Yifeng Liu, professor of the Institute for Advanced Study in Mathematics, has been named one of the recipients of the 2025 Alexanderson Award, alongside his collaborators—Raphaël Beuzart-Plessis (Université d'Aix-Marseille), Yichao Tian (Chinese Academy of Sciences), Liang Xiao (Peking University), Wei Zhang (Massachusetts Institute of Technology), and Xinwen Zhu (Stanford University).

Established by the American Institute of Mathematics (AIM), the Alexanderson Award is presented annually to recognize outstanding scientific research resulting from AIM SQuaREs research projects over the preceding three years. The award is formally presented during the Joint Mathematics Meetings (JMM) the following January.

This year's award is conferred upon the research team for the AIM SQuaRE project “Geometry of Shimura Varieties and Arithmetic Applications to L-Functions,” in recognition of two seminal papers:

“Isolation of cuspidal spectrum, with application to the Gan-Gross-Prasad conjecture” by Beuzart-Plessis, Liu, Zhang, and Zhu, published in the Annals in 2021; and

“On the Beilinson-Bloch-Kato conjecture for Rankin-Selberg motives” by Liu, Tian, Xiao, Zhang, and Zhu, published in Inventiones in 2022.

As a highlight of the 2026 Joint Mathematics Meetings, the awards ceremony was held on the evening of January 5 at the Walter E. Washington Convention Center in Washington, D.C. Additionally, Professor Yifeng Liu, representing the team, delivered the Alexanderson Award Lecture titled From periods of modular forms to arithmetic geometry on the morning of January 6.
