Hello from Helsinki! We are very pleased to be bringing you coverage direct from the 2022 International Congress of Mathematicians (ICM) – one of the highlights of the mathematical calendar. The ICM takes place every four years and it's usually the biggest maths conference of them all, attracting thousands of participants, and also sees the awards of some very prestigious prizes, including the famous Fields Medals.

This year's Congress is a little different – it is being held as a fully virtual event with only the prize ceremonies and lectures taking place in-person in Helsinki, Finland on 5 and 6 July. The rest of the schedule fascinating talks from across the spectrum of maths will take place online over the coming week.

In this podcast we announce the winners of all the prizes being announced today at the ICM and bring you an interview with one of them: Maryna Viazovska, who has won a Fields Medal for a ground-breaking result in the theory of sphere packings. Viazovska is only the second woman to receive a Fields Medal, following on from Maryam Mirzakhani who won it in 2014.

You can find out more about Viazovska's work in our short introduction or our more in-depth article.
