My research centers on increasing the understanding of host-parasite ecology and evolution using evolutionary, molecular and genomic techniques to untangle the interaction between hosts and parasites. During my career I have used a range of model and semi-natural insect species in order to investigate questions around the evolution of resistance and susceptibility. I have a particular interest in the genetics of hosts and parasites and how the interactions of these can influence the outcome of a parasite challenge. Previous work with the European honey bee provided an interesting model to look at the influence of genetics on host – parasite coevolution; taking advantage of the distinct genetic make up of a social insect.

I am also interested in the role environment can play in shaping these interactions and how the background these occur in can often significantly influence the evolution of resistance or susceptibility. Whether this is the effect of resource availability, temperature or the role of co-infections, environmental influences often have a fundamental impact that cannot be ignored.

My current work in the group will use Drosophila to look at how parasites switch between host species and try to understand more about what factors influence the ability of a parasite to successfully infect a new host.
