1. Avi Wigderson was named the winner of the A.M. Turing Award, widely considered one of the top honors in computer science, for his foundational contributions to the theory of computation. Professor Wigderson’s work has touched nearly every area of the field. His colleagues, collaborators, and mentees say he consistently finds unexpected bridges between disparate areas. And his work on randomness and computation, starting in the 1990s, revealed deep connections between mathematics and computer science that underlie today’s investigations. Madhu Sudan, a computer scientist at Harvard University who won the 2002 Rolf Nevanlinna Prize (now called the Abacus Prize), said Wigderson’s influence on the field is impossible to miss. “It’s very hard to work in any space in computer science without actually intersecting with Avi’s work,” Sudan said. “And everywhere, you find very deep insights.” (Sources: quantamagazine.org, math.ias.edu/avi/book, harvard.edu)
