Currently he is distinguished professor of archaeometry-Natural Sciences at the Henan University, Kaifeng, China [1] 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.
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.
Obsidian hydration dating established a new approach based on the surface saturation layer and the SIMS profile of hydrogen (SIMS-SS method).
[15] This SIMS-SS method has been improved by Liritzis and his PhD students to include criteria of the suitability of obsidian surfaces for dating.
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.
