Evolutionary biology aims at identifying the forces that drive species evolution and understanding how these forces in interaction with the environment shape the biodiversity. Among them, I have a peculiar interest for the process of natural selection. It is indeed natural selection that explains the adequacy between phenotypes and their environment. In my research group we are studying the genetic architecture underlying phenotypic traits involved in adaptation to environmental variation with a special focus on structural variations (aka macro-mutations). Our research finds outcome in plant breeding but also in conservation genetics.
