Animal life is in part made by their interactions with microbes. I'm interested in virtually everything to do with symbiont-host interactions, from mechanism through effects on populations to evolution of the symbiont/host. I am happiest working with insects, but symbionts are present in nearly all taxa, and thus we hope to discover more general truths. Also interested in the evolutionary ecology of sexually transmitted infections, meiotic drive, and more widely in co-evolutionary dynamics. I can be made interested in most of evolutionary biology. It is quite an interesting planet out there. Study systems: Happily work on different symbionts, and different hosts. Currently, Drosophila and Nasonia are favoured lab rats, bees, butterflies, midges and ladybirds favoured field systems. Bacteria: Arsenophonus, Spiroplasma, Rickettsia, Cardinium and Wolbachia.
