# Ioannis Liritzis

Ioannis Liritzis (Greek: Ιωάννης Λυριντζής; born 2 November 1953) is professor of physics in archaeology (archaeometry) and his field of specialization is the application of natural sciences to archaeology and cultural heritage. He studied physics at the University of Patras and continued at the University of Edinburgh, where he obtained his Ph.D. in 1980. Since then, he undertook postgraduate work at the University of Oxford, Université Bordeaux III, University of Edinburgh and the Academy of Athens.
Currently he is distinguished professor of archaeometry-Natural Sciences at the Henan University, Kaifeng, China Archived 2021-11-05 at the Wayback Machine and was professor in Archaeometry & Natural Sciences at the University of the Aegean and he directed and founded the Laboratory of Archaeometry (founded by him at 1999) and Lab of Environmental Archaeology. Director and initiator of the Masters course Applied Archaeological Sciences. In the past he served as Head of the Department of Mediterranean Studies at the University of the Aegean, Member of the Senate of University of the Aegean and Member of the Executive Committee of National Recognition of Foreign Academic Diplomas. His prior career includes the Greek Ministry of Culture for 5 years (1984–1989) and the Academy of Athens for 10 years (1989–1999).
He has made major contributions to several interdisciplinary research fields (geophysics, astronomy, planetology, paleomagnetism, paleoclimatology) and his work has been published in scientific journals such as Nature.

## Work

Liritzis is best known for the invention of two novel dating methods. The method for surface luminescence dating (introduced at 1994) where Liritzis extended the principles behind optical dating and thermoluminescence dating to include surfaces last seen by the sun before buried, of carved rock types from ancient monuments and artifacts, made of granite, basalt and sandstone and the obsidian hydration dating (introduced at 2002). This Liritzis' luminescence method has been improved and extended to other stone surfaces by other scientists.
Obsidian hydration dating established a new approach based on the surface saturation layer and the SIMS profile of hydrogen (SIMS-SS method). This SIMS-SS method has been improved by Liritzis and his PhD students to include criteria of the suitability of obsidian surfaces for dating.
Significant contributions in archaeoastronomy, in geophysics (archaeomagnetism, statistics in earthquakes, nuclear geophysics) are also worth mentioning.
Initiator of Delphi4Delphi International Project.
He has written over 300 original papers in internationally cited journals and 9 books (4 in English).
Many Greek and international magazines and newspapers have referred to his work, as has the Discovery Channel.
Liritzis has been elected as Membre Correspondant de l'Académie des Sciences, Arts et Belles-Lettres de Dijon and Member of the EASAEuropean Academy of Sciences and Arts, while since Jan 2021 is Dean of Class IV Natural Sciences in EASA https://euro-acad.eu/governance-legalacts. He was awarded the Prize of Academy of Athens for his Book Archaeometry: Dating Methods in Archaeology (1986). Recently he was awarded the Costa Navarino International Archeometry Award (2010) Issued by the University of Peloponesse. He is Visiting Distinguished Professor at Henan University (China) Visiting Scholar at the University of California San Diego. He has been awarded the title of Honorary Fellow from the Edinburgh University, Scotland; Honorary Professor at Rhodes University, Dept of Physics & Electronics, South Africa; Honorary & Gusr Professor at the Samara State Institute of Culture, Russia.
Liritzis is an editorial member in more than thirty International ICI Journals and is Editor-in-Chief of two.
He is the PI and initiator and coordinates the Aegean University Archaeological excavation project in Delphi & Kastrouli, regarding the Late Mycenaean site near Delphi, Greece.
The archaeology and history of Egypt (Egyptology) was first officially introduced in Greek university curricula in the Department of Mediterranean Studies (DMS) of the University of the Aegean. It was back in 1999 and the bright vision of Prof. Ioannis Liritzis approved by Temporary Academic Committee of the DMS, that Egyptology was inauguratedan as an academic discipline in Greek academia. Prof. Ioannis Liritzis established the Chair and in 2003, and managed the appointment of the first lecturer in Egyptology. Since 1998 official contacts between the Department of Mediterranean Studies essentially formed by Prof Liritzis, and the Egyptian authorities, were encouraged in research, fieldwork and education, through Greek and European funding. Through Prof Liritzis the Hellenic-Egyptian relationship in Egyptological studies in University curricula took off and has since then credited in plethora of publications and interactions. Prof. Liritzis has initiated many projects and Protocols of Collaboration (MOU) between Egyptian Universities and the University of the Aegean. The HERITAGE journal has published an Honorary Volume upon Liritzi's retirement, highlighting his major contributions and establishment of the Egyptology chair in Greece, and his collaboration with Egyptian researchers on the study of cultural heritage in Egypt, with three internationally renowned Guest Editors.
