Evolutionary genomics of natural populations

Characterizing the genetic basis of traits of importance for local adaptation and species recognition is a major aim for evolutionary biologists of today.
We use a combination of genetic mapping, population genetics and comparative genomics approaches to study the speciation process, the genetic basis of adaptive traits and patterns of genome evolution. We are primarily using natural populations of butterflies as study organisms.
