This talk will focus on the impact women are making in number theory. The first part will focus on some recent notable contributions to different branches within number theory. The second part of the talk will focus on efforts made to encourage women in this research area. We will pay special attention to one particularly successful venture: Women in Number Theory (WIN). They organize workshops and conferences, publish proceedings from resulting collaborations, connect community members at all stages of their careers and highlight contributions to number theory made by women. About the speaker: Allysa Lumley is a PhD. Candidate at York University studying analytic number theory under Dr. Lamzouri. She did her BSc and MSc. at the University of Lethbridge, Lethbridge AB. Part of her tenure at Lethbridge involved the design and organization of an outreach program called Fun With Math which aimed to introduce abstract concepts to students from grades 7-12. She is currently co-designing training sessions for the Math Kangaroo at York university and a founding member of the student chapter of the Association for Women in Mathematics. Last year Allysa implemented a Graduate Student seminar with the aim of providing a place for learning about presenting effectively and encouraging collaboration within the department.
