Raffaello holds a Chemical Engineering Diploma (2005) and a PhD degree in the field of physical organic chemistry (2010), both from the National Technical University of Athens, Greece. During his PhD, he specialized in the synthesis of solvatochromic probes and molecular switches. Later on, he moved to Marseille, France (September 2010–January 2013) working as a researcher at the Institute of Molecular Sciences, CNRS/Aix-Marseille University, in the field of water oxidation catalysts in the research group of Dr. Thierry Tron. Raffaello has subsequently moved to Uppsala University to join the group of Dr. Henrik Ottosson (2014) in which he worked as a PostDoc and later on as a researcher. His research interests revolve around physical organic and materials chemistry with an emphasis on the chemistry and photochemistry of graphene as well as polysaccharide chemistry. He is the author and co-author of 30 peer-reviewed scientific papers, three book chapters and has more than 35 contributions to international conference proceedings. Furthermore, Raffaello is an active referee of scientific peer-reviewed papers of world-class chemistry journals and he has acted repeatedly as a scientific expert evaluating international research grant proposals (including EU-grant applications). He has acted as the academic editor of a Book related to Dyes and Pigments and the Molecules (MDPI) issue: “Coupling Heterocyclic to Graphene Chemistry: Syntheses, Functionalizations, Interactions and Catalysis”. In his work at TdB Labs, Raffaello is particularly interested in polysaccharide fluorescent labeling and dye applications. Raffaello works currently as a senior research scientist at TdB Labs AB.
