Academic Career and Research Areas

Clarimma Sessa earned a degree in Science and Technologies for Conservation and Restoration of Cultural Heritage at the University of Perugia, Italy in 2008. She holds a Master in Advanced Chemistry and received her PhD in Chemistry from the University of Barcelona, Spain in 2014. She achieved a Post-doc Alexander-von-Humboldt Fellowship in 2016 for the implementation and optimization of a practical analytical protocol for the characterization of organic colorants on artworks by means of Surface-Enhanced Raman Spectroscopy at the Doerner Institut, Bavarian State Painting Collections (Munich) in collaboration with the Raman and SEM group of the Chair of Analytical Chemistry and Water Chemistry of the Technical University Munich. Her scientific interests are mainly focused on the evaluation and application of non-invasive analytical techniques for the study of artworks. She is currently working as Conservation Scientist at the Chair of Conservation-Restoration, Art Technology and Conservation Science of the Technical University Munich, where at present she is creating a new mobile analytical infrastructure for Cultural Heritage studies.
