I’m a PhD student, supervised by Greg Hurst and Andy Fenton. My project is on the evolutionary ecology of the symbiosis between a fruit fly, Drosophila hydei, and the bacterium Spiroplasma. In this system, Spiroplasma protects D. hydei from the parasitoid wasp Leptopilina heterotoma. I am interested in how symbiont-mediated protection may be limited ecologically, and how it may interact with protection encoded by the fly’s own genome.
My previous work includes a period as a technician at Cambridge, working on Drosophila – sigma virus interactions. I also carried out two projects on Heliconius butterflies; one on spermatophore degradation at Cambridge, the other on male pheromones at the Smithsonian Tropical Research Institute in Panama.
