Dr. Emile HAYE studied material science in France and Sweden, and received a double-diploma from the European School of Material Engineering (EEIGM, France) and the Luleå University of Technology (LTU, Sweden), in 2013. From 2013 to 2016, he joined the Institut Jean Lamour (France), for a 3-years PhD on the anionic and cationic substitution of ABO3 perovskite thin films. In November 2016, he moved to Namur University (Belgium), for a post doc position, devoted to the physico-chemical characterization of new coatings for electrodes of proton exchange membrane fuel cells (PEMFC). Parallel to this topic, he develops new nanomaterials (thin films, nanoparticles) for applications in energy (supercapacitor, electro- & photocatalysts, magnetic membranes), using plasma processes. Since beginning of 2020, he is working on hard coating for cutting tools in dry machining, involving PVD-based processes.
