Stephen Arthur Cook (born Dec. 14, 1939, Buffalo, N.Y., U.S.) is an American computer scientist and winner of the 1982 A.M. Turing Award, the highest honour in computer science, for his “advancement of our understanding of the complexity of computation in …

In computational complexity theory, the Cook–Levin theorem, also known as Cook's theorem, states that the Boolean satisfiability problem is NP-complete. That is, it is in NP, and any problem in NP can be reduced in polynomial time by a deterministic Turing machine to the Boolean satisfiability problem.

In 1985, Stephen Cook was promoted to the position of University Professor at the University of Toronto, and now holds the position of Distinguished University Professor in the Computer Science and Mathematics Departments.

Logic, Automata, and Computational Complexity: The Works of Stephen A. Cook …, 2023

May 27, 2020 · Stephen Cook is the foundational thinker behind this field-defining question. Cook was an undergraduate at the University of Michigan and earned his PhD in mathematics at Harvard in 1966; his dissertation, on the computational complexity of multiplication, improved an essential algorithm now known as Toom-Cook multiplication.

Stephen Cook is University Professor Emeritus of Computer Science at the University of Toronto. He is the 1982 Turing Award Winner and the 2012 winner of the NSERC Gerhard Herzberg Canada Gold Medal for Science and Engineering.

A visionary pianist, Dr. Cook expands the traditional piano recital with distinctive elements of artistic fusion. His innovative performance projects harmoniously merge music with visual arts, literature and film.
