l’œuvre d’Abû Bakr al-Râzî : les relations entre l’âme et le corps, la conception de la matière, l’interprétation de phénomènes physiques tels que l’attraction, la théorie de la sensation et de la vision, les liens entre physique et métaphysique. Parmi ces points de contact, elle s’est intéressée à en particulier à l’épistémologie, et à la manière dont la méthodologie médicale s’est insérée dans des discussions autour de notions telles que le signe, l’induction, la preuve. Elle a publié une édition critique et une traduction des Doutes sur Galien d’Abû Bakr al-Râzî (De Gruyter, 2019) et travaille aujourd’hui avec Iktimal Rajab à la publication de la Solution aux Doutes sur Galien d’Abu al-‘Alâ' ibn Zuhr.
Ses recherches accordent également une place importante au Galien arabe. Ainsi, avec Matyáš Havrda, elle a publié très récemment l’ouvrage Galen, On Demonstration. Reconstruction of a lost treatise from Greek and Arabic Sources (De Gruyter, 2025). Avec Aileen Das et Mark Schiefsky, elle se prépare également à publier Galen: Writings on Plato’s Timaeus.

Giulia Scalas, born in Rome in 1989, has been a research fellow since October 2024 at the CNRS, within the Centre de recherches sur la pensée antique – Léon Robin (UMR 8061).
After studying philosophy at the Università di Roma – Sapienza, she defended her PhD in 2019 at the University of Lille. She has worked as a temporary lecturer and researcher at the Université Paris Nanterre and at the Faculty of Medicine of the University of Lille, before holding postdoctoral positions within the “Medicine and Philosophy” program at the Léon Robin Centre as well as in the IUF project Galenus Verbatim (UMR Orient & Méditerranée – Sorbonne Université).
Her research focuses mainly on atomist doctrines, and particularly on Epicurean philosophy. She is the author of a monograph, La théorie épicurienne du vivant, based on her dissertation, published in 2023 by Classiques Garnier (Les Anciens et les Modernes – Études de Philosophie), which examines the Epicurean conception of living beings in dialogue with certain philosophers and physicians (Democritus and Leucippus, the Hippocratic doctors, Aristotle and Theophrastus).
Alongside this work, she has conducted critical and textual studies on several complex testimonies traditionally regarded — notably according to Usener — as constituting the Epicurean corpus. The analysis of Lucretius’ work has played a central role in this context. She has also explored the ways in which Epicureanism continued to shape the thought of modern philosophers (Locke, Kant) and even contemporary ones (J. Bennet).
At present, she devotes special attention to Epicurus’ vast and fragmentary treatise On Nature (Peri Physeos), known mainly through papyrological sources still being uncovered, focusing on its elaboration and its transmission within the Hellenistic and post-Hellenistic Kepos. In connection with her research on the concept of “mechanism” as related to Epicurean physiology, she is working in particular on the revision of the edition of Book XIV of the Peri Physeos, together with its French translation and commentary. She is also part of a working group dedicated to the translation and commentary of Book XXVIII of the Peri Physeos.

Since 2018, much of his research has focused on the study of palimpsest and damaged manuscripts using advanced imaging techniques, notably multispectral imaging. Following several research projects in this field, funded by Sorbonne Université and the City of Paris, he is the Principal Investigator of the ERC PALAI project starting in January 2026. This work has led to the rediscovery of Claudius Ptolemy's lost treatise on his Meteoroscope, fragments of Hipparchus' Star Catalogue, and fragments of a Latin introduction to Platonic philosophy (often referred to as the "New Apuleius"). He is currently pursuing his explorations in various collections containing palimpsest and damaged manuscripts, notably at the Bibliothèque nationale de France and in various libraries preserving Northern Italian manuscripts.
His work lies at the intersection of the history of philosophy and the history of science. A common denominator is the desire to renew the interpretation of Greco-Latin sources by taking into account not only cuneiform texts, but also other ancient and medieval languages of learning. With W. Furley, he has published the monograph Reading the Liver. Papyrological Texts on Ancient Greek Extispicy (Tübingen, 2015), and with A. Schwab the collective volume Le travail du savoir. Philosophie, sciences exactes et sciences appliquées dans l'Antiquité (Trier, 2015), and he updated M. Federspiel's translation, Aristote. Traité du ciel (Paris, 2017).
He has also published the only known fragments of ancient commentaries on Aristotle's Sophistic Refutations, which he discovered in a treatise by the humanist Agostino Nifo (Forgotten Ancient Commentaries on Aristotle’s Sophistical Refutations, Berlin, 2023), and the first full edition, translation and commentary of the fragments of Eudoxus of Cnidus (Eudoxe de Cnide, Témoignages et fragments, Paris, 2024). He is also the author of articles and reviews available here and here in open access, mainly on the interpretation of fragments relating to the history of science, cosmology and philosophy in antiquity.
