Ms. Melessanaki Kristalia

Kristalia Melessanaki is an art’s conservator, graduated from the School of Conservation of Antiquities and Works of Art in Athens (1999). She has been a staff member of IESL-FORTH since 1998, involved in several research projects and applications related to the use of laser techniques for cleaning and analysis of cultural heritage objects. Her research interests include laser spectroscopic techniques (LIF and LIBS) for the analysis and characterization of archaeological objects and works of art, laser cleaning applications on artworks (Byzantine icons, easel paintings, contemporary artworks etc.) as well as evaluation and monitoring of the cleaning interventions using spectroscopic and imaging techniques.

He has been actively participated in several National and  EU projects, realted to Cultural Heritage namely "HERACLES", "IPERION-CH", “CHARISMA”, "ATHENA",  "PROMET" , "LASTOR", "MOBiLART", "LATECA" etc.
