My work focuses on the interplay between the organisation of genomes arising by the chromosomal interactions of cellular processes and the recombination processes generating adaptive genetic variation. Genetic elements tend to be organized in genomes by natural selection in order to optimize this highly complex structure. Yet, they are also constantly faced with genomic variations including mutations, amplifications, rearrangements and horizontal gene transfer. I study the conflict between organisational features and the adaptive plasticity of genomes and how it determines genome evolution and ecological adaptation.
