The Ortiz-Barrientos lab studies both the origins of new species and how populations adapt to the environment. We test basic theories like the ecology of adaptive radiations, and the breakdown of coevolution during hybridisation. We also investigate the role of sexual selection in flowering plant speciation. We use both genetic and ecological tools, and perform experiments both in the laboratory and in the field. We approach these problems in Asteraceae species like sunflower daisies. Our research group is a diverse evolutionary genetics laboratory interested in solving fundamental questions in evolution.
