Shiri Artstein-Avidan (Hebrew: שירי ארטשטיין-אבידן; born 28 September 1978) is an Israeli mathematician who in 2015 won the Erdős Prize.

She specializes in convex geometry and asymptotic geometric analysis, and is a professor of mathematics at Tel Aviv University.

She graduated summa cum laude from Tel Aviv University in 2000, with a bachelor's degree in mathematics,[1] and completed her PhD at Tel Aviv University in 2004 under the supervision of Vitali Milman, with a dissertation on Entropy Methods.

[5] In 2008 she won the Krill Prize for Excellence in Scientific Research, from the Wolf Foundation.

[7] The award cited her "solution of Shannon's long standing problem on monotonicity of entropy (with K. Ball, F. Barthe and A. Naor), profound and unexpected development of the concept of duality, Legendre and Fourier transform from axiomatic viewpoint (with V. Milman) and discovery of an astonishing link between Mahler's conjecture in convexity theory and an isoperimetric-type inequality involving symplectic capacities (with R. Karasev and Y.
