Speciation is a complex process that unfolds gradually across landscapes, generations, and genomes. Our research integrates ecological data, long-term field studies, and large genomic datasets to reveal how populations diverge, and how new species ultimately form. By linking genetic variation to traits, behaviour, ecological differences, and fitness in natural populations, we seek to understand the mechanisms that generate and maintain biodiversity.

​

We currently address key questions in speciation research using complementary plant and marine invertebrate systems. We study a natural hybrid zone between flower colour varieties of snapdragon (Antirrhinum) in the Spanish Pyrenees, where long-term ecological and genomic data allow us to examine how selection shapes hybrid fitness and reproductive isolation in the wild. We use intertidal snails from the genus Littorina to investigate how ecological divergence and genomic architecture contribute to local adaptation, isolation, and the evolution of novel reproductive strategies.​​​​
