Ioannis Karatasios is a research officer in the Institute of Materials Science of the National Centre for Scientific Research Demokritos, since March 2007, with an initial employment background in the Hellenic Ministry of Culture. He owns a BSc in Archaeological and Architectural Conservation from the Technological Educational Institute of Athens, Greece (1998) and a PhD in Conservation Science from De Montfort University, UK (2005), on the development of lime-based mortars with enhanced durability against sulphates.

He works on the characterisation of archaeological and building materials and he is specializing in research on mortars technology and the pathology of stone monuments. His research activities also include the study of archaeological glass, ceramics and wall paintings.

Ioannis Karatasios is collaborating with the department of Conservation of Antiquities and Works of Art, TEI of Athens in many research projects and he teaches Conservation of Stone and Archaeological objects.

He is a member of the European Committee for Standardisation CEN/TC 346/ WG2 ‘Materials constituting cultural property’ and task leader for the WI ‘Characterisation of Stone’, a member of the Hellenic Committee for Standardisation ELOT/ TC 96, a member of the International Institute for Conservation (IIC), the Hellenic Society of Archaeometry (HSA) and a Chartered Surveyor for archaeological and historical monuments. 

Research Interests

Ioannis Karatasios currently is working on three fronts:

  • Technology of archaeological mortars and development of new conservation mortars.
  • Pathology and consolidation of architectural monuments and decorative surfaces.
  • Weathering and technology of archaeological glass and ceramics.
