Research

  • Systematics, biogeography & evolutionary dynamics of species diversification in legumes (Leguminosae)
  • Revisionary taxonomy including taxonomic monographs of Leucaena & Lupinus.
  • Biogeography and the evolutionary dynamics of legume diversification. Our aim is to understand patterns and processes of evolutionary diversification across time and space. We are interested in why some groups of organisms have more species than others; why some evolutionary lineages diversify more rapidly than others; what are the explanations for these imbalances in the Tree of Life; how does diversification differ between lineages in different biomes; and what can this tell us about historical assembly of biomes? We work on the legume family, one of the most spectacular examples of evolutionary success in the flowering plants and one of the most economically important groups of plants. Our recent work has looked at plant diversification in the high elevation Andes, seasonally dry neotropical forests, and the Cerrado biome of central S. America. Current work focuses especially on mimosoid legumes and the genus Lupinus as models for investigating plant diversification.
  • Use of next generation sequencing to build next generation phylogenies with massively enhanced taxon and gene sampling for large clades that cover broad temporal, geographic and ecological spans.
  • Early legume crop domestication in Mesoamerica and the Andes.

Plant Systematics and Evolution

My research focuses on plant systematics, biogeography and the evolutionary dynamics of species diversification. Our aim is to understand patterns and processes of evolutionary diversification across time and space. We are interested in why some groups of organisms have more species than others; why some evolutionary lineages diversify more rapidly than others; what are the explanations for these imbalances in the Tree of Life; how does diversification differ between lineages in different biomes; and what can this tell us about historical assembly of biomes? We work on the legume family, one of the most spectacular examples of evolutionary success in the flowering plants and one of the most economically important groups of plants. If you are interested Masters projects in these areas, please contact me for further information. List of possible projects.
