 So hello everybody. Welcome to this event at IHES, celebrating the International Day of Women Mathematicians. I'm very happy to be here and welcome also to the people online because I know there are quite a few of you. So it will be my pleasure to lead you to through tonight's event. So I guess I have to present myself first. So my name is Berthier Folon. I am French. I am a PhD student at the École Normale Superheure and at Inéria-Paris under the supervision of Francis Bach and Homo Tsimsegli. And I work on theoretical aspects of statistical learning. And this is my first year, so it's all fresh. And I'm very happy to be here tonight because, well, for reasons I will talk about now I guess. So when I first started, I don't know, liking math, I was in high school and I was in a small town in the countryside of France and, you know, it was still average. Like there were still a lot of female in my class and a lot of female teachers. But then as the years went on it all went downhill, I would say. So first two years of undergrad, I mean then undergrad and then masters and now PhD and it's the statistics are not getting better. And it was only last year actually in my second years of master that I had my first class, like math class taught by a female professor. And that had like a good impact on me. I was like, oh, there are people that I know that are in the same field as me and that are women. And I think those little pushes, those little, like, people you see, they do make a big impact of you because there are so few of them sometimes and that can be disheartening. So I'm happy that we're here today to celebrate women mathematics because I think that's through like these little events and these little pushes that you can motivate people to keep on and women to keep on, most specifically. And for example, last year I was I was awarded a prize, a prize for undergrad, not for graduate students research projects, but you had you had to be a woman. And this prize was also called Maria Mirzakini. And it was awarded by the Foundation Mathematics Jacques Adamard, who's also like co-organizes this event. And it like, you know, I was working on this project and I wanted to get it published and I was a bit stressed and, you know, still a graduate student. So is it going to be good enough? And then till I get the price and get this little push to keep going and then got accepted last month. So I'm happy. And so I think those the things are really important. And the question, the first question I guess for today is why do we celebrate today and not any other day? So if we're celebrating women mathematicians tonight, it's because it's the follow up of an initiative that was launched in 2018 after the during the world meeting of women in mathematics, which was just before the last International Congress of Mathematicians in the Rio. And during that time, like May 12 was decided to be the day of the International Day of Women Mathematicians because it is Miriam Mirzakini's birthday. And I guess no one needs introduction, but I will still give it. So Miriam Mirzakini was an Iranian mathematician and she got the Fields Medal in 2014 for her outstanding work in dynamics and geometry. And she's the only woman who ever got it. And she's, I think, a big inspiration to every woman mathematician out there. And sadly she passed away in 2017, quite young, and celebrating May 12th at her birthday. And as the International Day of Women in Mathematics is a way to honor her and all the other women in mathematics, but also like hopefully all of the one who will come next and who will join us in this great math adventure. So tonight we're going to listen to two women who have expressed themselves on the topic of this huge gender imbalance that there is in mathematics, science and research more in general. So first mathematician Indira Chatterjee. And then photographer Marie-Elaine Leunis. So if you can come here and then I can introduce you. So after obtaining her PhD at ETH Zurich in Switzerland, you moved to the US to do a postdoc at Cornell. And then you became an assistant and associate professor at Ohio State. And then you came back to France, I mean not back, but you came to France at Université d'Orléans as a professor in 2007. You then spent a year as a visiting professor in New Delhi and then in 2013. And then you moved to Nice, where you still work as a professor at Université du Côte d'Azur and your research interests, our Geometric Group Theory. And you have shared your reflections on the gender gap in mathematics that you have experienced yourself and your fellow mathematicians in a few articles that you can find online that are published in La Gazette des Mathématiciens in the newsletter d'Aplie. So tonight you will talk to us about institutionale bias explained by the mathematicians. So the floor is yours. Go now.
