Postdoctoral researcher

 

My main motivation is to find explanations to the origin and maintenance species. I have worked on various cases of speciation starting with butterflies and the effect that mating behaviour in driving a case of hybrid speciation, and in Australian endemic plants looking at the effect that adapting to contrasting environment has in populations divergence. Currently I am working in a project that studies the stable hybrid zone between two varieties of Snapdragons. This is a challenging project as it seems that flower colour is the only trait responsible to keep populations separate. Specifically I am interested in studying quantitative traits from the natural populations and explore possible pleiotropic effects of the flower colour loci. In this project we have a unique opportunity of study different aspects of evolutionary biology through the reconstruction of a multi-generational pedigree in the wild.
