Samuel J. Tazzyman


I’m a researcher at University College London’s Centre for Mathematics and Physics in the Life Sciences and Experimental Biology (CoMPLEX). I am currently employed as a Research Associate on the 2020 Science programme, a collaborative effort involving the University of Oxford and Microsoft Research, Cambridge, in addition to UCL.

My research is concerned with using mathematical modelling to investigate evolutionary hypotheses, so far general to do with sexual selection and mating strategies in animals.

My current research interests are threefold. Firstly, I am interested in sperm competition, particularly how it affects sperm depletion and the phenotype-linked fertility hypothesis. Secondly, I am interested in the evolution of secondary sexual ornamentation in varying environments. Thirdly, I am also involved in modelling the sexual selection strategy of Saccharomyces yeast. More generally I am interested in modelling any topics connected with evolution and sex. In the future I would like to branch out and use modelling techniques in other areas of the natural sciences.

As well as the academic elements of being a researcher, I am interested in communicating science to the wider general public through various public engagement activities. The details of some of these activities can be found here.

Before my current position I was funded by the EPSRC’s PhD plus programme during 2012, having completed my PhD, entitled “Modelling the Evolution and Consequences of Mate Choice”, in December 2011. Prior to becoming an evolutionary biologist, I studied Mathematics at undergraduate level at the University of Warwick.
