I am an evolutionary genomics scientist with a research program centered on understanding how organisms adapt and diversify in nature. By using wild and domesticated plants as evolutionary model systems, my research combines emerging sequencing technology and phenotypic data from the field/lab with population genetic theory to uncover the evolutionary and ecological mechanisms that drive the phenotype and species diversity in nature.
