Joel Gaubicher studied chemistry and materials engineering in Paris. After obtaining a Ph.D. from the P&M Curie University of Paris, he joined the University of Waterloo, Canada, as a post-doctoral fellow with Prof. L.F. Nazar where he worked on phosphates and borates for Li ion battery. In 2001, he obtained a CNRS researcher position at the Institut des Matériaux Jean Rouxel in Nantes and developed research programs dealing with Li Metal Polymer, Li-ion, Na-ion, Li/S batteries and supercapacitors. His main interests deal with solid state electrochemistry of inorganic and organic materials through the investigation of synthesis and electrochemical mechanisms using operando physical characterizations. He was the recipient of a CNRS award for his research in 2013. More recently, he has been developing organic electroactive materials for aqueous based batteries as well as new strategy for prelithiation of lithium-ion capacitor.
