Dr Lewis presenting a lecture in Japan
I am an evolutionary biologist interested in the evolutionary ecology of sex. Here at the University of Exeter (Cornwall Campus) I work as a post-doctoral researcher/research technician. My main role is research; I am currently interested in how genitalia evolve in Drosophila flies.

My research falls within the fields of evolutionary biology and behavioural ecology. I use arthropod model systems to investigate questions in sexual selection, sexual conflict and reproductive biology.
Sexual selection and genitalia
Genitalia are thought to be the fastest evolving morphological characters. While it is widely assumed that sexual selection is responsible for the rapid and divergent evolution of genitalia, there has been little empirical examination of this. I am currently investigating this topic in the fruit fly Drosophila simulans, in conjunction with David Hosken, Clarissa House, John Hunt, and David Hodgson (all Exeter).
Wolbachia and sexual selection
The endosymbiotic bacterium Wolbachia pipientis, is thought to infect up to 75% of terrestrial arthropods. Wolbachia is of importance to studies of sexual selection as the parasite manipulates host reproductive biology in order to increase its transmission, often with deleterious effects on the hosts fitness. In collaboration with Nina Wedell (Exeter), Steven Sait (Leeds) and Takahisa Miyatake (Okayama) I am investigating the effects of Wolbachia on the reproductive ecology of a number of butterfly and moth species.
Sexual selection and sexual conflict
Intralocus sexual conflict arises when traits shared by males and females are selected in opposite directions. Despite the importance of intralocus sexual conflict to the evolutionary process, few studies have conclusively demonstrated its operation. I am currently examining this in the Indian meal moth, Plodia interpunctella, in collaboration with Nina Wedell (Exeter) and John Hunt (Exeter).
