 After being a professor for five years in Geneva, I got a position of permanent professor at Institute of Institute of Scientific, where I arrived basically in 2016. So for me it was a funny story because I was raised in Bure-sur-Vivette. So I, from day one, knew the area and my mom was living like 200 meters from the institute and it was kind of coming back home. But at the same time it was also discovering a new place and kind of intimidating one because there is this whole history of the former professors of the institute that were really like extremely important members of French mathematics and French history of mathematics in the 20th century. So for me it was intimidating especially that I was coming with a new trend. I was the first professor in probability. So I had to make my probability part of the history of IHES. But it was very exciting for me to try to do that and to kind of bring something new to the institute. What the institute brings you as a researcher is very subtle. You see when you are in a standard university, the main core of the university is to teach students that remains its main duty. So it doesn't necessarily mean that you have a lot of teaching but the whole thing is organized around teaching. At IHES teaching is subsidiary to research. The institute is made in such a way that people should do research and should be in the best possible position to do research. And that changes everything because everything is organized around this target which is breaking new grounds in science and in my case in mathematics. And I felt it instantly. I could have full freedom. My days were free to really think. The environment is such that it makes you very creative because it's beautiful, it's peaceful. There is enough activity to still foster your imagination. So this was immediate and the two first years at the institute were probably the most productive years of my short career. And the other thing which is amazing about the institute is that it gathers many forces, many brains from all over the world. And for me it was very important because this is exactly the way I'm doing research. I want to be sharing my ideas with people. And here with the research program, the visiting program, which is a very big part of the DNA of the institute, I could bring many collaborators, new people I didn't have the occasion to discuss with yet. And to bring all these people together and in some sense to shake everything. I mean not literally obviously, but to shake all of these to create new things with it. And that was a fantastic feeling. And I'm very thankful to the institute for that and I hope that this part of the institute will be kept for years and years. Because in my case it really completely changed the level of energy I had for research.
