Research Interests

I am interested in the evolution of signaling systems, principally those associated with sexual selection and the handicap principle. During my PhD and subsequent post-doc at University College London I used experiments on stalk-eyed flies to investigate how genetic and environmental factors interact to produce sexual ornaments (exaggerated male eyespan) that reflect the quality of their bearer. I have also explored the causes of variation in individual mate preferences, and examined the consequences of such variation on sexual selection. For more details see http://www.ucl.ac.uk/%7Eucbhkof/stalkie/People/sam.html

Here in Lausanne, I am examining the importance sex ratios and sex chromosomes in conservation biology from a mainly theoretical perspective. The sex ratio has received relatively little attention in this field, despite its importance in evolutionary biology. I am exploring the effect of deviations from sexual unity on population growth and evolution, and evaluating the consequences of environmentally induced sex change in systems with predominately genetic methods of sex determination.
