Ruochuan Liu is a Boya Distinguished Professor at Peking University, where he serves as Vice Dean of the School of Mathematical Sciences and holds a position at the Beijing International Center for Mathematical Research. He earned his bachelor's and master's degrees from Peking University and received his Ph.D. from the Massachusetts Institute of Technology in 2008, with a dissertation on the slope filtration of phi-modules over the Robba ring under the supervision of Kiran Sridhara Kedlaya. Following his doctorate, Liu completed postdoctoral work at the University of Michigan before joining the faculty at Peking University.
Liu specializes in number theory and arithmetic geometry, with research centered on p-adic aspects of these fields, including p-adic Hodge theory, p-adic automorphic forms, and the p-adic Langlands program. His contributions include foundational work on relative p-adic Hodge theory and studies of rigidity and the Riemann-Hilbert correspondence for p-adic local systems. He has authored numerous publications, such as collaborative papers in Inventiones Mathematicae, the Journal of the American Mathematical Society, and Duke Mathematical Journal. Liu has received several honors, including the 1999 International Mathematical Olympiad gold medal, the 2017 National Science Fund for Distinguished Young Scholars, the 2019 Tencent Xplorer Prize, the 2020 China Youth Science and Technology Award, and the 2024 Ramanujan Prize. He is a member of the Chinese Academy of Sciences and serves on editorial boards including those of the Peking Mathematical Journal, Acta Mathematica Sinica-English Series, and Nagoya Mathematical Journal.
Peking University's AI4Math team achieves a historic first by autonomously disproving the Anderson Conjecture using innovative AI agents Rethlas and Archon, with full Lean 4 verification.
