My research is at the interface of quantitative genetics, population genomics and bioinformatics. I use these tools to address key ecological and evolutionary questions from multiple perspectives with a particular interest in domestication, adaptation, conservation, and speciation. Much of my work focuses on identifying the genetic changes that underlie the formation of new species or varieties, and more generally, the genetic basis of novel phenotypes. Currently, I am using sunflowers (Helianthus), mustard (Brassica) and chocolate (Theobroma) as model systems to pursue these research questions. In all three genera, I am examining how hybridization has shaped evolution, including the origin of new hybrid species, the breeding of modern lineages of domesticated plants, and the spread of invasive species.
