In 2001, he began studying physics at the Faculty of Science. He had a clear goal in mind: "For a long time, my parents' house had neither water nor electricity. Not to mention a telephone or the Internet. But in Cameroon there are many fighters who want to make a difference, who are looking for and finding their place in the world." Marc is one of them. And so he did his bachelor's degree in physics and remembers: "My studies were mainly theory-based and consisted mainly of mathematics and abstract physics. Practical projects were a rarity. That's why, after completing my bachelor's degree in Yaoundé, I looked to build up knowledge based on practical experiences – and found the opportunity in Europe in 2005." Marc subsequently studied in Kaiserslautern and in Rouen. With his mechanical engineering diploma in his pocket, he spent the next few years working in the aerospace industry. "This had its own appeal for me. It was like reaching for the stars. But then the pandemic came and all planes were grounded. This was a sign for me to look for a new challenge."
