Systematics and Biogeography of Compositae, Tribe Vernonieae
Biogeography of Hawaiian and Pacific plants
I am interested in the evolutionary and biogeographic relationships of plants that have dispersed over long distances, such as those found on islands and those with species in both the New and Old Worlds. Molecular sequence data from nuclear and chloroplast regions analyzed within a multi-faceted phylogentic framework form the primary basis for reconstructing relationships and inferring patterns of geographical movement. Biological attributes such as breeding system, morphology, and specialized dispersal mechanisms, as well as historical climate information, are also used. I feel that the most important part of my research centers around the evolutionary questions and therefore choosing the best group to provide those answers. As a result I encourage students to choose a plant group appropriate to their question whether that is one I have studied or not. I enjoy continuing to learn about the many and varied ways in which plant biodiversity has evolved across time and space.
