Ms. Melessanaki Kristalia
Technical Scientist

Kristalia (Alina) Melessanaki holds an arts conservation degree from the School of Conservation of Antiquities and Works of Art, University of Western Attica, Athens (1999) and has been a staff member at IESL-FORTH, since 1998. She has been actively involved in all research activities of the PhoHS group with emphasis on applications related to the use of laser methodologies for cleaning and analysis of 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 (icons, paintings, contemporary artworks etc.) as well as evaluation and monitoring of the cleaning interventions using spectroscopic and imaging techniques.

Over the years she has participated in major national and EU projects at IESL-FORTH including IPERION-HS, E-RIHS, HELLAS-CH, POLITIEA-I and II, HERACLES, IPERION-CH, CHARISMA, ATHENA, PROMET, LASTOR, MOBILART.
