Research Interests

Szabolcs Számadó is a theoretical biologist, his main research interest is honest signalling, which he  investigated with a range of tools including game theory, lab experiments and individual based modelling. His research includes a broad range of topics from the evolution of cooperation to the evolution of early human language. His latest interest is the role of reputation systems in the maintenance of cooperation and role of communication in the role maintenance of reputation. He published in top journals of the field (Proceedings of the National Academy of Sciences, Biological Reviews, Philosophical Transactions of the Royal Society B). He is the leading editor of a recent special issue on reputation systems ‘The language of cooperation: reputation and honest signalling’ published in the Philosophical Transactions of the Royal Society B.
