Présentation

Fabien Giovannelli received his PhD degree in material sciences from Caen University in 2002, and is assistant professor at University of Tours since 2005. He is in charge of the research group “Functional oxides for energy efficiency” of GREMAN Laboratory. His research activitiy is focused on solid state chemistry, especially the synthesis and characterization of oxide materials with remarkable properties (thermoelectrics, piezoelectrics, superconductors, …). The objectives of the research undertaken are the understanding of all the mechanisms which control properties in oxides and their correlation with chemistry or manufacturing process for devices or application referred to energy transport, storage, conversion or saving.
