I teach Roman history, the so-called auxiliary sciences (epigraphy, numismatics and literature) and advanced Latin courses for the Centre d'études classiques (detached 50%) and the Department of History. My main field of research is the history of the Roman Empire, in particular the Late Empire period (192-565 AD). My research activities fall into three categories.

1. My main interest lies in the history of the administration and political system of the Roman Empire, especially the reorganization of its provinces in the Late Empire period.
2. A second focus of my research has to do with themes of cultural history and mentalities during the Late Empire. This is a direct outgrowth of my main interest, because I have often had to use literary sources in studying the administrative history of the Empire, and in such cases I have had to first understand the cultural background in order to grasp the opinions expressed regarding administrative changes. My interest in this research has particularly to do with Latin and Greek authors who expressed their opinions on politics, although they are not classified in the "historiography" category, such as the sermons by Church Fathers Ambrose of Milan and John Chrysostom, the panegyrics of Themistius, and epic poetry.
3. The third aspect is dedicated to the history of science in antiquity and the historiographical themes related to science, i.e. to famous figures of antiquity (Constantine the Great) or the writings of ancient authors (Livy and Ammianus Marcellinus).

My MA and PhD students have worked on the first two fields of research, but not exclusively. Regardless of the research topic, I consider a good knowledge of ancient languages (Latin and Greek), modern languages (English, German, Italian and Spanish, depending on the subject) and the so-called auxiliary sciences (literature, epigraphy and numismatics) to be key success factors for any kind of advanced research.
