 Hello everyone, I would like to welcome you to this 2021 Friends of IHS Gala. This is the very first time our Gala is being held in a hybrid format, and I am glad that you are sharing this special moment with us. Let me start by thanking our supporters for this event. The Simons Foundation, the Institute's key sponsor, BNP Paribas, or Premier Sponsor, or Gala shares Vincent de la Pietra and Barbara Amundsen, I would also like to thank David and Florence Foucon. Special thanks also goes out to Benjamin Servonnet and Kavita Shah, as well as our sponsors, DLA Piper, NG, Ardion and Facebook. Thank you to the Friends of IHS, our partner institution in the U.S., for organizing this event and for supporting the unique model of our research institute. We are here today to address the underrepresentation of women in fundamental science. This is a crucial issue for all of us. As long as women remain a minority in mathematics and physics, we miss out on half of our intellect and knowledge in these domains. In September, we have the pleasure of welcoming Laure-Saint-Rémond, the first female permanent professor at IHS ever. She is an extraordinary mathematician and I'm delighted that she joined the institute. But it's also a little bit bittersweet to see that it took us so long. Tonight, it's an occasion for us to reflect on what can be done to improve the situation. In fact, IHS has organized three events dedicated to that topic. In September, we hosted an event with Martin Yotto, founder and president of the Women Initiative Foundation, who helped us identify the lessons that could be learned from businesses who support women. In early October, we hosted a panel discussion promoting women in mathematics with experts from the Association of Women in Mathematics and European Women in Mathematics. Tonight, we intend to celebrate women at IHS, but more generally women in science, tech, engineering and finance, all domains which remain male-dominated. Through this series of events, we intend to implement actions which will foster a better representation of women at the institute. Therefore, all fans raised today will go toward increasing inclusion and gender diversity at IHS. We thank you in advance for your support. And since I mentioned Laura Saint-Raymond, you may be eager to know a bit more about her work. She specializes in partial differential equations. Her contributions are very important and profound. Alongside some of her prominent colleagues, Laura has made fundamental contributions to one of the mathematical problems proposed by David Ilbert, which has not yet been solved. The following video will tell you more about it.
