Ukrainian maths professor Maryna Viazovska, who on Tuesday won the top mathematics prize, the Fields Medal, said her life “changed forever” when Russia invaded her home country.
The 37-year-old’s parents and sisters were living in Ukraine’s capital, Kyiv, when the war began in February.
“I could not think of anything else, including mathematics,” she in a video as she received the prize at a ceremony in Helsinki.
Her sisters along with her young nephew and niece were evacuated from Kyiv and are now staying with her in Switzerland, where she works at the Ecole Polytechnique Federale de Lausanne.
Viazovska and three other mathematicians received the Fields Medal, dubbed the Nobel prize in maths, in Helsinki after the ceremony was moved from Saint Petersburg to the Finnish capital in response to Moscow’s war.
