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.
