Research Interests

My research concerns the systematics and evolution of flowering plants, with specific interest in the Ericaceae and Melastomataceae, phylogenetic relationships within temperate/tropical family pairs, and the floras of the West Indies and southeastern U.S. I have conducted field work mainly in the southeastern United States, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and the Virgin Islands. Currently, I am involved in taxonomic revisions of several Antillean clades of Miconieae (Melastomataceae), an investigation of the phylogeny of the Gaultherieae (Ericaceae), the treatment of several families for the Generic Flora of the Southeastern United States, and the production of an introductory textbook in plant systematics (Plant Systematics: A Phylogenetic Approach).

Research achievements include revisions of Agarista, Craibiodendron, Lyonia, Pieris, and subclades of Rhododendron (in the Ericaceae), and revisions of Miconia sect. Chaenopleura, and the Miconia desportesii complex (in the Melastomataceae). Other significant research includes published phylogenetic analyses of various clades within the Ericaceae and Melastomataceae.
