Hello, my name is Nicolas, I am 35 years old and the public to which I am the most accustomed is that of preparatory classes for the grandes écoles, for mathematics lessons in general. However, I also have experience in preparing students from the second to the third year of the license because of the large number of hours of lessons that I have given as well as the many students 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 have just arrived in Brussels as part of a job at the University and look forward to communicating my interest in science to as many people as possible. My background and my research interests also allow me to intervene in physical sciences or computer science.
