Peter is interested in social evolution and the evolution of mutualisms. Apart from the projects of the group, he is working on the ecological drivers of insect-fungus mutualisms and Darwinian agriculture. The latter tries to apply evolutionary processes to human agriculture and studies what humans can learn from farming insects for more sustainable agriculture. His main models are fungus-farming ambrosia beetles.
