Yifeng Liu

Yifeng Liu (刘一峰) is a Chinese mathematician specializing in algebraic number theory, automorphic forms, and arithmetic geometry, who left his professorship at Yale University to join Zhejiang University's Institute for Advanced Study in Mathematics (IASM) around 2021.

Liu earned his BS from Peking University in 2007 and his PhD from Columbia University in 2012 under advisor Shou-Wu Zhang. He held a C.L.E. Moore Instructorship at MIT (2012-2015), was an assistant professor at Northwestern University (2015-2018), then an associate professor and professor at Yale University (2018-2021) before joining IASM.

Liu's research addresses the arithmetic aspect of the Langlands program. He received a Sloan Research Fellowship in 2017 and shared the 2018 SASTRA Ramanujan Prize with Jack Thorne, one of the most prestigious honors for mathematicians under 32. In 2025, he and collaborators from the AIM SQuaRE program received the Alexanderson Award from the American Institute of Mathematics for their work on the geometry of Shimura varieties and arithmetic applications to L-functions. He joined a string of senior mathematicians recruited to IASM from top American universities, following geometer Ruan Yongbin (2021) and preceding Fields Medal contender Song Sun (2024).
