Evolutionary genetics and genomics.
My main current researchinterests include evolution in spatially structured populations, evolution of ageing, and evolution of reproductive modes. I combine experiments with the analysis of NGS data. My main empirical study systems are the small crustaceans Daphnia and Artemia.
