Graham Brightwell is a British mathematician working in the field of discrete mathematics.

[1][2] Currently a professor at the London School of Economics, he has published nearly 100 papers in pure mathematics, including over a dozen with Béla Bollobás.

His research interests include random combinatorial structures; partially ordered sets; algorithms; random graphs; discrete mathematics and graph theory.

[3][4] (Bollobás supervised his PhD on "Linear Extensions of Partially Ordered Sets" at Cambridge, awarded 1988.

[7][8] He created the Brightwell Quotient, often used in Othello tournaments, to resolve ties.
