Hi, I'm Lionnel Mazuba from DRC. I'm engineer and I studied electronic's engineering at University of Kinshasa, where I got my bachelor's degree. I participated to the 2020's edition of IYMC challenge when I was student. I love so much to solve difficult mathematic's problems and I do my best to motivate others doing the same. So as an ambassador at IYMC organisation, I will reach that goal in the best way.
