My research is focused on the evolutionary and genetic basis of natural variation in plants, and uses methods of population genetics, ecology and evolutionary genetics. Natural variation interests me broadly, including some complex life forms, such as polyploidy and asexual reproduction. How were these kinds of variation generated and how do they help plants adapt to natural or human-impacted habitats? Previous projects I have worked on include the speciation and adaptation of polyploid plants. Now I am using Boechera for studies of apomixis.
