Hello, my name is Nicolas, I am 39 years old and the audience I am most used to is that of preparatory classes for the grandes écoles, for mathematics courses in general. However, I also have experience in preparing students from the second to the third year of the bachelor's degree due to the large number of hours of lessons I have given as well as the many students I have followed. My teaching method consists of clarifying the course first, making sure that each definition and theorem is well understood. We then discuss the basic exercises and techniques, and finally, if the course followed is demanding, tackle more complicated exercises or even competition subjects. I arrived in Brussels in 2021 for a position at the University and am eager to share my interest in science with as many people as possible. My background and my research interests also allow me to intervene in physical sciences or computer science.
