Huge congratulations to PKU alumni Wang Hong and Deng Yu, recipients of the 2026 Fields Medal — mathematics’ highest honor! 🧮 Announced at the 2026 International Congress of Mathematicians (ICM) in Philadelphia, the pair are among four mathematicians worldwide to claim this prestigious prize, awarded every four years to outstanding scholars under 40. The awards are historic on several levels. —First time two mathematicians who completed undergraduate studies in mainland China win the Fields Medal in the same year. —Both joined Peking University as undergraduates in 2007. —Wang Hong becomes only the third female Fields Medalist ever, the first Chinese woman, and the first recipient with a bachelor’s degree from a mainland Chinese university. We are immensely proud of their extraordinary breakthroughs and lasting contributions to global mathematics.
