I have a profound interest in the evolution of social organization and particularly on how individuals or animal societies evolve with their environment. Having an expertise in behavioural ecology from my past education, I am combining this field to genomics in my PhD project.

PhD project

Coevolution between antagonistic species can drive evolutionary arms races - reciprocal cycles of coadaptation. Recent advances in sequencing technologies allow now to study the molecular basis of evolutionary adaptations on a genomic level in non-model systems. In this project, we focus on a well-studied host-parasite system consisting of the slavemaking ant Temnothorax americanus, an obligate social parasiteand its related host Temnothorax longispinosus, for which ample evidence for coevolution and local adaptation exists. We will use populations of a “natural experiment”, in which host and parasite evolve in sympatry (=coevolve) or allopatry. We propose to study the genetic background of adaptations, the types and strength of selection and whether mainly regulatory regions or protein- coding genes are important for coadaptation. . By analyzing multiple populations under similar selective regimes, we can reveal whether coevolution takes different avenues in different locales or whether it occurs in parallel.  Overall, our study will contribute to a better understanding of genetic mechanisms of adaptation during coevolution.
