Theo Kyriazis (born 1981, Thessaloniki) is a Greek novelist and historian of technology. He studied archaeology at Aristotle University of Thessaloniki and earned an MSc in Science and Technology Studies from University College London, focusing on early mechanics in the Hellenistic world. After museum work in Piraeus and field surveys along the Nile Delta, he began writing fiction that blends rigorous research with speculative turns. He lives in Athens, where he teaches night classes on ancient engineering and sails a battered dinghy whenever the Meltemi cooperates.
