We are interested in what the species of ferns and lycophytes are and where they occur—something often poorly known for tropical species—and the evolutionary relationships among the 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.
The evolution of leaves changed life on Earth. We study the expression and phylogeny of leaf development genes in lycophytes and ferns to better understand the evolution and development of leaves in the land plants.
