Research Bio
Ruixiang Zhang is is a mathematician whose research investigates harmonic analysis, analytic number theory, additive combinatorics and partial differential equations. He mainly works in Fourier restriction problems. Zhang’s work often combine methods from Fourier analysis, geometry and combinatorics to address central questions about oscillatory integrals and exponential sums. His scholarship has advanced the interface of analysis and number theory, with applications to classical problems in mathematics.
He is an Assistant Professor of Mathematics at UC Berkeley. Zhang has received the Sloan Research Fellowship, NSF CAREER Award, and the 2023 SASTRA Ramanujan Prize. He is a sectional speaker at the International Congress of Mathematics in 2026. At Berkeley, he teaches courses at various levels in analysis and algebra, mentoring graduate students in harmonic analysis and related fields.
