I'm an archaeologist working for the Foundation of the Hellenic World. My area of specialisation is the archaeology of the Late Bronze and Early Iron Age Greece. My Ph.D. thesis, entitled "The Archaeology of Early Iron Age Thessaly (ca. 1100-700 BC)", was completed at The University of Nottingham in 2002.
