Okasha is a winner of Lakatos Award for his book Evolution and the Levels of Selection. From 2008 to 2011, he was Principal Investigator on a major AHRC-funded research project, ‘Evolution, Cooperation and Rationality’, in collaboration with Professor Ken Binmore, which led to a series of publications and an edited volume Evolution and Rationality.

From 2011 to 2016, Okasha was Principal Investigator on a research project entitled ‘Darwinism and the Theory of Rational Choice’, funded by a European Research Council Advanced Investigator Award.
