My general research interests focus on the ecology and evolution of host-parasite interactions. More specifically, I'm interested in the relationship between parasite dispersal/transmission dynamics, host adaptive responses, and the evolution of local adaptation and host-associated divergence. In a broad context, I consider how these factors may influence the evolution of biodiversity in spatially structured systems.

My primary research model involves different seabird species as hosts and two types of parasites, an ectoparasite (the seabird tick Ixodes uriae) and a microparasite (bacteria of the Borrelia burgdorferi s.l. complex). My research includes a combination of field observations and experimentation and the use of molecular markers analysed within a population genetic framework.
