(Epi-)Genetics of social evolution

Our group is interested in the evolution of social behaviour taking an integrative approach from behavioural ecology over genomics to epigenetics. We focus on ants and occasionally on bees as model organisms as behaviours of these social animals are selected on different levels, are highly complex and include cooperative as well as conflict behaviours. We investigate the role of plasticity to generate different phenotypes via differential gene expression. We study the evolution of life history strategies, ageing and genomes of social insects. We are interested in how parasites affect and manipulate social insects and whether and how hosts can defend themselves against these attacks.
