Research interests

Kin selection is thought to be an important driver in the evolution of cooperative societies, where breeders and other individuals collaborate in raising offspring. However, many species exhibit a complex within-group relatedness structure, where indirect fitness benefits alone cannot explain helping behaviour. In my PhD studies I investigate the costs and benefits of breeders that accept helpers, as well as the direct and indirect fitness benefits gained by helpers. I am furthermore interested in how environmental heterogeneity shapes such social systems.
