Civil engineer graduated for 5 years in Mechanics and Energetics (French school), I worked for 4 years then as an engineer in various companies in Liège. My studies and my professional experiences provided me with a solid foundation in theory in Mathematics, Physics and more generally in science. I can give courses in this area at all school levels. During my studies, I also gave courses in Mathematics and Physics to two high school teenagers, for a whole year, who progressed a lot.
