Richard S. Sutton is a pioneering American-born Canadian computer scientist renowned as a foundational figure in reinforcement learning (RL), a cornerstone of modern artificial intelligence (AI). Often hailed as the “father of reinforcement learning,” his research has shaped the development of autonomous systems capable of learning through interaction with their environments.

Sutton earned his Ph.D. in computer science from the University of Massachusetts Amherst (1984), where his thesis on temporal credit assignment laid groundwork for RL. He co-authored the seminal textbook Reinforcement Learning: An Introduction, which remains a definitive resource. His innovations include temporal difference learning—a framework enabling agents to improve predictions over time—and the groundbreaking application of RL in TD-Gammon, a backgammon-playing program that rivaled human experts.

A professor at the University of Alberta since 2003, Sutton leads the Reinforcement Learning and Artificial Intelligence Laboratory and contributes to the Alberta Machine Intelligence Institute (Amii). He previously held roles at DeepMind (2014–2023) and industrial research labs (AT&T, GTE). His advocacy for human-like learning mechanisms in AI emphasizes reward-driven, trial-and-error paradigms over static datasets.

Honored as a Fellow of the Royal Society of Canada, AAAI, and ACM, Sutton received the ACM/AAAI Allen Newell Award (2019) for unifying computer science and RL. His work underpins breakthroughs like AlphaGo and advances in robotics, cementing RL as a critical AI discipline. Sutton continues to champion principles of “artificial intelligence as a science of agency,” inspiring generations to build adaptive, generalizable systems.
