Members of the Nason lab are evolutionary biologists who use ecological and genetic approaches to study evolutionary processes. A common theme in our research has been investigation of the factors influencing gene flow and their impact on the structuring of genetic variation at various scales of organization, be it within populations, across natural landscapes, or between diverging species.
