We celebrate the run-up to the European Congress of Mathematics (ECM) with Fields Medallist Maryna Viazovska who previously won a prestigious EMS prize at the ECM.

Viazovska is only the second woman to receive a Fields Medal, for her ground-breaking proof to a problem we're all familiar with.

Maryna Viazovska has won one of this year's Fields Medals for a ground-breaking result in the theory of sphere packings.
