Richard Peirce Brent is an Australian mathematician and computer scientist. As of August 2004 he is Professor of Computing Science at the University of Oxford. His research interests include number theory (in particular factorization), random number generators, computer architecture, and analysis of algorithms.
In 1973, he published a root-finding algorithm (an algorithm for solving equations numerically) which is now known as Brent's method.
In 1976 he and Eugene Salamin independently discovered the Salamin-Brent algorithm, used in high-precision calculation of pi.
He is descended from Hannah Ayscough, mother of Isaac Newton.
