Research Interests:

My laboratory is engaged in research on the systematics and evolution of vascular plants. Taxonomic groups of current interest are the Asteraceae and Euphorbiaceae. I am also interested in the evolution of desert flora, particularly population structure and the role of hybridization in speciation, and the biogeography and evolution of the flora of the West Indies specifically that of the islands of the Lesser Antilles. Methodologies employed for uncovering evolutionary relationships include the use DNA sequences of chloroplast and nuclear genes along with traditional techniques.
