Maryna Sergiivna Viazovska is a Ukrainian mathematician, born in Kyiv on 2 December 1984, known for her work in sphere packing and awarded the Fields Medal in 2022. She earned a doctorate (Dr. rer. nat.) from the University of Bonn in 2013 with a dissertation, Modular Functions and Special Cycles, supervised by Don Zagier and Werner Muller, and since January 2018 she has held the Chair of Number Theory at the Ecole Polytechnique Federale de Lausanne in Switzerland. In 2016 she solved the sphere packing problem in dimension 8, which quickly led to a solution in dimension 24 with collaborators, and she has also worked on spherical designs with Bondarenko and Radchenko. Her prizes include the Salem Prize, the Clay Research Award, the SASTRA Ramanujan Prize, the New Horizons Prize in Mathematics and the Fermat Prize.
