Our primary focus is plant evolutionary genetics and genomics. More specifically, we're studying the genetic basis of evolutionary divergence within the sunflower family (i.e., the Compositae or the Asteraceae). We also maintain an interest in the ecological and evolutionary impact of transgene escape from genetically modified crops into their wild relatives.
