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.

December - feels like a Xmas present:) - our long-term field study is finally out, published in Evolution. We analysed genotype dynamics in a Daphnia population sampled across 13 years (over 240 time points). We found that periods of higher infection are correlated with higher genotype turnover in the host population. Outside of epidemics, turnover of host genotypes is slowed down. Overall, our study shows that parasites are important for maintenance of host genetic diversity. See a commentary about our manuscript.
