Darren Obbard

I am interested in the molecular basis of adaptive evolution. By applying population-genetic approaches to host-parasite systems, I hope to understand how the selective pressure exerted by host-parasite interaction translates into adaptive change in the genome.

Most of my current work focuses on Drosophila and their viral pathogens, but I also have side interests in other pathogens and parasites of wild drosophila, and host-parasite coevolution in other insect systems, such as Anopheles mosquitoes, and nearly-insects, such as Daphnia.
