Robert David Kleinberg (also referred to as Bobby Kleinberg) is an American theoretical computer scientist and professor of Computer Science at Cornell University.

Early life[edit]

Robert Kleinberg was one of the finalists at the 1989 Mathcounts.[1] He was a member of the 1991 and 1992 USA teams in the International Mathematical Olympiad, winning a silver medal and a gold medal, respectively.[2] He was also a Putnam Fellow in 1996.[3]

He graduated from Iroquois Central High School in Elma, NY, where he was valedictorian.

He is the younger brother of fellow Cornell computer scientist Jon Kleinberg.[4]


Robert Kleinberg is known for his research work on group theoretic algorithms for matrix multiplication, online learning, network coding and greedy embedding, social networks[5] and algorithmic game theory.


Robert Kleinberg received a B.A. in mathematics from Cornell University in 1997 and a Ph.D. in mathematics under Tom Leighton from MIT in 2005. He was a winner of the prestigious Hertz Fellowship, which supported him during his graduate studies.[6] In 2006, he joined the Department of Computer Science at Cornell University as an Assistant Professor. His work has been supported by an NSF Career Award,[7] a Microsoft Research New Faculty Fellowship, a Sloan Foundation Fellowship,[8] and a Google Research Grant.
