Research focus

Our research seeks to reconstruct the recent history of adaptive molecular variation in plant systems. In other terms, we aim at dissecting the molecular mechanisms of Darwinian evolution in complex natural systems. We work with the weedy annual and model plant species Arabidopsis thaliana and its close relatives A. lyrata and A. halleri. Our work focuses on understanding links between life history strategies and fitness. We further intend to develop new methods to track the action of natural selection at the molecular level. These methods could find wide applications in CEPLAS.
