About

I am interested in both patterns and processes in the evolution of plants. I work at the interface of population genetics and phylogenetics using a variety of genetic and analytical tools to investigate diversification of plants. My research program focuses on:

• Resolving relationships of closely related species, especially as influenced by polyploidy, hybridization, and ecological differentiation.

• Elucidating the environmental, geographical, and historical processes that affect patterns of diversification and distribution in plant populations in the arid American Southwest.

• Investigating genetic structure in populations of rare plants in order to gain a greater understanding of the evolutionary process and inform conservation action.
