I study evolutionary and ecological processes mediated by parasitism in aquatic ecosystems. Parasites are ubiquitous and impose strong selection on their hosts to evolve resistance, while themselves being under strong selection to undermine host defenses. My research group aims to develop a better understanding of the interface between such host-parasite co-evolution and major ecological processes in the face of global environmental change.

Overall, our study shows that parasites are important for maintenance of host genetic diversity. See a commentary about our manuscript and IGB-news section.
