[2] He was the recipient of the Prix Émile Benveniste awarded in 2010 by the Académie des Inscriptions et Belles-Lettres,[3] and became a member of the Institut Universitaire de France in 2013.

His main contributions concern the etymology, phonology and morphology of Proto-Indo-European and Indo-European languages, especially Latin and Greek.

His book on the Latin verbal system was favorably received, as shown by positive reviews by the American linguist Andrew Miles Byrd (University of Kentucky) in Kratylos[5],[N 1] and by the French linguist Jean-Paul Brachet (Paris-Sorbonne University) in the Bulletin de la Société de Linguistique de Paris.

[6] He was invited in 2015 by the French popular science journal La Recherche to represent the point of view of linguists on the Indo-European theory in a debate with the French archeologist Jean-Paul Demoule,[7] following the publication of a book in which the latter expresses skepticism about the Indo-European hypothesis.

A Czech translation of his first novel, L'Héritage de Glace, was published in 2012.
