Christos Papadimitriou is a Greek-American theoretical computer scientist known for foundational contributions to computational complexity theory, algorithmic game theory, and the intersection of computation with economics and biology. He has explored philosophical implications of complexity, including how computational limits bear on questions in epistemology and the philosophy of mind.
Defined the complexity class PPAD and proved Nash equilibrium computation is PPAD-complete
Authored the influential textbook 'Computational Complexity'
Pioneered algorithmic game theory as a field
Developed computational perspectives on the brain and cognition
Elected to the National Academy of Sciences and recipient of the Knuth Prize and Gödel Prize
