My research focuses on understanding the evolutionary relationships of ancient land plants, especially ferns and horsetails, by integrating evidence from morphology, molecules (DNA sequence data from multiple genes), and the fossil record. I use an explicit phylogenetic framework to examine the morphological evolution of various sporophytic and gametophytic characters within vascular plants, and to gain insight into the evolution of various life history traits and the body plans that typify vascular plants. A phylogenetic perspective also informs my molecular evolutionary studies that attempt to elucidate why we observe remarkable rate heterogeneity in chloroplast genes in land plant phylogeny.
