Yifeng Liu (born July 19, 1985 in Shanghai, China) is a Chinese professor of mathematics at Zhejiang University specializing in number theory, automorphic forms and arithmetic geometry.

[2][3] Liu returned to China in 2021 to join Zheijiang University became a full professor of mathematics.

[1] Liu has made important contributions to arithmetic geometry and number theory.

His contributions span a wide spectrum of topics such as arithmetic theta lifts and derivatives of L-functions, the Gan–Gross–Prasad conjecture and its arithmetic counterpart, the Beilinson–Bloch–Kato conjecture, the geometric Langlands program, the p-adic Waldspurger theorem, and the study of étale cohomology on Artin stacks.

[2] He was awarded the 2018 SASTRA Ramanujan Prize for his contributions to the field of mathematics.
