Avi Wigderson has helped to lead theoretical computer science and mathematics to a greater understanding of the role that randomness plays on complexity, as well as its limitations. Drawn to computer science at the suggestion of his parents—who thought the field might provide a more practical outlet for his love of mathematics—Avi Wigderson, the 2023 ACM A.M. Turing Award recipient, has made lasting contributions to the theory of computational complexity. Wigderson’s voracious intellectual curio...
