The Bernoulli Center is proud to celebrate the Fields Medal of Maryna Viazovska, announced on July 5 at the International Congress of Mathematicians. Maryna has made profound contributions to the field of number theory, in particular with her resolution of the sphere packing problem in dimensions 8 and 24. Maryna is part of the executive committee of the Bernoulli Center and has played a key role in the re-birth of the center. A celebration event will be announced soon at the Bernoulli Center. Congratulations Maryna!
