Yannis Kalliontzis has studied Greek history, archaeology and epigraphy in Athens, Paris and Neuchâtel. His dissertation on the history and epigraphy of Hellenistic Boiotia will be published as a monograph by the French School at Athens in 2020. He has worked on the epigraphy of various regions, but his many focus is Boiotia. In collaboration with K. Hallof, N. Papazarkadas and J. Curbera, he is currently preparing a new edition of the corpus of the inscriptions of Thebes and its hinterland for the Inscriptiones Graecae series of the Berlin Academy. He is also collaborating with G. Biard on the history and archaeology of the sanctuary of the Muses in the Valley of the Muses in Askra (Boiotia) under the auspices of the Ecole française d’Athènes. While at CHS he is planning to finish work on the philological and epigraphical testimonia on the Valley of the Muses.
