Role

Systematics, biogeography, diversity and biology of neotropical Leguminosae, especially Caesalpinioideae (particularly Caesalpinia) and Mimosoideae.

Research focuses on the systematics of neotropical (mainly South American) Leguminosae, principally subfamilies Caesalpinioideae and Mimosoideae. Floristic work has been in the drylands and wet tropics of Brazil and the Andes of Ecuador, including monographic work on the large genus Caesalpinia. Research and publication is multidisciplinary (including: taxonomic revision, phylogenetic studies, reproductive biology, floral anatomy, phytochemistry and biogeography) and involves international networks and capacity-building through training and data repatriation. Fundamental identification services facilitate legume work in conservation and sustainable use, both at Kew and globally. Higher level systematic studies contribute to an improved legume phylogeny through international collaborative efforts and publication and dissemination of the results.
