Alexandru Mardale is Professor of Romanian language and linguistics, the head of Romanian Studies at INALCO (Paris) since 2022, and a member of the lab Structure et Dynamique des Langues (SeDyL) at the Centre National de la Recherche Scientifique. He completed his PhD at the University Denis Diderot (Paris 7) in 2007 and his Habilitation in 2020. His main research topics concern the morphosyntax of Romanian from both a Romance and Balkan perspective. He has published extensively on differential object marking (DOM, a specific type of argument marking) in Old and Modern Romanian, from a Romance comparative perspective (with Spanish, Sardinian, Sicilian, French dialects). In his more recent studies, he focuses on this phenomenon in the language of heritage speakers of Romanian from France, but also on some other phenomena (e.g. the acquisition of relative clauses, case, pronominal clitics or anaphora resolution).
