Taxonomy and Systematics of Ferns and Lycophytes

We are interested in describing and understanding the diversity of ferns and lycophytes. For example, what the species are and where they occur—something often poorly known for tropical species and key to conservation efforts. We also study the evolutionary relationships among  species. We generate phylogenetic trees based on DNA sequences that show how the species are related and use the trees as a framework for answering questions about character evolution, biogeography, and evolutionary processes.
